Automatically
adjusts parameter
settings that concern
electrical
characteristics of the
motor.
Torque Limit N/A N/A YES YES N/A YES YES
Sets the maximum
torque for the motor
to protect the load
and connected
machinery.
Torque Control N/A N/A N/A YES N/A N/A YES
Allows direct
control of motor
torque for tension
control and other
such applications.
Droop Function N/A N/A N/A YES N/A N/A YES –
Zero Servo
Control
N/A N/A N/A YES N/A N/A YES
Locks the rotor
position.
Application-
Specific
Speed Search YES YES YES – YES YES YES
Bi-directional speed
detection of a
coasting motor to
restart it without
stopping.
Energy-Saving
Control
YES YES YES YES N/A
YES
(IPM motors
only)
YES
(IPM motors
only)
Saves energy by
always operating the
motor at its
maximum
efficiency.
High Slip
Braking
YES YES N/A N/A N/A N/A N/A
Increases motor loss
to allow for faster
deceleration than
normal without a
braking resistor.
Effectiveness may
vary based on motor
characteristics.
Feed Forward
Control
N/A N/A N/A YES N/A N/A YES
Improves speed
accuracy when the
load changes by
compensating
effects of the system
inertia.
Kinetic Energy
Buffering
YES YES YES YES YES YES YES
Decelerates the
drive to allow it to
ride through a
momentary power
loss and continue
operation.
Over-
excitation
Deceleration
YES YES YES YES N/A N/A N/A
Provides fast
deceleration without
using a braking
resistor.
Inertia Tuning,
ASR Tuning
N/A N/A N/A YES N/A N/A YES
Provides automatic
Speed Control and
Feed Forward
function tuning.
Overvoltage
Suppression
YES YES YES YES YES YES YES
Prevents
overvoltage by
increasing speed
during regeneration.
Never use this
function with hoist
or crane
applications.
High Frequency
Injection
N/A N/A N/A N/A N/A YES N/A
Greatly increases the
speed control range
of an IPM motor.
