Motor Set-up
E2 constants define motor parameters. Normally, the default settings for E2 constants are determined
by KVA selection (O02.04). In open loop vector control the E2 constants will be set automatically
during auto-tuning. If the control method is V/f (A01.02 = 00), the motor rated current should be
entered into E02.01.
If auto-tuning cannot be performed, some E2 constants can be calculated using the motor’s
nameplate information.
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:
