Signal name, description
Invert the angular incremental encoder input (from
SW 3.5)
The incremental position reference value, received via the angular incremental encoder interface, can be
inverted using this input signal. When inverting, the incremental position reference value becomes effec-
tive in the opposite direction.
1 signal Inverting the incremental position reference value via the angular incremental encoder
interface
0 signal No inversion
Note:
S
Angular incremental encoder interface as input
S
The signal may only change when the axis is stationary.
Reference cams
This input signal is used to signal, when referencing, whether the axis remains stationary at the reference
cam.
1 signal The axis is located at the reference cam
0 signal The axis is not located at the reference cam
Equivalent zero mark
If the encoder zero pulse cannot be evaluated when referencing, then a signal supplied from a mounted
sensor can be fed via this input as "zero mark equivalent".
1 signal No significance
1/0 signal When passing the zero mark cam in a positive direction, this edge is detected as the
equivalent zero mark
0/1 signal When passing the zero mark cam in a negative direction, this edge is detected as the
equivalent zero mark
0 signal No significance
Assumption:
The BERO is high active

Starting in front of or at the cam and
traversing in a positive direction ––> the 1/0

Starting at the cam and traversing in a
negative direction ––> an equivalent zero

mark is not identified
Starting after the cam and traversing in a
negative direction ––> the 0/1 edge at input I0.x
