Note 1. The setting units for parameters E1-04, E1-06, and E1-09 can be changed.
Note 2. This function is specific to flux vector control.
H Setting Motor Parameters
The motor parameters (function E2) will all be set automatically when auto-tuning is performed, so it
normally
isn’t necessary to set them manually
. Set these parameters manually if auto-tuning can’t be
completed properly. These parameters cannot be changed during operation.
Set the rated current (A) shown on the motor’s nameplate.

Rated slip = rated frequency (Hz) – rated speed (r/min) × number of poles/120
Set
the no-load current (E2-03) at the rated voltage and rated frequency
. Normally this value isn’t shown
on the motor’s nameplate, so it might be necessary to contact the motor manufacturer.

Set the motor’s terminal resistance between U and V, V and W, or W and U.
Usually
the nameplate of the motor does not provide the motor
’
s terminal resistance. Contact the motor
manufacturer for a test report on the motor’s terminal resistance to set the following values.
• Type E insulation: Motor’s terminal resistance (Ω) at 75°C x 0.92
• Type B insulation: Motor’s terminal resistance (Ω) at 75°C x 0.92
