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
