MOTOR INDUCTION

SETUP::MOTOR CONTROL::MOTOR INDUCTION

Designed for all Motor Control Mode, except PMAC Control Mode.

In this function block you enter the details of the motor under control and any available motor nameplate information.

The Autotune feature will determine the MAG CURRENT, STATOR RES, LEAKAGE INDUC, MUTUAL INDUC and ROTOR

TIME CONST motor model parameter.

The OVERLOAD parameter determines the allowed level of motor overload. This can be especially useful when operating

with motors smaller than the drive rating.

Note Do not attempt to control motors whose rated current is less than 25% of the drive rated current. Poor motor control

or Autotune problems may occur if you do.
