AUTOTUNE
SETUP::MOTOR CONTROL::AUTOTUNE
Designed for SENSORLESS VEC and CLOSED-LOOP VEC Motor Control Modes.
The autotune is an automatic test sequence performed by the Drive to identify motor model parameters. The motor model is
used by the Sensorless Vector and Closed-Loop Vector control modes. You MUST perform an autotune before operating the
Drive in either of the Vector control modes.
Refer to the Chapter 4/5: The Autotune Feature.
Parameter Descriptions
ENABLE
PREF: 80.01 Default: FALSE Range: FALSE / TRUE
Determines whether the Autotune sequence is operational or not. The Autotune sequence is operational when set to TRUE and
the Drive is run. Refer to Chapter 4/5: The Autotune Feature.
MODE
PREF: 80.02 Default: ROTATING Range: See below
Selects the Autotune operating mode. Refer to Chapter 4/5: - The Autotune Feature.
Enumerated Value : Mode
0 : STATIONARY determine motor parameters
1 : ROTATING determine motor parameters
2 : SPD LOOP ROTATING determine speed loop tuning dependent on motor inertia
3 : SPD LOOP STATIONARY determine speed loop tuning dependent on motor inertia
