Eliminated from:
PLC Designer V3.6
L_SM3_DriveUtil library V3.6
Behaviour of the new version:
If control-guided homing is started before the starting operation of the axis is completed, the L_SMC_Home function block sends an error message.
What happens?
Control-guided homing with the L_SMC_Home function block is not executed.
When does the problem occur?
If control-guided homing is started before the starting operation of the axis is completed (e.g. directly after switching on the axis), homing is not executed.
If the starting operation of the axis is completed (xAxisEnable=TRUE), homing can be started after recalling the L_SMC_Home FB.
Which products are concerned?
PLC Designer from V3.3
L_SM3_DriveUtil library V3.3
Possible diagnostics:
The axis does not execute homing. The function block output xDone does not become TRUE.
Short-term measures/recommendations:
Only start homing if the xAxisEnabled status signal of the axis is TRUE.
Evaluation:
Homing is not executed if it is started before the axis is enabled.
