Direction and
velocity
In MP_refDirection you specify the direction of traverse. If the axis traverses
the reference-end-position trip dog, and PP_AxReferenceEndPosition is set,
the direction of traverse is reversed.
In MP_refFeedHigh and MP_refFeedLow, define the velocity for traversing
the reference marks.
It depends on the entry in MP_refType whether the low or high reference-run
velocity is used.
MP_refDirection
Direction for traversing the reference marks

The parameter MP_refSwitchActive defines the status of the trip dog for
reference end position.
MP_refSwitchActive
Active level of the trip dog for reference end position
Available from NCK software version: 597 110-01.
Format: Selection menu
Selection: high
Reference-end-position trip dog is active if
PP_AxReferenceEndPosition = 1
low
Reference-end-position trip dog is active if
PP_AxReferenceEndPosition = 0
Default: high
Access: LEVEL3
Reaction: REF
