CONTROL and OTHER FUNCTIONS

5. CONTROL and OTHER FUNCTIONS

5.1 RUN STATES OF MOTOR PMAC801 divides motor running process into five status in order to provide perfect protection for motors:

“Ready”: in this state, motor can be started immediately.

“Starting”: From motor start to operate till running smoothly

“Running”: Motor running smoothly.

“Stopping”: Motor start to run till hot capacitor decrease to 15% of rated after receive stop command.

“Stopped”: After its hot capacity less than 15% of rated, the controller indicates that the motor comes into

stopped state. In this state, if there isn’t fault information of motor, the run state will be changed from stopped

state to ready state automatically. If there is fault information of motor, the state won’t be changed, and the

controller doesn’t implement start command. If a reset signal is given to the controller, the fault information

will be eliminated. Stopped state is finished and ready state comes.

5.2 OPERATION PERMISSION

Motor can be controlled through display module, remote DI or communication respectively.

Local control means that only commands from the keypads of display module are active.

Remote DI control means that only commands from DIs are active.

Remote communication control means that only commands from communication are active.

Operation permission of the controller can be set as local or remote via DI6. If status of DI6 is open, it means

local permission. If DI6 is closed, permission will be changed to remote DI. Through communication software,

permission can be changed from remote DI to communication.

Under protection mode there isn’t the difference of operation permission and only reset command is active.

5.3 PROTECTION/CONTROL Relays in controller have double functions of control and protection.

Via keypads, DI or communication, motor can be started and stopped normally.

When a fault takes place and the corresponding protection action mode is trip, controller will send signal to the

control relay, and trip will take place. The motor will be stopped. The reason of trip can be got from display

module and communication software.

There is an overflow relay in the controller, when the current of motor is bigger than the cut ability of contactor,

the relay will give a pulse to breaker to stop motor.

5.4 FAULT INFORMATION OUTPUT PMAC801 provides a relay output for fault information. Its contact is open normally. When alarm or trip

protection takes place, the contact will be closed. After the fault is eliminated, the contact is opened again.

5.5 POWER DIAGNOSIS PMAC801 provides a relay for power diagnosis output. Its contact is closed normally. When PMAC801 is

powered on, the contact will be opened. And if PMAC801 is powered off, the contact returns to be closed.

CONTROL and OTHER FUNCTIONS

13

5.6 RESET If PMAC801 stopped the motor because of the motor’s fault, when the motor comes into stopped state, the

controller should be reset to clear fault indication before restarting motor. Reset operation can be implemented

via reset keypad of display module, DI4 of controller or communication.

Reset operation can clear hot capacity. If user needs to restart motor peremptorily, you don’t need to wait until

motor comes into stopped state; when motor is in stopping state, users pressing reset key can clear hot

capacity and fault information to make motor come to ready state.

Note: In order to avoid starting a hot motor, please don’t reset the controller in motor’s stopping state, unless

emergency.

5.7 EMERGENT STOP

PMAC801 provides an emergent stop operation input. If the input is active, the motor will be stopped

immediately and hot capacity will be cleared at the same time. Motor won’t be allowed to start unless the input

is eliminated.

5.8 RESTART FUNCTION

In case of a voltage dip, PMAC801 will restart the motor in certain cases according to the length of the dip, after

the voltage restores. The function needs the power supply module to ensure the controller works for a period

of time after the voltage dips. In the period of time, if the voltage can’t restore, the restart function will be

noneffective.

DISPLAY and KEY FUNCTIONS

14

6. DISPLAY and KEY FUNCTIONS

The main function of the display module include: displaying measurement values and fault information, setting

parameters and controlling motor.

A special cable can connect the display module and the main module. If the main module is powered on, the

display module will be powered on.

The display module uses a 2 X 7 font LCD. After the module is powered on, its backlight will be turn on for 10s.

If keypads operation takes place, the backlight will be turn on for 10s again.

6.2 KEYPADS OPERATION

Display module has 2 groups of keypads. One group is control keypads, and the other is set keypads.

Control keypads: “Start A”: Start motor in direction CW. “Start B”: Start motor in direction CCW. “Stop”: Stop motor. “Reset”: In the stopping or stopped state, pressing the key 2s can eliminate fault information..

Set keypads: “←”: Switch the display interface and the setting interface to the control interface, or return to the previous

menu. “↑”: Switch display interface or increase setting value. “↓”: Switch display interface or decrease setting value.

“ ”: Enter button or press for 3s. Interface will switch to setting interface

6.3 PORTS:

There are two ports in the display module. The port in the front is reserved for debugging. Through a special

cable, the controller can communicate with PC.

The port in the back is used to connect with main module or extended module.

6.4 DISPLAY CONTENTS The display module has three kinds of operation modes: motor control mode, read mode and setting

mode.

Motor control mode:

After the display module is powered on, the default operation mode is the control mode.

Under the control mode interface, if the run state of motor is “Ready”, the motor starting control mode will be

displayed instead. If the run states of motor are “Starting”, ”Running”, ”Stopping”, or “Stopped”, characters

“Starting”, ”Running”, ”Stopping”, or “Stopped” will be displayed separately.

If the operation permission is local, under the control mode, operating keypads of the display module can start,

stop and reset motor.

Operating “←” can switch the other modes to the control mode. If there is no operation on the keypads for 1

minute, the modes return to the control mode automatically.

Read mode:

Pressing any of set keypads shortly can switch the control mode to the read mode.

Note:

1. ”﹡” means optional protection function.

2. If users decrease protection action value to 0, the protection function will be disabled.

8.2 PROTECTION EXPLANATION Protection parameters of PMAC801 can be set through display module or communication software.

Only start overtime, overload, phase failure, and short circuit protection functions are primarily enabled. Users

can enable the other protection functions according to requirements. Please be cautious when setting

protection parameters, in case of bringing controller’s mis-protection or motor’s damage.

Additionally, during motor’s starting state, only start overtime, phase failure, unbalance (if enabled),

earth/leakage (if enabled), short circuit (if enabled), external fault (if programmed), phase sequence error (if

enabled) and EEx e overload (if enabled) protections are active, the other protections won’t be active until

motor comes into running state.

◆ START OVERTIME PROTECTION

Start overtime protection is active just during motor’s starting state. The protection function can’t be disabled.

Users can set the start time according to the motor’s actual start time i.e. the time from when motor starts to


28

when motor comes to rated speed. Usually the time can be set as 1.2 times of actual start time.

During motor’s starting state, after the set start time is expired, if Iav ≥1.2 times of Ie or Iav≤0.1 time of Ie,

start overtime protection will act immediately.

Default parameters:

Start time 5s

Action mode Alarm

◆ OVERLOAD PROTECTION

Overload protection prevents motor from running over rated current for long time and being damaged. The

controller simulates heating characteristic of motor to protect it. The protection function can’t be disabled. And

it is just active during running state.

The curve speed K should be set according to the motor’s overload level. The following is the relation of K and

overload level.

K Overload level Times of rated current 1.2 1.5 7.2

130,180 10A ≤2min 2s<t≤10s

280 10 ≤4min 4s<t≤10s

400,600 20 ≤8min 6s<t≤20s

800,1000 30

Delay time Less than an hour

≤12min 9s<t≤30s

Hot/Cold is used to calculate the motor’s hot capacity. It is achieved from the following formula.

Hot/Cold =（100×Hot rotor locked time∕Cold rotor locked time）*100%

Hot rotor locked time and cold rotor locked time can be found in motor’s technical specification. Or its typical

value is 85%. After motor stops, its cool speed is affected by the cool time set by users. Cool time can be set according to the

motor’s cool condition. The typical time is 30 minutes.

If the fault reset mode is manual, after motor stops because of overload fault, users should reset controller

manually to clear fault indication and hot capacity. If the fault reset mode is automatic, after motor stops,

manual operation is unnecessary. After hot capacity falls under 15%, fault indication will be cleared

automatically, and motor can be restarted.

During the motor’s running state, if Iav>1.05 times of Ie, overload protection function will start to calculate

delay time according to time-current curves, and act after delay time is expired. If Iav ≤ 1.05 times of Ie, the

protection won’t act. The error of delay time is ±10%.

Overload protection have 16 types of inverse time-limit time-current characteristics curves.

Protection action mode Alarm

◆ OVERCURRENT PROTECTION

Overload protection prevents the motor from being locked because of heavy overload or other mechanical

reasons.

Users can set the action value of overcurrent protection according to motor’s max locked current provided by

manufactures. The value can be set as half of motor’s max locked current, and usually it is 1.5~2.5 times Ie.

During the motor ‘s running state, if Iav≥1 time of the action value, overcurrent protection function will start

to calculate the delay time, and act after the delay time is expired. If Iav < 1 time of the action value, protection

won’t act.

The error of delay time is ±100ms.


30

◆ PHASE FAILURE PROTECTION

If any phase < 5% of Ie, protection will act after the delay time is expired. The protection function can’t be

disabled.

The error of delay time is ±2 cycles.

Default parameters: Delay time 2 cycles

Action mode Alarm

◆ CURRENT UNBALANCE PROTECTION

Current unbalance is a main reason to lead to motor’s hot damage. When unbalance takes place, if unbalance

rate reaches the protection action value, controller will alarm or trip.

Once unbalance protection is active, if the current unbalance rate ≥1 time of the action value, the protection

will start to calculate the delay time, and act after the delay time is expired. If the unbalance rate < 1 time of

the action value, the protection won’t act.


◆ SHORT CIRCUIT PROTECTION

Short circuit current will generate mass of hot, and slow action will lead motor to burn out. The controller

provides prompt protection for motor.

If motor’s short circuit current is bigger than the cut ability of contactor and the protection action mode is trip,

the overflow relay of the controller will give a pulse to breaker to stop motor. The contactor will be cut after

the current falls down the cut ability.

During the motor’s running state, if any phase current ≥1 time of the action value, the protection will start to

calculate the delay time, and after the delay time is expired, if the current < the allowed cut current of contactor,

the protection will act to cut the contactor. If the current < 1 time of the action value, the protection won’t act.

The error of delay time is ±2 cycles. ◆ EARTH FAULT PROTECTION

Earth fault protection will work when rotor’s coil is short connection with ground. The connection point

determines the magnitude of earth current. Low action value will protect more coils.

After Earth fault protection is active, if Ig≥1 time of the action value, the protection will start to calculate

delay time, and act after delay time is expired. If Ig < 1 time of the action value, the protection won’t act.


Default parameters:

Action value 20%Ie


31

Delay time 2 cycles

Action mode Alarm

◆ LEAKAGE CURRENT PROTECTION

Leakage current protection provides more precise check of earth current to prevent people from injury.

After leakage current protection is active, if I△≥1 time of the action value, the protection will start to calculate

the delay time, and act after the delay time is expired. If I△< 1 time of the action value, the protection won’t

act.


The leakage current protection is optional. If the function is selected, users can set the item ”earth or leakage”

to leakage.

◆ UNDERLOAD PROTECTION

Underload protection prevents motor from uneconomical energy spoilage.

During the motor’s running state, if Iav ≤ 1 time of the action value, the protection will start to calculate delay

time, and act after the delay time is expired. If Iav > 1 time of the action value, the protection won’t act.


◆ EXTERNAL FAULT PROTECTION If a DI is programmed as external fault input, the active input will touch off the external fault protection. After

the DI is cleared, the fault information will be cleared automatically.

◆ UNDERVOLTAGE PROTECTION

Low voltage may make motor’s rotate speed slow or motor stop.

During the motor’s running state, if any phase/phase voltage ≤ 1 time of the action value, the protection will

start to calculate the delay time, and act after the delay time is expired. If all phase/phase voltage >1 time of



◆ OVERVOLTAGE PROTECTION

Overvoltage may make insulation damaged. Because motors can usually work under 1.2 times of Ue, the action

value can be set as 120% of Ue.

During the motor’s running state, if any phase/phase voltage ≥1 time of the action value, the protection will

start to calculate the delay time, and act after the delay time is expired. If all phase/phase voltage < 1 time of



32


◆ UNDER POWER PROTECTION

Under power protection provides motors with better underload protection.

During motor ‘s running state, if the total value of three phase active power ≤ 1 time of the action value, the

protection will start to calculate the delay time, and act after the delay time is expired. If the value > 1 time of



◆ PHASE SEQUENCE ERROR PROTECTION

Wrong phase sequence can make motor run in wrong direction. The protection prevents motor from being

started in wrong direction.

◆ EEx e OVERLOAD PROTECTION (te time protection)

EEx e overload protection is for explosion proof three phase induction motors. The trip time of the protection

from the cold state motor must be less than the te time rated for the motor.

A trip time curve is provided to implement the protection in the controller. The trip time curve is below the curve

provided by GB3836.3-2000, and is suitable for the motors, which conform to GB3836.3-2000.

te characteristics curve:

① The curve is provided by GB3836.3-2000.

② The curve is provided by the controller. ◆ ANALOG CURRENT INPUT PROTECTION Analog current input protection is designed for non-electrical parameter. It can measure 4~20mA current input

and make a protection output according to the measurement.


33

◆ OVERTEMPERATURE PROTECTION

Impedance of hot resistance imbedded in motor stator can change according to temperature’s change.

The te hot sense resistance can be connected with the controller, when the impedance reaches the action value,

the controller will trip or alarm.

PTC: If the real time impedance ≥the action value, then the controller will act after the delay time. If the

action mode is alarm, the alarm information will be cleared automatically when the impedance < the return

value.

NTC: If the real time impedance ≤the action value, then controller will act after the delay time. If the action

mode is alarm, the alarm information will be cleared automatically when the impedance >the return value.

The delay time is 1s. The error of delay time is ±100ms.

9. SYSTEM PARAMETERS

◆ RATED CURRENT of MOTOR

Range: 0.5 A~ 820.0A.

◆ RATED VOLTAGE of MOTOR

Range: 100 V~ 690 V.

◆ RATED POWER of MOTOR

Range: 0.5～600kW.

◆ RATE of EXTERNAL CT

Because PMAC801 has its special independent CT, and the rated current of the CT is up to 820A. Generally it

doesn’t need the other CTs. In case the other CTs are used, the rate of the CT should be set. For example, if the

other CT is 500A/5A, the rate is 100.

Range: 1~2000.

◆ EARTH/LEAKAGE

Range: Earth, leakage.

Earth fault protection and leakage current protection can’t exist at the same time. Users can select any of them

through display module or communication.

Earth fault protection uses three composite vector modes to calculate the Zero phase sequence current. Leakage

current protection needs external leakage CT.

◆ PRIMARY RATED CURRENT of LEAKAGE CURRENT CT Range: 1mA～1000mA.

If users select the leakage current protection, a leakage current CT is needed. PMAC801 supports the CT, which’s

secondary rated current is 4mA. The primary rated current of the CT can be set according to real value.

◆ CUT ABILITY of CONTACTOR Range:6.0～10.0Ie

◆ STARTING CONTROL MODE

Range: protection mode, direct starter, reversing direct starter, star/delta starter, Loop-open star/delta starter

with 3 relays, Loop-close star/delta starter with 3 relays, autotransformer starter, Loop-open autotransformer

starter with 3 relays, Loop-close autotransformer starter with 3 relays, breaker direct starter.

The default mode is direct starter.

◆ ANALOG TYPE

Range: Ia, Ib, Ic, Ig UnI, Uab, Ubc, Uca. The parameters can be chosen to correspond to the analog current

output.

◆ ANALOG MULTIPLE

Range: 1.0~10.0.


35

When the multiple of analog is set 2, the relations of analog and corresponding current output 20mA are listed

as follow:

Sort Corresponding Value

of 20mA Sort

Corresponding Value

of 20mA

Ia 2 times of rated value UnIav 200%

Ib 2 times of rated value Uab 2 times of rated value

Ic 2 times of rated value Ubc 2 times of rated value

Ig 2 times of rated value Uca 2 times of rated value

◆ COMMUNICATION ADDRESS Range: 1～247（Modbus-RTU）;

3～123（Profibus-DP）.

◆ BAUDRATE

Range: 2400,4800,9600,19200.

The default is 9600.

◆ CHECK on FEEDBACK of CONTACTORS

Range: Disable/Enable.

If the function of check on feedback of contactors is enabled, the controller will check the state of contactor

firstly. If the state is error, “Feedback Error” will be displayed and the fault information relay will be closed. If the

state is right, the fault information will be cleared.

◆ OPERATION PERMISSION

Range: Remote DI/Communication.

After the DI6 is active, the operation permission is switched to remote. It includes remote and communication.

The parameter only can be set via communication.

◆ SYSTEM FREQUENCY

Range: 50HZ/60HZ. The default is 50HZ. The parameter just can be set via communication.

◆ RESTART FUNCTION

After a motor is started, if a undervoltage protection happens, or a voltage dip results in contactor to break and

the voltage drops down the undervoltage protection action value (undervoltage protection is enabled) or 70% of

rated voltage (undervoltage is disabled), the controller will open the control relay inside, and give a voltage dip

information.

In case a voltage dip, the controller start to cumulate the dip time till the voltage rises above the programmable

voltage restoration level (VRL). If the dip time isn’t over the programmable allowed dip time (ADT), the motor

will be restarted after the start delay time (SDT) is expired. If the dip time is over the allowed dip time, the motor

won’t be restarted, and all dip information will be cleared.

The function is noneffective under the Motor starting control mode of protection mode.

Under protection mode, contact of relay A is in series with coil circuit of contactor C1, after powering on

controller, the contact of relay A is closed immediately, then motor can be started via remote control switch. If

a protection action takes place, contact of relay A will be opened, then contactor C1 will be opened and motor

stops. After motor comes into stopped state, fault information can be cleared via reset operation. And then relay

A will be closed, motor can be restarted.

Under this mode, the functions of check on feedback of contactors and restart are noneffective.

Under star/delta mode, after powering on controller, “S/D Starter” will be displayed. Under the ready state of

motor, if command START A is given, the contact of relay A will be closed, and then the contacts of C1 and C3

contactors will be closed. Motor is started under Y mode. During starting, LED ”START” is lighten, and “Starting”

is displayed. When the start time elapses, the contact of relay A will be opened, and the contact of relay B will

be closed. Then the contact of C1 contactor will be opened, and the contact of C2 contactor will be closed. Motor

will run under △ mode. LED ”START” is off, and LED ’’RUN” is lighten. “Running” is displayed. If command STOP

is given, the contact of relay B will be opened, and the contacts of contactor C2 and C3 will be opened. Motor

stops.

If a fault takes place, and protection action mode is trip, the controller will stop motor. After motor comes into

stopped state, fault information can be cleared via reset operation, motor can be restarted.

doesn’t work. Check terminals L/+ and N/- to ensure proper input voltage.

The measurement value of current

isn’t right.

Check if the current is in the measurement range of the controller.

Check if the rated current of motor and CT are set properly.

The measurement value of power

isn’t right. Check the phase sequence of current and voltage.

Relays misact. Check the motor starting control mode.

Check the address.

Check the baudrate. No communication.

Check if the terminal resistance is missed.
