(50) Braking Resistor Protection Selection (Sn-65)
•Sn-65= 0 : External braking resistor protection invalid
= 1 : External braking resistor protection valid
•Whenever the external braking resistor is used, be sure that the parameter ‘Sn-65 =
1’ is set.
(51) Motor Parameter Autotuning Selection (Sn-66)
•The AUTOTUNE feature can be used to identify and store the motor’s parameters
•Sn-66= 0 : Autotuning Disable
= 1 : Autotuning Enable
(52) Control Mode Selection (Sn-67)
•Select one of the two control modes
•Sn-67= 0 : V/F Control Mode (include V/F control with PG feedback)
= 1 : Sensorless Vector Control Mode
Sensorless Control
*1 *2
1. Set Sn-67 = 1 for sensorless vector control.
2. Set Sn-66 = 1 for autotuning.
*1. Sensorless Vector Control will be available soon in all UL type 7200MA
inverters.
*2. For output frequency less than 1.5Hz in sensorless vector control, set Sn-02=15
and then change Cn-07 to required frequency.
