Pole position identification 'PPI at standstill' does not detect motor phase failure (corrected from V01.03.07)

Corrected from:
i950 servo inverter FW:   from V01.03.07.1252
 
Response of the new version:
From now on an interruption of a motor phase will be monitored also with pole position identification via "PPI at standstill".
This monitoring function is independent from the other motor phase phaliure monitoring function, which can be parameterised via 0x2D45:x.
 
 
What happens?
In the case of an interrupted motor phase, pole position identification via "PPI at standstill" leads to a non-deterministic result.
In this case, the "PPI at standstill" identification run may be aborted with an error message or a pole position may be identified that does not correspond to the correct pole position.
A faulty pole position may lead to an unexpected drive behaviour.
 
When does this behaviour occur?
The behaviour occurs when identifying the pole position via "PPI at standstill", when a motor phase is interrupted.
 
Which products are affected?
i950 servo inverter FW
(i700 servo inverter)

Short-term measures / Evaluation / Recommendations:
Activate the motor phase failure monitoring function (0x2D45).
If a motor phase failure is detected, remove the failure and repeat "PPI at standstill".
