Which products are affected?
9300EP servo positioning controller version V2.1
What happens?
The current reference measuring offset C1220/7 cannot be reset to the value selected under C1225 by using the homing function.
When does the problem occur?
Use of the function 'Set position value' brings about an intentional shifting of the current reference measuring offset C1220/7 in relation to the value defined under C1225. By executing a homing procedure it was, however, not possible to reset this shifting back again.
Possible diagnostics?
The current reference measuring offset (C1220/7) differs from the input value under C1225, even after homing.
Short-term measures/recommendations?
Before homing, execute the 'Set home position' function.
Evaluation:
Not critical because a work-around is possible if the 'Set position value' function is used, see above. In practice the offset shifting tends to be used seldom with this function.
