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.
