Risk of personal injury or machine damage!
Be careful using this parameter because of the danger of
positive feedback in the position control loop. This will lead to
uncontrolled axis motion at maximum speed.
When you select this parameter, the following warning is generated:
Caution:
Changing this parameter will change the counting direction of the
absolute encoder. Danger of positive feedback!! Make sure the lag
monitoring of your control unit is active.
Diagnosis
To match the servo axis traversing direction to the counting direction in
the machine’s coordinates system, the counting direction of the position
actual value output can be fixed by means of parameters.
