Inverter setup software

FR-SW

-SETUP-WE

Supports steps from inverter start-up to maintenance. (FR-SW

-

SETUP-WJ is Japanese version.)

Note: 1. "H" in the type code indicates 400V class. Power supply specifications of FR series controllers

and setters: 200VAC 50Hz, 200V/220VAC 60Hz, 115VAC 60Hz.

2. Rated power consumption

3. The intercompatibility attachment (FR-A5AT

……

) is required to mount the inverter, with the

exception of some models.

4. Options available in Japan only.

5. "AT" in the type code indicates an enclosure inside installation structure model and without "AT"

indicates a heatsink outside mounting structure model. For the 37K or more, it can be used in

either way by changing its mounting foot position and does not have "AT" in the type code.
