VACON 100 FAULT CODES
(ABRIDGED)
Fault Code Fault ID Fault Name Possible Cause How to correct the fault
1 1 Overcurrent
(hardware fault)
Current draw is too high a (>4*I H) in the motor
cable. The possible cause can be one of these:
 a sudden heavy load increase
 short circuit in the motor windings

motor is not the correct type
 parameter settings are not properly
made
Check the VFD loading. Check of the
motor, check of the cables and
connections.
Perform a test run.
Set the acceleration time longer, if
required.
2 Overcurrent
(software fault)
2 10 Overvoltage
(hardware fault)
The DC-link voltage is higher than the limits.
 Deceleration time id too short

There are high overvoltage spikes in
the supply
Check the input voltage(s).
Set the deceleration time longer.
Activate the overvoltage controller.
11 Overvoltage
(software fault)
3 20 Earth fault
(hardware fault)
The VFD has detected that that the sum of the
motor-phase-current is not zero

An insulation malfunction in the
cables or in the motor.

A filter (du/dt, sinus) malfunction
Check the motor cables and the motor.
Check the filter.
21 Earth fault
(software fault)
8 600 System Fault There is no communication between the control
board and the power.
Reset the fault and restart the drive. If
the fault re-occurs again, contact the
Vacon distributor.
601
602 Defective component operation malfunction
603 The voltage of auxiliary power in the power unit
is too low.
604 Output phase voltage does not agree with the
reference. Feedback fault
605 Operation malfunction
606 Software of control unit is not compatible with
software of power unit
607 The software version cannot be read. There is no
software in the power unit. Defective
component. Operation malfunction (power
board or measurement board).
608 A CPU overload
609 Defective component. Operation malfunction Reset the fault and power cycle the VFD
twice. ( power off, power on)
