Ke parameter for a Permanent Magnet Motor
Default: 0
Settings 0–65535 (Unit: V/krpm)
Ke parameter of a permanent magnet motor (V
phase, rms
/ krpm).
When Pr.05-00=5, the induction electromotive force Ke is measured according to the motor’s
actual operation.
When Pr.05-00=13, the Ke is automatically calculated according to the motor power, current and
rotor speed.
