FB error: MC_GearShift. Gear shift command is still active, but is commanded again.

Description

This is an error of an instance of the MCV_ShiftGear. The FB was commanded and sets output “Error” to TRUE and displays this error code at the output “ErrorID” in the same PLC cycle, because this FB instance already commanded shift of the gear stage of an axis, but the motion controller hasn't finished up to now the operation of shifting the gear.

Response

Class

-

The job is dismissed by the FB and not issued to the motion controller.

Solution

Class

-

If the error code is displayed, wait until the previous commanded gear stage operation is acknowledged before placing a new job.

In general, it must be prevented that an instance of the MCV_ShiftGear is used to order a gear change as long as a previous gear shift order sent via this FB instance is still active.
