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

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

Problem
TO-Configuration setting (1)
Problem 2: frequent encoder error
Solution: expert listconfiguration data, set 'TypeOfAxis.NumberOfEncoders.Encoder_1.SensorControlConfig.tolerateSensorDefect’ to YES

Problem
TO-Configuration setting (2)
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
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
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
