MC_GearOut

MC_GearOut 1:

The function block MC_GearOut deactivates a linear master-slave coupling (gear coupling).

Note: If a slave axis is disconnected in motion, it is not stopped automatically, but it reaches a constant speed with which it continues to move endlessly. The axis can be stopped with a stop command. (see also MC_GearOutExt)

Notice

Migrating to TwinCAT 2.11

If the Set Point Generator Type is set to '7 Phases (optimized)', the slave axis will reduce its acceleration to zero after it is being decoupled and it will then continue moving endless at constant velocity. The decoupled axis will not be positioned to any target position.
The behavior is comparable to a move commanded by MC_MoveVelocity.
With TwinCAT 2.10 the set point generator type is selectable.
From TwinCAT 2.11 the setting is fixed to '7 Phases (optimized)'.
If a project is upgraded from TwinCAT 2.10 to TwinCAT 2.11, the behavior will be as described here. After updating an existing application to TwinCAT 2.11, it might be necessary to adapt the PLC program.
