6.1  Fault Detection

6.1

Fault Detection

When the power regenerative unit detects a fault, the fault code is displayed on the Digital Operator and the fault contact output operates.
When a fault has occurred, refer to the following table to identify and correct the cause of the fault.
Use one of the following methods to reset the fault after restarting the power regenerative unit.

• Turn ON the fault reset signal.

• Press the RESET Key on the Digital Operator.

• Turn the main circuit power supply OFF and then ON again.

Table 6.1  Fault Displays and Processing

Fault Display

Meaning

Probable Causes

Corrective Actions

PUF
IGBT, Fuse Failure

Fuse Blown
The fuse in the main circuit is blown.
The main transistor has damaged.

The output transistor has failed because 
of a short-circuit or overcurrent.

Replace the power regenerative unit 
after correcting the cause.

UV1
Dc Bus Undervolt

Main Circuit Undervoltage
The main circuit DC voltage is below 
the undervoltage detection level 
(L2-05).
200 V class: Approx. 190 VDC 
400 V class: Approx. 380 VDC

• An open-phase occurred with the 

input power supply.

• A momentary power loss occurred.
• The wiring terminals for the input 

power supply are loose.

Reset the fault after correcting its cause.

UV2
CTR PS Undervolt

Control Power Fault
The control power supply voltage 
dropped.

—

• Try turning the power supply off and 

on.

• Replace the power regenerative unit if 

the fault continues to occur.

UV3
MC Answerback

Inrush Prevention Circuit Fault
A fault occurred in the inrush 
prevention circuit.

—

• Try turning the power supply off and 

on.

• Replace the power regenerative unit if 

the fault continues to occur.

AUv
Ac Undervoltage

AC Power Undervoltage
AC power undervoltage occurred 
during running.
200 V class: Approx. 150 VAC or less
400 V class: Approx. 300 VAC or less

• An open-phase occurred with the 

input power supply.

• A momentary power loss occurred.
• The wiring terminals for the input 

power supply are loose.

Reset the fault after correcting its cause.

FdVe
Power F Fault

Power Supply Frequency Fault
AC power supply frequency has 
exceeded the setting value (F1-10).

• The power supply fluctuations 

occurred during running.

• Power loss occurred during running.

Reset the fault after correcting its cause.

SrC
Power Supply Flt.

Power Supply Fault
The phase of the input power supply has 
changed after turning ON the control 
power supply.

• An open-phase occurred with the 

input power supply.

• A momentary power loss occurred.
• The wiring terminals for the input 

power supply are loose.

Reset the fault after correcting its cause.

OC
Over Current

Overcurrent
The output current of the power 
regenerative unit exceeded the 
overcurrent detection level.
(200% of rated current)

• A short-circuit occurred at the power 

regenerative output.

• Power supply drop
• Faulty wiring

Reset the fault after correcting its cause.

SC
Short Circuit

IGBT Short-circuit
The IGBT gate signal was short-
circuited.

A short-circuit of the PWM signal 
occurred.

Replace the control card.

OV
Dc Bus Overvolt

Main Circuit Overvoltage
The main circuit DC voltage exceeded 
the overvoltage detection level.
200 V class: Approx. 400 VDC 
400 V class: Approx. 800 VDC

The deceleration time is too short and 
the regenerative energy from the motor 
is too large.

• Increase the deceleration time.
• Check the capacity of the power 

regenerative unit.

• (Increase the capacity.)

The power supply voltage is too high.

Decrease the voltage so it is within 
specifications.

OH
Heatsink Overtmp

Heatsink Overheating
The temperature of the power 
regenerative unit’s cooling fins 
exceeded the setting in L8-02.
(Stopping method can be changed by 
L8-03.)

The ambient temperature is too high.

Install a cooling unit.

There is a heat source nearby.

Remove the heat source.

The cooling fan of the power 
regenerative unit has stopped.

Replace the cooling fan. (Contact our 
sales representative.)

OH1
Heatsink Max temp

Heatsink Overheating
The temperature of the power 
regenerative unit’s cooling fins 
exceeded 105°C.
(Stopping method: Coast to stop)

The ambient temperature is too high.

Install a cooling unit.

There is a heat source nearby.

Remove the heat source.

The cooling fan of the power 
regenerative unit has stopped.

Replace the cooling fan. (Contact our 
sales representative.)
