troubleshooting, and daily maintenance of the AC motor drives. To guarantee safe operation of the
equipment, read the following safety guidelines before connecting power to the AC drives. Keep this
operating manual handy and distribute to all users for reference
DANGER !
1. AC input power must be disconnected before any maintenance. Do not connect or disconnect
wires and connectors while power is applied to the circuit.
2. A charge may still remain in the DC-link capacitor with hazardous voltages even if the power has
been turned off. To avoid personal injury, please ensure that power has turned off before operatingAC drive and wait ten minutes for capacitors to discharge to safe voltage levels.
3. The AC drive may be destroyed beyond repair if incorrect cables are connected to the input/output
terminals. Never connect the AC drive output terminals U/T1V/T2and W/T3 directly to the AC
main circuit power supply.
4. The A-SERIES is only for 3 phase induction motor, other application will not be suitable.
5. Ground the A-SERIES using the ground terminal. The grounding method must comply with the
laws of the country where the AC drive is to be installed. Refer to Basic Wiring Diagram. PE
terminal must be ground correctly, 230V the 3
rd
way.
WARNING !
1. There are highly sensitive MOS components on the printed circuit boards. These components are
especially sensitive to static electricity. To avoid damage to these components, do not touch these
components or the circuit boards with metal objects or your bare hands.
2. Do not test the A-SERIES with pressure.
3. Even the motor is stop, the main circuit may still have dangerous high voltages inside.
4. Maintenance must be performed by qualified technicians.
WARNING !
1. Please select safe area to install A-SERIES. Keep this A-SERIES from high temperature, direct
sunlight, moisture and splashing of water droplets.
2. When the cable between inverter and motor is too long, the layer insulation of motor may be
damaged. Please change to use professional AC motor or install another resistor between inverter
and motor to prevent burn down of motor.
3. The rated voltage for power system can not be over than 240V, current can not be over than 5000A
RMS.

Ramp to stop: The drive will ramp down from operation frequency to startup
frequency (Pr1-20) based on the deceleration time.
Coast to stop: The drive will stop the output instantly upon a STOP command and the motor
will coast to stop according to its inertia (time unknown).
In applications where the motor must stop after the drive is stopped, please select Ramp to
Stop. This is often a safety consideration.
If the inertial load is large, it is recommended to set the drive for Coast to Stop to eliminate

Example: To display rpms for a 4-pole 60Hz motor with a base speed 1800rpm and no slip,
Pr1-02 must be set to 0.The result of setting 1800 in Pr1-01 determines the value at 60Hz
(Maximum Output Frequency).. In case of higher resolution need to set Pr1-01=18000 and
Pr1-02=1, then get 1800.0rpm readout, 0.1rpm resolution.
After this parameter is set, all functions relative to the frequency (except for the V/F Curve
frequency parameters) will automatically be changed to an RPM scale. RPM, instead of Hz,
will now be the unit for the keypad, and thus, if it is displayed as 60.00 before the setup,
it will now display 1800 after the setup. Other parameters such as the multi-step speed and
JOG will be automatically changed also.
1-03 Motor1 Base Frequency
Settings 0.00600.00 Hz Factory Setting 50.00
This parameter sets the frequency, where the maximum output voltage (Pr1-02) will be reached.
The output frequency may exceed this setting, but the output voltage doesnt increase beyond
this point. This parameter should be set according to the rated frequency of the motor as indicated
on the motor nameplate.
If this parameter setting is smaller than the rated frequency of the motor, nuisance over current
faults or damage to the drive may occur. If this parameter setting is greater than the rated
frequency of the motor, the motor will encounter torque loss.
This parameter must be set to the motors nameplate frequency rating.

Input current of the motor could divide into two orthogonal vectors: magnetic vector and torque
vector. Gap flux, which is produced by Magnetic vector, is in direct proportion with output voltage
of motor. Torque vector produces torque. Torque is in direct proportion with the result of
magnetic vector multiply by torque vector. In theory, if the value of magnet vector is the same
with torque vector (in unsaturated flux condition), the input current is inimum. If motor loading is
unsteady torque loading (loading torque is in direct proportion ith speed. For example, the
loading of fan or pump), loading torque is low during low speed, suitable lower input voltage will
decrease input current of magnetic field to lower flux oss and iron loss of the motor and promote
whole efficiency.
When this parameter is set to high power V/F curve and low frequency torque is lower, it is not
suitable for drive to accel/decel quickly. If it needs to accel/decel quickly, it is not ecommended
to use this parameter.
Please ensure the at-site loading, and then select the proper V/F curve.

The Acceleration time is the time required for the Drive to ramp from 0 Hz to its Maximum
Operation Frequency (Pr1-00). Deceleration time is the time required for the Drive to decelerate
from Maximum Operation Frequency (Pr1-00) down to 0 Hz.
An Acceleration or Deceleration time that is too quickly, may cause the Drive protection features toenable (over-current stall prevention during Accel Pr4-17 or over-voltage stall prevention Pr4-14).
If this occurs, the actual Accel/Decel time will be longer than this setting.The
acceleration/deceleration times will be disabled if Pr1-23. (Auto acceleration/deceleration
Selection) is set for automatic operation.
Acceleration/Deceleration times 2,3,4 is enabled by using a multi-function terminal set to 7,8.
Acceleration/Deceleration time 1 is the factory default for out-of-the-box operation.
Warning:An acceleration or deceleration that is too quickly, may cause excess loads on
the drive and may permanently damage the drive. If you want to decelerate the Drive in short time period, we recommend adding an external

Settings ****A10~100%
This parameter will limit the Drive output current in order to prevent the motor from overheating.
The value entered must be in Amps, and should be found on the motor nameplate.
This parameter must be programmed correctly if the drive is to operate in the Vector or Torque

4-24-0244 Motor1 Torque Compensation
Settings 0.025.0% Factory Setting 0.0
This parameter increases the amount of voltage the drive will output to the motor during operation
to increase motor torque. The V/F Torque Compensation is based on the setting
of the parameter.Be careful when setting this parameter. Always start at the lowest setting and increase the
value until sufficient torque is achieved. A large Torque Compensation may generate more
voltage than needed and the motor will overheat and possibly be damaged.
4-03 Motor1 rate speed(Slip Compensation) Factory Setting 1500
04-2804 Settings 100%~75% of rate rpm
While driving an asynchronous motor, an increasing load will cause an increase in slip. This
parameter may be used to compensate the nominal slip within a range of 0.0-10.0% (Pr1-01).When the output current of the drive is higher than the motors no-load current, the drive will adjust
the output frequency to the motor to compensate for slip.
Note 1. If the motors no-load current > the rated current of the motor, the slip compensation
will not work correctly.
Note 2. To obtain effective slip compensation, use the auto tune feature Pr4-05.

Settings 1 tuning Factory Setting 0
This parameter automatically measures the motors characteristics and enters the values into
Pr04-01, Pr04-02, Pr1-08,Pr1-09(Motor1) or Pr04-07, Pr04-08, Pr1-18,Pr1-19(Motor2),
respectively.
Motor Auto Tuning Procedure:
1. Make sure all the parameter settings are at the factory settings and all power wiring is correct.
2. Enter the motor rated voltage in Pr1-03(Pr1-13) and motor rated frequency in Pr1-02(Pr1-12).
And Full-Load current in Pr4-00(Pr4-06).
3. Set Pr4-05 = 1, then press the RUN key on the keypad to execute the motor auto-tuning
operation The execution time is about 15seconds.
4. After the auto tuning procedure is complete, verify the parameters Pr04-01, Pr04-02,
Pr1-08,Pr1-09(Motor1) or Pr04-07, Pr04-08, Pr1-18,Pr1-19(Motor2) have been updated. If not,
set Pr4-05 = 1 and press the RUN key again.
The drive is now switch to Sensorless Vector control mode.
(Proper setting Slip Compensation of Motor1 in Pr4-03(Pr4-09), may get optimam control
result)
Note 1. The sensorless vector control mode is not intended for use with multiple motors connected
to one Drive.Note 2. If two motors will be connected to one drive and both must be auto tuned, it is necessary to
set a multi-function input terminal to switch between Motors 1 and 2.
This will enable the drive to enter the calculated values into the correct parameter positions.

The action level of the braking resistor could be set by this parameter. The value must be
higher than the steady state DC-BUS voltage; otherwise the braking transistor will have a
100% duty. At 100% duty the transistor and resistor will most likely fail.

The phase-loss protection is for the input side of the power phase-loss protection. The drive will
have influence on control characteristics and driver life when it operates the input phase-loss. But
it can be operated if its output current is less than 50% of rated current.
4-17 OC Stall Prevention during ACC
Settings Amp (10250) Factory Setting A(170%)
This value sets the current limit for the Over Current Stall Prevention function. During acceleration,
a heavy loaded motor may require very high current. If the current reaches the value programmed
in Pr4-17, the drive will stop acceleration, hold speed and wait for the current to dissipate in the
motor. Once the current has fallen below the limit set in Pr4-17, the drive will begin to accelerate to
command speed as shown in the graph below.

Settings Amp (10250) Factory Setting A(170%)
This parameter sets the current limit for the Over-Current Stall Prevention during Operation
function.
If the load on the motor causes the current to rise above the value set in this parameter, the drive
will lower its output frequency (therefore lowering current) to avoid the motor from stalling.
After the current has fallen below the value set in Pr5-12, the drive will begin to bring the motor
back to command speed as shown in the graph below.

These parameters define the current level and detection time for the Over Torque Detection
function.
The Over Torque1 Detection is a current level .The factory setting, Pr4-24, is 150% of the drive
rated current.
The Over Torque1 Detection time is the length of time the drive may be in an over torque
condition.
Example: When the output current exceeds the over torque detection level (Pr4-24) and exceeds
the over torque detection time (Pr4-25), the drive will display ot1 on the keypad and will follow the
setting in Pr4-23.

4-35 DC Braking Current Level Factory Setting A(0%)
Settings Amp (0~125%)
This parameter sets the DC braking current level in percentage, for use with DC injection braking.
The percentage is based on the rated current of the Drive. When programming this parameter, be
sure to increase the percentage slowly from 0, until sufficient braking torque is obtained. A current
level too high may damage the motor.
4-36 DC Braking Time at Start-up Factory Setting 0.00
Settings 0.0060.00 Sec
This parameter determines the duration of DC braking current applied to the motor immediately
following a START command.
3-37 DC Braking Time during stop Factory Setting 0.00
Settings 0.0060.00 Sec
This parameter determines the duration of DC braking current applied to the motor upon a STOP
command. This is often used to hold a motor shaft in position for a short time.

value set in this parameter.
Immediately following a RUN command, the drive will output a DC current until the output
frequency reaches the value set in this parameter.
The DC braking is commonly used to help decrease the deceleration time. For the best stopping
performance, it is recommended to use the Deceleration Time to slow the motor and then applythe DC brake.
4-39 Gain for DC Braking Factory Setting 20.00%

Settings 0.130.0 Sec
During a power loss, if the power loss time is less than the time defined by this parameter, the
Drive will resume operation. If the Maximum Allowable Power Loss Time is exceeded, the Drive
output is then turned off.
If the power loss occurs while the drive is under heavy load, it is possible all available rides
through power will be dissipated in the motor and the drive will shut down quickly (less than 1
second).
The Momentary Power Loss function is only enabled while the LV is displayed on the keypad.
