Speed deviation when operating at constant speed
may fluctuate with characteristics and motor
temperature.
Speed Response 3 Hz (approx.) 10 Hz
Max. frequency of a speed reference signal that the
drive can follow may fluctuate with characteristics
and motor temperature.
Starting Torque 140% at 3 Hz
100% at
5% speed
Starting torque may fluctuate with characteristics and
motor temperature.
Performance may differ by capacity.
Application-
Specific
Auto-Tuning
• Energy Saving Tuning
• Line to line resistance
• Stationary
• Line to line resistance
Automatically adjusts parameter settings that concern
electrical characteristics of the motor.
Speed Search YES YES
Bi-directional speed detection of a coasting motor to
restart it without stopping.
Energy-Saving Control YES –
Saves energy by always operating the motor at its
maximum efficiency.
High Slip Braking YES –
Increases motor loss to allow for faster deceleration.
Effectiveness may vary based on motor
characteristics.
Kinetic Energy Buffering YES YES
Decelerates the drive to allow it to ride through a
momentary power loss and continue operation.
Overexcitation Deceleration YES – Allows faster deceleration without overvoltage trip.
Overvoltage Suppression YES YES
Prevents overvoltage by increasing speed during
regeneration.
