IR COMPENSATION
(P.206)
Sets the armature
voltage loss
compensation value
used when the drive
is configured as a
voltage regulator.
Parameter Range:
0 to 50%
Default Setting:
0%
Parameter Type:
Tunabl e
This parameter is also used by the Field Current Regulator kit to set the
field-weakened threshold.
IR COMPENSATION
is normally determined from the motor data sheet. It should be
set to the percent
IR
drop of the motor.
If this data is not available on the motor data sheet, you can set this empirically so
that the no-load and full-load speeds are as close as possible when operating as a
voltage regulator.
This parameter is not available for current/torque regulated drives.
MOTOR HOT FLD AMPS
(P.510)
This parameter only
needs to be set if the
Field Current
Regulator kit is
installed.
Parameter Range:
0.11 to installed supply rating (4.00, 10.00, or 20.00
amps)
Default Setting:
0.01 amps
Parameter Type:
Configurable
Motor nameplate value of the rated hot field amps. This input is the basis of field
current scaling.
If the factory defaults are restored, or if a valid value has not yet been entered for
this parameter, the DC field voltage is fixed at 150V on a 230VAC line, or at 300V
on a 460VAC line.
!
ATTENTION:
You must configure this to the motor nameplate value. The
incorrect configuration of this parameter can cause a motor overvoltage
condition. Configure
MOTOR HOT FLD AMPS
to the motor’s nameplate
value. Failure to observe this precaution can result in bodily injury and
damage to the equipment.
