L_MC1P: Synchronous motor with brake: If the pollage setting is different, the inverter cannot be disabled via xEnableOperation=FALSE (fixed from V03.32.00)
Removed from:
Library: L_MC1P_MotionControlBasic (FAST Motion) as of V03.32.00
Behavior of the new version:
When using the brake logic in motion control, the behavior when locking is now as follows: After the request to disable the inverter (xEnableOperation = False), now immediately after execution of the quick stop ramp, the brake is activated to engage and the inverter is disabled. The standstill detected on the basis of the actual speed is no longer waited for in order to ensure that the brake is applied at a "sensible" time even if the pollage setting is different.
Descriptionof the behavior: After the request to disable the inverter (xEnableOperation = False), the inverter first executes a quick stop (QSP) via the brake logic. The inverter is only actually disabled after the quick stop ramp has elapsed and the actual speed has reached standstill. However, Due to the principle it is not possible to shut down the synchronous motor in a controlled manner if the pollage setting is significantly different. In consequence, the inverter is not locked and the holding brake does not engage either.
Conditions under which the behavior occurs:
brake logic in motion control
synchronous motor and
pollage setting deviates significantly from the correct setting and
the inverter should be disabled (xEnableOperation = False).
