Retrigger command positioning (3001 and 3002)

The command positioning absolute or relative can be retriggered before the positioning process is completed. During retriggering, the position and speed setpoint can be changed. When positioning absolute, the previous position setpoint is replaced, while positioning relative, the new position setpoint is added to the previous one. Modified speed setpoints have an immediate effect on the movement that is still in progress. Retriggering is possible if the current positioning in status data outDW2 or outDW5 returns the value 1. If the status data outDW2 or outDW5 returns the value 0 it can not be retriggered yet. For retriggering the command must be restarted.
