Troubleshooting

SPEEDMASTER™ OPERATION MANUAL

Symptom

Possible

Causes

Suggested

Solutions

Motor pulsates or
surges under load

On non-reversing
drives, motor runs in
the opposite
direction

Motor will not stop
when the speed
adjust potentiometer
or reference signal
is set to zero speed.

1. IR COMP is set too

high.

2. Control is in current

limit mode.

1. Motor armature leads

are reversed.

1. MIN SPD trimpot is

not adjusted properly.

1. Adjust the IR COMP

setting slightly CCW
until the motor
speed stabilizes
(page 13).

2. Check that motor is

of sufficient
horsepower and
amperage.

1. Reverse connections

to the motor
armature.

1. Slowly rotate the

MIN SPD trimpot
until the motor
stops.
