Peak currents during operation (remedied from B-SW V6.6)

Remedied from:
ECS axis module B-SW  V6.6

Behaviour of new version?
Short, partially audible peak currents at the motor do not occur any longer.


Which products are affected?
ECS axis module B-SW ≤ V6.5

What happens?
Short, partially audible current pulses at the motor

When does the problem occur?
The behaviour may already occur when the controller is enabled and is increased by high current gain factors (C0075).

Possible diagnostics?
None.

Short-term measures/recommendations?
None.

Evaluation:
The audible noises can be traced back to a faulty actual current calculation.
