If the motor nameplate shows the no load current data, then this parameter value can
be calculated using the following formula. If this data does not appear on the motor
nameplate, perform the self-tuning procedure (U.008) to automatically calculate the
result.

Magnetizing Current = No Load Amps x 100
Motor Rated Amps

Important: This parameter must be set prior to activating the torque control

self-tuning operation (U.008).

If you change this parameter after performing self-tuning using parameter U.008, you
must repeat the self-tuning procedure.

U.006 Magnetizing Current

This parameter
identifies the
percentage of
magnetizing current
(no load amps) with
respect to motor
rated amps.

A value is
automatically
generated for this
parameter when
self-tuning is
performed (U.008).

Parameter Range:

10.0 to 80.0%

Default Setting:

Power Module-dependent, see Appendix C

Parameter Type:

Configurable

U.008 Torque Self-Tune Enable

ATTENTION: If this parameter is set incorrectly, overcurrent or excess
heating of the motor could result. Failure to observe this precaution could
result in damage to, or destruction of, the equipment.

U.007 Motor Nameplate Volts

This parameter
identifies motor rated
voltage as it appears
on the motor
nameplate.
