After the homing run has been completed, Bit 11 STW must be set to 0 again.

Alternatively, the reference point can also be set at the actual position.
This can be achieved by setting Bit 12 STW, or by setting the homing run Type 0 with parameter
1350 and subsequent start of the homing run by Bit 11 STW .
