Which products are affected?
ECS axis module ECSxA series, operating system ≤ V6.5
What happens?
A drift of up to 30 Incr/s (= 0.028 rpm) may occur in the quick stop status (QSP).
When does the problem occur?
If QSP is activated without assigning the input for the influence of the phase controller. In case of the application software 'Speed and Torque' this refers to the input 'Speed-MCTRL.PosLim'. When using the MCTRL directly in an own application the input 'MCTRL_nPAdapt_a' is affected.
Possible diagnostics?
Drive diagnostics.
Short-term measures/recommendations?
The influence of the phase controller has to be set to 100 % (= 16384).
Evaluation:
The faulty behaviour does not occur any longer when applying the measure described before.
