Sets the maximum torque for the motor to
YES
protect the load and connected machinery.
Allows direct control of motor torque for
YES
tension control and other such applications.
Sets the slip for the load torque of the
YES
motor. Used for motor load distribution.
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.
Increases motor loss to allow for faster
deceleration than normal without the use of
N/A
a braking resistor. The effectiveness may
vary based on motor characteristics.
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 increasing speed
YES during regeneration. Never use this
function with hoist or crane applications.
Greatly increases the speed control range
N/A
of an IPM motor.
