Which products are affected?
9300EP servo positioning controller version V2.1
What happens?
An incorrect home position is determined in some cases.
When does the problem occur?
With homing modes 4 and 5 with encoder or Sin/Cos encoder as position sensor an incorrect home position was determined in some cases if during homing an zero pulse had occurred and the home position was then calculated from it internally.
Possible diagnostics?
Drive is sporadically in the wrong position after homing.
Short-term measures/recommendations?
Use a different homing mode.
Evaluation:
Uncritical in practice because modes 4 and 5 are seldom used and there are other modes available.
