201 [Drive Type Sel]
Important: This parameter is only applicable to non-regenerative (2-
quadrant) drives.
Allows non-regenerative drives to use an external 4-quadrant controller.
• “On” = Ramp, Speed, Torque current references and Speed measurement
have the same behavior as a four quadrant drive.

374 [Drv Fld Brdg Cur]
Drive rated field bridge current (I

equal to the value chosen with DIP switch S14 on the control board (see
Tab le 15 on page 61 for DIP switch configuration). Leave set to the default
value for permanent magnet motor applications.

376 [MtrOvrld Type]
Allows selection of the type of motor overload calculation based on Par 179
[Motor Arm Amps].
• StandardDuty = 150% load for 1 minute or 200% load for 3 seconds
before a motor overload condition is indicated.
• HeavyDuty = 200% load for 1 minute before a motor overload condition
is indicated (250% for 30 sec). This selection requires that the drive be
oversized relative to the motor in order to be able to provide the necessary
current without faulting from a “Drive Overload” (F.64).
Note: This parameter was added for firmware version 3.001.

464 [SAR Volts Scale]
Scales the following parameters so that they show actual voltage values
rather than drive calculated values when in Standalone Regulator (SAR)
mode:
Notes: This parameter was added for firmware version 4.001. See Appendix H
PowerFlex DC Standalone Regulator Installation on page 349
for more
information.
Important: When the drive is not in SAR mode, this parameter is clamped to
the default value (1.0).
