Cause : Incorrect pole position identification comes when problem encountered in control systems or signal processing, where the poles of a system are not accurately identified. Poles are critical parameters in characterizing the behavior of systems, especially in stability analysis and controller design.

A fault has occurred during the pole position identification routine.

Fault value (r0949, interpret decimal):
1: Current controller limited
2: Motor shaft locked.
10: Stage 1: The ratio between the measured current and zero current is too low.
11: Stage 2: The ratio between the measured current and zero current is too low.
12: Stage 1: The maximum current was exceeded.
13: Stage 2: The maximum current was exceeded.
14: Current difference to determine the +d axis too low.
15: Second harmonic too low.
16: Drive converter too small for the measuring technique.
17: Abort due to pulse inhibit.
18: First harmonic too low.
20: Pole position identification requested with the motor shaft rotating and activated "flying restart" function.

For fault value = 1: Check whether the motor is correctly connected. Check whether motor data have been correctly entered. Replace the power unit involved.

For fault value = 2: Bring the motor into a no-load condition.

For fault value = 10: When selecting p1980 = 4: Increase the value for p0325. When selecting p1980 = 1: Increase the value for p0329. Check whether the motor is correctly connected. Replace the power unit involved.

For fault value = 11: Increase the value for p0329. Check whether the motor is correctly connected. Replace the power unit involved.

For fault value = 12: When selecting p1980 = 4: Reduce the value for p0325. When selecting p1980 = 1: Reduce the value for p0329. Check whether motor data have been correctly entered.

For fault value = 13: Reduce the value for p0329. Check whether motor data have been correctly entered.
