Troubleshooting

Symptom

Possible

Causes

Suggested

Solutions

Motor runs too slow
or too fast

Motor will not reach
the desired speed

1. Voltage switches

set incorrectly.
(NOTE: This
does not apply to
XL1100A drives.)

2. MIN SPD and

MAX SPD not
calibrated.

3. Motor field not

properly
connected (shunt
wound motors
only).

1. MAX SPD setting

is too low.

3. IR COMP setting

is too low.

3. Motor is

overloaded.

1. Verify all switch

settings.

2. Calibrate MIN

SPD and MAX
SPD.

3. Verify motor field

connections.

1. Increase MAX

SPD setting.

2. Increase the IR

COMP setting.

3. Check motor load.

Resize the motor
or drive if
necessary.
