  1. Important Points in SIMOCRANE Engineering and Commissioning Dr. Qing Chen Product Management Siemens Cranes

  2. Overview V2.0 SP2 has default setting to aviod problem 1&2 Problem • Problems: • Simotion CPU goes to Stop • frequent encoder error or TO-error • Invert-ready signal comes and goes • PLC-control does not work • Too long time for axis switchover • Trolley’s reaction is too slow • Project doesn’t work after copy and paste • Axis switchover takes too long time

  3. 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 Task-Configuration Setting

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

  5. Problem 2: frequent TO-error Solution: expert listconfiguration data, set ‘TypeOfAxis_DriveControlConfig_pulsesEnabled_bitNumber’ to 11 'TypeOfAxis_DriveControlConfig_pulsesEnabled_pzdNumber  to 4 'TypeOfAxis_DriveControlConfig_releaseDisableMode to 7 TO-Configuration setting (2) Solution

  6. Problem 2: frequent TO error Solution: expert listconfiguration data, set 'RestartCondition.restartAxisCondition’ to NO_CONSTAINTS TO-Configuration setting (3) Solution

  7. Problem 2: frequent TO error Solution: expert listconfiguration data, set 'Restart.behaviorInvalidSysvarAccess’ to DEFAULT_VALUE TO-Configuration setting (4) Solution

  8. Problem 3: Invert-ready signal comes and goes Solution: Setting Load gear / Measureing gear / Leadscrew pitch TO-Mechanics Setting Solution Leadscrw pitch = diameter of wheel / drum * π

  9. Problem 3: Invert-ready signal comes and goes Solution: Following error Deactivated at beginning Setting at the end of commissioning TO-Monitoring Setting (1) Solution

  10. Problem 3: Invert-ready signal comes and goes Positioning and Standstill TO-Monitoring Setting (2) Solution

  11. 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 PLC-program

  12. 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) Setting of Jerk Solution

  13. 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 Project copy and paste Solution • User Application Project should be updated in certain time • intervalby using the standard-application of Simocrane • Basic Technology

  14. 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 Axis Switchover Solution
