Invert the angular incremental encoder input (from
SW 3.5)
75 – x PosStw.7
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:
Angular incremental encoder interface as input refer to Chapter 6.8.2
The signal may only change when the axis is stationary.
Reference cams 78 – x PosStw.2
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 79 x x –
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
Starting in front of or at the cam and
traversing in a positive direction ––> the 1/0
edge at input I0.x is identified as equivalent
zero mark
Starting after the cam and traversing in a
negative direction ––> the 0/1 edge at input I0.x
is identified as the equivalent zero mark
