This parameter defines the time after which, when approaching the position, the following error
must be within the standstill window (P0326).
Note:
The standstill monitoring time is rounded–off in the drive to an integer multiple of the posi-
tion controller clock cycle (P1009).
If a larger value is entered in P0325 than in P0320, this is limited internally in the drive to
P0320.

This parameter defines the standstill window, within which the position actual value must be
located after the standstill monitoring time has expired (P0325).

There are the following differences between the standstill and positio-
ning monitoring:
Standstill monitoring (zero–speed monitoring)
After the standstill monitoring time has expired, the system cycli-
cally checks whether the axis remains within the standstill window
around the target position.
Objective: Continually checks that the position is maintained
Positioning monitoring
For this monitoring function, after the positioning monitoring time
has expired, it is checked once whether the actual position lies
within the positioning window around the target position.
Objective: Single check as to whether the position has been
reached with sufficient accuracy
