Supported motor
types
Asynchronous motor (ASM), also known as induction motor (IM). Synchronous motor (SM), which typically
is permanent magnet synchronous motor (PMSM).
Supported speed

0 Hz
–
Approximately 200% of the motor nominal
speed, or 320 Hz.
Estimation error
–
ASM: < 50% of nominal slip.

SM: Esti-
mated speed = actual speed.
ASM: Approximately ± 50% of nominal slip.

Speed estimation
active
Speed estimation is active only when the AC drive is in RUN state.

With an asynchronous motor, the estimation is typically less reliable at low speeds and more reliable at high speeds.
The effects of external accelerative forces are not taken into account in the values above. The values are valid in these conditions:
The motor parameters have been set correctly, and the motor identification run has been completed successfully.
The motor is not overloaded.
