T1-08 encoder). Set the number of

without a multiplication factor.

电流 = 4).
* 1. Not normally displayed. Displayed only when a motor switch command is set for a multi-function digital input (one of H1-01 to H1-10 set to 16).
* 2. The factory setting depends on the Inverter capacity. Values are given for a 200 V Class, 0.4 kW Inverter.
* 3. The setting range is from 10% to 200% of the Inverter rated output current. The value for a 200 V Class Inverter for a 0.4 kW is given.
* 4. 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.
* 5. For fixed output motors, set the base speed value.
* 6. For Inverter motors or for specialized vector motors, the voltage or frequency may be lower than for general-purpose motors. Always confirm the infor-
mation on the nameplate or in test reports. If the no-load values are known, input the no-load voltage in T1-03 and the no-load current in T1-05 to
ensure accuracy.
* 7. The settings that will ensure stable vector control are between 50% and 100% of the Inverter rating.
* 8. Refer to Chapter 8 Procedure for Adjusting Constants after Replacement of Control Board (Page 8-3) for the details of setting 3 (Shipping adjustment).
* 9. 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.
Refer to page 3-15 for Digital Operator displays during autotuning.
Precautions for Precision Settings
Settings for autotuning are different when performing autotuning using motor test reports or design data. Use
