Solution

Problem

Overview

Problem Problems:

1. Simotion CPU goes to Stop

2. frequent encoder error or TO-error

3. Invert-ready signal comes and goes

4. PLC-control does not work

5. Too long time for axis switchover

6. Trolley’s reaction is too slow

7. Project doesn’t work after copy and paste

8. Axis switchover takes too long time

V2.0 SP2 has default setting to

aviod problem 1&2


Solution

Problem

Task-Configuration Setting

Problem 1: CPU goes to stop

Solution:

- ‘Task configuration’ in ‘execution system’ should NOT be set at ‘error reaction with program error’ with

CPU in Stop but ExcutionFaultTask

- If the reason is task overflow, then ‘Task configuration’ in ‘execution system’ can be set at ‘number of level overflows in the loop clock’

max. 5

Solution


Solution

Problem

TO-Configuration setting (1)

Problem 2: frequent encoder error

Solution: expert listconfiguration data, set 'TypeOfAxis.NumberOfEncoders.Encoder_1.SensorControlConfig.tolerateSensorDefect’ to YES

Solution


Solution

Problem


Problem 2: frequent TO-error

Solution: expert listconfiguration data, set

‘TypeOfAxis_DriveControlConfig_pulsesEnabled_bitNumber’ to 11

'TypeOfAxis_DriveControlConfig_pulsesEnabled_pzdNumber to 4

'TypeOfAxis_DriveControlConfig_releaseDisableMode to 7

Solution


Solution

Problem


Problem 2: frequent TO error


'RestartCondition.restartAxisCondition’ to NO_CONSTAINTSSolution


Solution

Problem


Problem 2: frequent TO error


'Restart.behaviorInvalidSysvarAccess’ to DEFAULT_VALUESolution


Solution

Problem

TO-Mechanics Setting

Problem 3: Invert-ready signal comes and goes

Solution: Setting

- Load gear / Measureing gear / Leadscrew pitchSolution

Leadscrw pitch = diameter of wheel / drum * π


Solution

Problem

TO-Monitoring Setting (1)

Problem 3: Invert-ready signal comes and goes

Solution:

- Following error

Deactivated at beginning Setting at the end of commissioning

Solution


Solution

Problem

TO-Monitoring Setting (2)

Problem 3: Invert-ready signal comes and goes Positioning and Standstill

Solution


Solution

Problem

PLC-program

Problem 4: PLC control does not work

Problem 5: Switchover takes too long time

Solution: Correct sequence (PLC) for activating of function

- refer to application examples of S7 control (Chapter 8.4)

- refer to S7-Program examples on CD (V2.0 SP2)

Efficient programming- Do not use unnecessary Timer or too long Timer


Solution

Problem

Setting of Jerk

Problem 6: Trolley starts up too slowly 6s (ramp-up=4s, V_max=4216.5mm/s, jerk=600mm/s^3)

Solution: increasing jerk (till V2.0 SP1) or reduce jerk-time (at V2.0 SP2)

Jerk = (maximum_speed/ramp uptime) / Jerk_time

High jerk (2000) shorter jerk_time (0.5s)

Solution


Solution

Problem

Project copy and paste

Problem 7: Copy old application project to use for new project, upgrading with new Crane Libraries, the same function doesn’t work.

Solution: remove the old connections, see attachment

Microsoft Word Document

User Application Project should be updated in certain time

interval by using the standard-application of Simocrane

Basic Technology

Solution


Solution

Problem

Axis Switchover

Problem 8: Axis switchover takes too long time

Solution: Optimizing PLC-Program Change setting of an internal parameter of Sinamics (only for Sinamics FW V2.6), please contact Siemens Cranes

Solution

Thank you
