No value for MCTRL_dnActIncLastScan in case of splitted feedback (remedied from B-SW V7.4)

Remedied from:
ECS axis module V7.4

Behaviour of new version?
When homing to zero pulse, the correct value is output at MCTRL_dnActIncLastScan after the zero pulse occurred.



Which products are concerned?
ECS axis module V7.1 and lower

Problem description:
When homing to zero pulse, no value is output at MCTRL_dnActIncLastScan after occurrence of the zero pulse. The home position thus is only reached with some deviation.

When does the problem occur?
When setting C0490 = encoder (position feedback), C0495 = resolver (speed feedback) and C0911 = master pulse and homing to zero pulse.

Possible diagnostics?
Indication of the value MCTRL_dnActIncLastScan.

Short-term measures/recommendations?
None.

Evaluation
This homing mode involves a certain inaccuracy. After homing, there are no restrictions concerning the operation of the system.
