Setting Motor Constants: E2-01 to E2-09
The motor constants (function E2) will all be set automatically when autotuning is performed.
Set these constants manually if autotuning can’t be completed properly.

The setting range is 10% to 200% of the Inverter rated output current. The default setting depends upon
the Inverter capacity. (The table shows the default setting for 400-V class, 200 kW Inverters.) See page
8 - 42.)

D
Calculate the rated slip (E2-02) from the value shown on the motor nameplate with the following equa-
tion and set this value.
Rated slip = rated frequency (Hz) -- rated speed (r/min) × number of poles/120
