MCV_Couple
With the MCV_Couple FB an axis may be recoupled, i.e. it will be reactivated., e.g. after decoupling to replace a motor. The sequence of the internally commanded FBs is shown in the flow chart below.

| VAR_IN_OUT | ||
| Variable name | Data type | Description | 
| Axis | AXIS_REF | Axis reference | 
| VAR_INPUT | ||
| Variable name | Data type | Description | 
| Execute | BOOL | The axis coupling sequence is triggered on a rising edge. | 
| MotorIndex | UDINT | The value at this input determines which parameter set is activated when an axis is coupled. Axes can therefore be coupled to different drive motors. | 
| VAR_OUTPUT | ||
| Variable name | Data type | Description | 
| Done | BOOL | The axis was coupled successfully. | 
| Error | BOOL | Indicates TRUE if an error occurs in the FB. | 
| ErrorID | WORD | Error code |
