Calibration
REGULATION (IR COMP)
The IR COMP setting determines the degree to which motor
speed is held constant as the motor load changes. It is factory set
for optimum motor regulation. Recalibrate the IR COMP setting
when using a lower horsepower motor. Refer to the recommended
IR COMP settings on page 25, or recalibrate using the following
procedure:
If the motor does not maintain set speed as the load changes,
gradually rotate the IR COMP trimpot CW. If the motor oscillates
(overcompensation), the IR COMP trimpot may be set too high
(CW). Turn the IR COMP trimpot CCW to stabilize the drive.
The IR COMP trimpot setting determines the degree to which
motor speed is held constant as the motor load changes. It is
factory set for optimum motor regulation.
To calibrate IR COMP (exact calibration):
1. Turn the IR COMP trimpot full CCW.
2. Set the speed adjust potentiometer until the motor runs at
midspeed without load (for example, 900 RPM for an 1800
RPM motor) A hand held tachometer may be used to measure
motor speed.
3. Load the motor armature to its full load armature current
rating. The motor should slow down.
4. While keeping the load on the motor, rotate the IR COMP
trimpot until the motor runs at the speed measured in step 2.
