Table 31. Active Faults
Menu Function Note
Active Faults When a fault/faults appear(s), the display with the name
and fault time of the fault will be pop. Press DETAIL to see
the fault data.
The Active Faults submenu shows the list of faults. Select
the fault and push DETAIL to see the fault data.
The fault remains active until it is cleared with the Reset
button push for 2s) or with a reset signal from the I/O terminal
or Fieldbus.
The memory of active faults can store the maximum of 10 faults in
the order of appearance.
Table 30. History Faults
Menu Function Note
History Faults 10 latest faults are stored in the Fault history, Select the
fault and push
DETAIL to see the fault data.
The history fault will be stored until it is cleared with the
OK button (push for 5s).
The memory of active faults can store the maximum of 10 faults in
the order of appearance.
Step 6 — Faults and Warning Codes
Under this menu, you can find Active faults, History faults and Fault codes.
Fault Codes and Descriptions
Configurable 1 = The fault type of this fault is configurable, fault type can be configured as
0 = No Action; 1 = Warning; 2 = Fault; 3= Fault, Coast
Fault
Code Fault Name Fault Type
Default
Fault Type Possible Cause Remedy Realization
1 Over Current
Fault AC drive has detected too high a current
(>4*IH) in the motor cable:
• Sudden heavy load increase
• Short circuit in motor cables
• Unsuitable motor
• Check loading
• Check motor
• Check cables and connections
• Make identification run
• Check ramp times
DSP
2
Over Voltage Fault The DC-link voltage has exceeded the
limits defined:
• Too short a deceleration time
• Brake chopper is disabled
• High overvoltage spikes in supply
• Start/Stop sequence too fast
• Make deceleration time longer
• Use brake chopper or brake resistor
(available as options)
• Activate overvoltage controller
• Check input voltage
DSP
3
Earth Fault Configurable Fault Current measurement has detected that
the sum of motor phase current is not zero:
• Insulation failure in cables or motor
• Check motor cables and motor DSP
5
Charging Switch Fault The charging switch is open, when the
START command has been given:
• Faulty operation
• Component failure
• Reset the fault and restart
• Should the fault re-occur, contact the
distributor near to you
DSP
6 Emergency Stop Fault Emergency stop input is active from DI Remove signal form DI DSP
7
Saturation Trip Fault • Short circuit in motor cables
• IGBT module is damaged
• Check cables and connections
• Reset the fault and restart
• Verify that EMC screw is installed
• Should the fault re-occur, contact the
distributor near to you
DSP
9
UnderVoltage Configurable Fault DC link voltage is under the voltage limits
defined:
• Most probable cause: Too low a supply voltage
• AC drive internal fault
• Defect input fuse
• External charge switch not closed
Note: This fault is activated only if the drive is in
Run state.
• In case of temporary supply voltage
break reset the fault and restart the
AC drive Check the supply voltage.
If it is adequate, an internal failure
has occurred. Contact the distributor
near you
DSP
10 Input Phase
Superv
Configurable Fault Input line phase is missing • Check supply voltage, fuses
and cable
