Note 2. The setting range and factory setting for n31 (electronic thermal reference cur-
rent) depend on the Inverter model. For details, refer to page 4-19.
Normally, set the rated motor amperage in n31.
Note 3. The setting range for the 400-VAC models is “1 to 5.”
Note 4. The factory setting for the 3G3EV-A4015-CUE is “3.”
Note 5. Displaying the constant no. corresponding to an indicator in the “Dedicated
indicator” column lights the indicator.
Note 6. Constant no. 02 (n02) and subsequent constants can be set only when
constant no. 01 (n01) is set to 1.
Constants in the shaded areas in the above table may not be usable depending on the
PROM number (software version).

Only n01 can be set.
Constants n01 to n68 can be displayed and set.
All constants are returned to factory settings.
The Inverter is initialized in 3-wire sequence mode.
Note 1. If other constants are to be set, always set “1” in n01.
Note 2. Setting “9” (3-wire sequence mode) in n01 allows the user to start and stop the
Inverter with automatic recovery type push-button switches.
