Fault Descriptions
Communication Error
1
17, 34
Loss of communication with the network
Over Current
2
13, 40, 41, 42, 59
Instantaneous Output Current has exceeded
inverter rated or programmed value
Over Temperature

Heat sink Temperature Limit has been reached
Over Speed Deviation
4
49, 62
Inverter has exceeded maximum or programmed
limit
Over Voltage
5
5, 7, 64
DC Bus Voltage has exceeded inverter limit
Under Voltage
6
1, 6, 8
DC Bus Voltage is lower than required inverter
limit
Short Circuit
7
16
Inverter Output has shorted Phase to Phase
Ground Fault
8
14
Inverter Output Grounding Current has
exceeded manufacturer
Motor Overload
9
10, 50-58, 222
Motor is overloaded
Inverter Overload
10
9
Timed over current fault
Over Torque Detection
11
12
Programmed limit for torque has been exceeded
External Fault
12
142
External fault has been activated in the inverter.
This is a hard fault that must be reset
Operator Interface Error
13
-
Inverter programming or operational interface
malfunction
Load Loss
14
3, 95, 229
Load on the Motor is less than programmed limit
of system. An Example is a broken belt or
coupling
Configuration Error
15
70, 76, 79, 81, 82, 91
Errors exist in the programmed or operational
configuration of the inverter
Feedback Failure
16
60, 90, 192
Required system operational feedback (signal or
sensor) is not responding as expected for correct
system operation
Output Phase Loss
17
30, 31, 32
One or more of the output phases from the
inverter to the motor are open
Motor Stall
18
99
Motor is operating in stall region and not able to
accelerate
Power Unit Error
19
4, 33, 36, 37, 46, 228, 246
Error sensed on the power section of the inverter
Input Phase
20
-
Input single phase or low line voltage condition
Internal Drive Failure
21
23, 27, 38, 39, 47, 48, 73, 85, 86
FC102 specific fault.
