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

!

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.

Parameter Range:

100 to 690 volts

Default Setting:

460

Parameter Type:

Configurable
