Sets the maximum torque for the motor to

protect the load and connected machinery.
Allows direct control of motor torque for
YES
tension control and other such applications.
YES Locks the rotor position.
Bi-directional speed detection of a coasting
YES
motor to restart it without stopping.
YES (IPM Saves energy by always operating the
motors only) motor at its maximum efficiency.
Improves speed accuracy when the load
YES changes by compensating effects of the
system inertia.
Decelerates the drive to allow it to ride
YES through a momentary power loss and
continue operation.
Provides fast deceleration without using a
N/A
braking resistor.
Provides automatic Speed Control and
YES
Feed Forward function tuning.
Prevents overvoltage by reducing
regenerative torque in application where
constant speed is not required.
Note: The drive cannot reduce
YES
regenerative torque when using the V/f
Control mode. Instead try increasing the
frequency level to avoid overvoltage in V/f
Control.
Greatly increases the speed control range
N/A
of an IPM motor.
The Disturb Function changes the
N/A
frequency reference in periodic intervals.
