The pole position identified during the pole position identification is as exact as expected/required.
What happens? The pole position identified during the pole position identification (PPI) significantly deviates from the actual pole position (+/-10°). If necessary, the plausibility monitoring of the PPI will respond.
When does the problem occur? The problem occurs in the case of a pole position identification (PPI) with feedback via Hiperface SinCos absolute value encoder.
Which products are affected? - i700 servo inverter ≤ V01.04.00.9125
Short-term measures/recommendations: None.
Evaluation:
With synchronous motors, large deviations in the pole position information significantly affect the torque generation.
Possibly, the torque required for the application cannot be supplied.
