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. Applicable for Control Boards ETC618046-S1033 and later. Refer to
Chapter 8
Procedure for Adjusting Constants after Replacement of Control Board
(Page 8-4) 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. Applicable for G7-Series Inverters with software versions PRG 1039 and later.
* 8. 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.
