Fault Diagnosis and Corrective Actions
(From Yaskawa inverter handbook)

Fault Display Description Details Corrective Action

Uv 1 Main circuit under-voltage Under-voltage in the direct current main circuit during running
200V class: Approx. 190V or less
400V class: Approx. 380V or less
- Check the power supply wiring
- Correct the line voltage

Uv 2 Control circuit under-voltage Under-voltage in the control circuit during running

Uv 3 MC fault The pre-charge contactor opened during running

oC Over-current The inverter output current exceeded the OC level - Check the motor coil resistance
- Extend the accel/decel time
- Check the motor insulation
Multi-meter check

ov Over-voltage The main circuit direct current voltage exceeded the OV level
200V class: Approx. 400V or less
400V class: Approx. 800V or less
Extend the deceleration time, add braking circuit

GF Grounding (Earth) Fault Inverter output grounding current exceeded 50% of inverter rated current - Check the motor insulation has not deteriorated
- Check the connection between inverter and motor is not damaged

PUF Main circuit fault - The direct current circuit fuse is blown
- The output transistor is damaged
Check for damaged transistor, load side short circuit, grounding etc.

oH 1 Heat-sink overheat The transistor heat-sink temperature exceeded the allowable value Check the fan and ambient temperature

oH 2 Heat-sink overheat The transistor heat-sink temperature exceeded the allowable value

oL 1 Motor overload Inverter output exceeded the motor overload level Reduce the load

oL 2 Inverter overload Inverter output exceeded the motor overload level Reduce the load, extend the acceleration time

oL 3 Over-torque detection Inverter output current exceeded the over-torque detection level

S C Load short-circuit Inverter output is short-circuited - Check the motor coil resistance
- Check the motor insulation

EF 0 External fault from serial communication Fault occurs in the external control circuit Check the external control circuit

EF 2 External fault at terminal S2 Fault occurs in the external control circuit Check the condition of the input terminal. If the LED lights up when terminal is not connected, replace the inverter.

EF 3 Ext. fault at terminal S3

EF 4 Ext. fault at terminal S4

EF 5 Ext. fault at terminal S5

EF 6 Ext. fault at terminal S6

SP 1 Excessive ripple in bus bar - Inverter input power supply has open-phase
-large unbalance in input voltage
- Check the line voltage
- Re-tighten the input terminal screws

SP o Output open phase Inverter input power supply has open-phase - Check the output wiring
- Check the motor impedence
- Re-tighten the input terminal screws

CE MODBUS transmission fault Control data cannot be received normally Check the transmission device or signal

CPF 0 Control circuit fault 1 (Digital operator transmission fault) Transmission between inverter and digital operator cannot be established 5 seconds after supplying power (initial) - Insert the digital operator connector again
- Check the control circuit wiring
- Replace the control card

CPF 1 Control circuit fault 2 (Digital operator transmission fault) Transmission between inverter and digital operator is established once after supplying power, but later transmission fault continues for more than 2 seconds (online)

CPF 4 EEPROM fault Inverter control unit fault Replace the control card

CPF 5 CPU A/D converter fault
