Drive Start Up
10. With the “Motor Data” group selected, press Enter and configure the
following parameters:
Note: Parameters 45 [Max Ref Speed] and 162 [Max Feedback Spd] are
typically set to the motor nameplate base speed. However, if a speed
feedback device is used (encoder or tachometer), see Drive Reference
and Feedback Scaling on page 269 for details on setting these
parameters.
❏ 45 [Max Ref Speed] - Enter the motor nameplate base speed.
❏ 162 [Max Feedback Spd] - Enter the motor nameplate base speed.
❏ 175 [Rated Motor Volt] - Enter the rated motor nameplate
armature voltage. This value should be the measured armature
voltage when the motor is running at base speed with rated field
current. This value should represent 100% of the rated armature
voltage when field weakening is not used. If field weakening is used,
this value should be set to 90% of the rated armature voltage to
prevent a possible overvoltage condition when the drive transitions
to the field weakening mode.
❏ 179 [Nom Mtr Arm Amps] - Enter the rated motor nameplate
armature current.
❏ 374 [Drv Fld Brdg Cur] - Enter the rated current of the field bridge
regulator to match the value set using the DIP switch S14. See Field
Current Configuration on page 54.
❏ 280 [Nom Mtr Fld Amps] - Enter the rated motor nameplate field
current. If using a permanent magnet motor, leave this parameter set
to the default value.
