MC_GearOut_BkPlcMc (from V3.0)
The function block releases a coupling between two axes. This coupling must have been established with an MC_GearIn_BkPlcMc or an MC_GearInPos_BkPlcMc function block.

Behavior of the function block
On a rising edge at Execute the function block checks the transferred axis interface. A number of problems can be detected and reported during this process:
- If the axis is not operated in a gear coupling, the function block immediately indicates Done and omits all further checks or activities.
- If the current set velocity of the axis is smaller than the velocity specified by pStAxParams.fCreepSpeed, the axis immediately assumes McState_Standstill and dissipates the residual velocity. Done is indicated, and no further checks or activities take place.
If these checks could be performed without problem and Done is not already indicated for one of the reasons mentioned, the motion controlled by the gear coupling is converted to a continuous motion with the same velocity and direction, which is independent of the master. Done is indicated if this conversion was executed successfully, otherwise the system responds with Error and ErrorID:=error code.
