T: Motor Autotuning
The following settings are made with the motor autotuning constants (T constants): Settings for autotuning.
* 1. Set T1-02 and T1-04 when 2 is set for T1-01. Only set value 2 is possible for V/f control or V/f control with PG.
* 2. These are values for a 200 V Class Inverter. Values for a 400 V Class Inverter are double.
* 3. The factory setting depends on the Inverter capacity. The value for a 200 V Class Inverter for 0.4 kW is given.
* 4. The setting range is from 10% to 200% of the Inverter rated output current. The value for a 200 V Class Inverter for 0.4 kW is given.
* 5. Refer to Chapter 8 Procedure for Adjusting Constants after Replacement of Control Board (Page 8-3) for the details of setting 3 (Shipping adjustment).
* 6. When the control method is changed, the factory setting will change. The open-loop vector 1 control factory setting is given.
* 7. The setting range depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given. The upper limit depends on the setting of
E2-01.
