Motor pulse usage
This monitoring watches over the duration of the defined pulse current. The
permitted duration for the pulse current is defined by the pulse current time
constant.
If the acceleration current exceeds the nominal current for a defined time t1, a
sufficient break time t2 is required. If the current remains in average above the
nominal current, the "monitoring motor pulse usage" [0x7180] error is triggered.
Upon a high pulse usage, the error will occur almost without delay.
