Motor Set-up
E2 constants define motor parameters. Normally, the default settings for E2 constants are
determined by kVA selection (O02-04). In flux vector control and open loop vector, the E2 constants
will be set automatically during auto-tuning. At minimum, the motor rated current should be entered
into E02-01.
If rotational auto-tuning cannot be performed, E02-02 and E02-05 can be calculated using the
motor’s nameplate information or by performing non-rotational auto-tuning.
Motor rated slip frequency (E02-02) can be calculated by using the following equation:
Motor terminal resistance E02-05 can be calculated by using the following equation:
