When either one of the variable speed drives or frequency 
converters in the machine experience a fault and “trip” out, 
they will cease to run and an error message will appear 
fl ashing on the keypad display (see picture below).

The following list are the most commonly experienced faults 
and possible action steps.

1—OVER CURRENT

Motor being worked too hard and 
drawing extra current.

Check current being drawn when machine is 
running. Reduce speed setting and current draw 
back into acceptable limits as described on 
previous page.

Short circuit on output side of vari-
able speed drives or frequency con-
verters.

Check wiring in plugs connected to motor cables 
or inside connection boxes on motors.

Motor failure (very rare)

Have motor tested and replace if required.

Poor voltage supply to machine will 
result in excess current draw

See comments on page 10

3—EARTH FAULT

Short circuit on output side of vari-
able speed drives or frequency con-
verters.

Check wiring in plugs connected to motor cables 
or inside connection boxes on motors.

Motor failure (very rare)

Have motor tested and replace if required.

9—UNDER VOLTAGE

Insuffi cient voltage supply to ma-
chine.

Check power supply and ensure correct voltage.

Power supply to variable speed 
drives or frequency converters has 
been turned off.

Re-connect power to grinder.

11—OUTPUT PHASE

SUPERVISION

Short circuit on output side of vari-
able speed drives or frequency con-
verters.

Check wiring in plugs connected to motor cables 
or inside connection boxes on motors.

Motor failure (very rare)

Have motor tested and replace if required.

14—UNIT OVER TEM-
PERATURE

Variable speed drives or frequency 
converter over temperature due to 
high temperature working environ-
ment or faulty temperature sensor.

Open door on electrical cabinet to increase ven-
tilation. Have variable speed drives or frequency 
converter tested by service agent.

15—MOTOR STALLED

Motor being worked too hard and 
drawing extra current.

Check current being drawn when machine is 
running. Reduce speed setting and current draw 
back into acceptable limits as described on 
previous page.

Mechanical jam preventing motor 
from turning.

Try rotating grinding discs and planetary head by 
hand to see if jam exists

16 - MOTOR OVER TEM-
PERATURE

Motor being worked too hard and 
drawing extra current.

Check current being drawn when machine is 
running. Reduce speed setting and current draw 
back into acceptable limits as described on 
previous page.
