Position of the machine datum
Position given with respect to scale reference
point. For encoders with distance-coded
reference marks, with respect to the zero
reference mark.
For EnDat encoders, relative to the absolute
encoder datum.
Format: Numerical value
Input: –100 000.0 to + 100 000.0 [mm]
Default: 100.0 [mm]

Active level of the trip dog for reference end
position
Format: Selection menu
Input:
 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

(optional parameter)
Referencing with external reference signal
Format: Selection menu
Input:
 Off:
The reference signal of the connected motor
encoder or the position encoder is used.
 spindleRef (X30):
On systems with HSCI, the reference signal at
–SP.REF+ and –SP.REF– of the external PL is
evaluated; on systems with MC 320 or MC 42x
the reference signal at input X30 is evaluated.
Default: Off
