MC_Power_SML (FB)¶

FUNCTION_BLOCK FINAL MC_Power_SML

Controls the power stage of an axis and can be used to issue a quick stop.

Note

The inputs are only processed if Enable is set.
A call of MC_Power_SML with bRegulatorOn=FALSE sets the axis state to PowerOff (disabled).
A call of MC_Power_SML with bRegulatorOn``=``TRUE on a disabled axis sets the axis state to Standstill, if there is no error on the axis. If an error is detected, the state of the axis is set to ErrorStop.
If the inputs Enable, bRegulatorOn and bDriveStart are ``TRUE but the output Status remains in FALSE for a long time, there may be a problem with the power stage, or an external halt may be set.
If power fails (also during operation), the axis state is set to ErrorStop.
