WF2 Fault Codes
Table 29 shows the fault codes that may be displayed, along with suggestions for recovering from the fault condition.
Fault
Code
Fault Name
Possible Cause(s)
How to Recover
01
Watch Dog Trip
Contact BERGES for further information. Contact BERGES for further information.
02
Power Bridge Id
•
•
Ribbon cable not correctly seated be- •
tween the power and control boards.
Electrical noise.
•
Ensure that the ribbon cable is correctly
seated.
Determine the source of the noise and
eliminate it.
03
Current Calibr
Current sensors have an offset problem.
Contact BERGES for further information.
04
TSP 24V Supply
Overloaded +24 V DC supply.
Check the loading on the +24 V DC supply
and remove any excess load.
05
DC Volt Calibr
DC voltage is outside of normal limits on •
•
power-up. This may be caused by:
• High or low line voltage.
• Supply Voltage parameter incorrectly
set.
Check line voltage.
Check the Supply Voltage parameter
(see page 106).
06
IOC Trip
Output short-circuit. May also be caused •
by a ground fault (see Fault Code 11 be- •
•
low).
•
Check motor wiring.
Extend acceleration ramp.
Reduce boost.
Check for ground faults.
07
Ext Flt/Warning
(Fault)
The configured input sensed an external
fault.
Investigate why the external fault occurred
and correct.
09
Inter-Proc Comm
Loss of communication with the control
terminal strip.
Reset the drive by pressing the Stop key
for more than 1 second. If problem persists, consult BERGES.
11
Ground Fault
The drive detected that the sum of the mo- •
tor phases’ current is not zero. This may •
be caused by insulation failure in the mo•
tor or the cables.
12
Input Phase Loss
Current measurement detected an input
phase with no current.
13
Overvoltage
The voltage of the internal DC-link has ex- •
ceeded 135% of the nominal voltage. This •
may be caused by incorrect deceleration
time or high overvoltage spikes on line.
14
Under Voltage
The DC bus voltage fell below 65% of the
nominal voltage. This may be due to line
supply failure or internal failure of the
drive.
Reset fault and attempt to restart. Check
the line for proper supply. If fault persists,
an internal fault has occurred; contact
BERGES.
15
DB Crct Failure
The dynamic brake (DB) is overloaded.
•
•
•
Check motor wiring.
Check for and remove any capacitive
load.
Check the motor and cabling for shorts
to ground.
Check input power cables.
Adjust deceleration time.
Add dynamic braking module.
Check for an open DB resistor.
Check for a shorted DB transistor.
Consult BERGES.
