Table positioning - Actual position is not updated in case of mains off (remedied from V2.01 onwards)

Remedied from:
8400 HighLine   SW V2.01 onwards

Behaviour of the new version?
The above-named software version rectifies this functional restriction.




Which products are affected?
8400 HighLine   SW ≤ V2.00

What happens?
If the power voltage of the frequency inverter is switched off (external 24V supply still available) and the drive is moved manually, the current actual position (L-C01210/3) is not updated.  As a result, the drive loses its reference to the home position. This leads to a faulty position result.

When does the problem occur?
The problem always occurs if the drive is moved while the power voltage (external 24V supply still available) is switched off.

Possible diagnostics?
Observe the current actual position (L-C01210/3) while the power voltage is switched off.

Short-term measures/recommendations?
Execute homing after every mains switching.

Evaluation:
This behaviour is usually detected during commissioning.
