Fault Finding
Problem Possible Cause Remedy
Controller will not
power up - no ‘on’
indication. Wrong supply voltage.
Line fuses blown (if
fitted). Check setting on mains switch.
It is likely that if too high a
voltage has been used the
Controller will be permanently
damaged.
Power off, check circuits and
replace fuses.
Motor will not turn. No run circuit.
No setpoint.
Check run contact and wiring.
Check connections to and
operation of setpoint
potentiometer.
Motor accelerates out
of control with tacho-
generator feedback
and small setpoint. Tacho polarity.
Tacho linkage.
Tacho faulty.
Power off and reverse tacho
connections.
Check tacho coupling to motor.
Remove and replace tacho.
Motor rotates in the
wrong direction.
Speed is controlled
though. Motor connections are
wrong for required
direction with:
1. Armature voltage
feedback.
2. Tacho-generator
Power off and reverse armature
connections.
Power off and reverse both
armature and tacho
connections.
Motor will not turn
and the stall light
comes on after 15
seconds in speed
control mode. Motor shaft locked or
jammed.
No field current (not
applicable for
permanent magnet
motors).
No armature current.
Low current limit.
Power off and check motor and
load for stiffness or jamming.
Check that DC voltage across
motor field terminals is present.
If not power off and check field
circuit for continuity.
Power off and check armature
circuit for continuity.
Check current limit with +10V
link on Controller.
Motor will only run at
full speed.
Maximum speed
setpoint.
Check connections to and
operation of setpoint
potentiometer.
