6.16.5 Interpolator
The interpolator operates at the clock rate defined in MP_ipoCycle. The axis-
specific nominal position values are calculated at this clock rate from the feed
rate profiles transferred by look-ahead.
MP_ipoCycle
Cycle time of position controller (interpolation clock pulse)
Format: Selection menu
Selection: 3 ms
At this time only a position controller cycle time of 3 ms is
supported. Therefore no other values can be selected.
Default: 3 ms
Access: LEVEL3
Reaction: RESET
