6 TROUBLESHOOTING

6.1 FAULT DETECTION

When the power regenerative unit detects a fault, the fault code is displayed on the
LED monitor, the fault contact output operates.

S

When a fault has occurred, refer to the following table to identify and cor-
rect the cause of the fault.

S

Reset the fault after restarting the power regenerative unit by turning ON
the fault reset signal or turning the main circuit power supply of and then
on again.

Power Regenerative Unit Input

Overload

Power regenerative unit input ex-

ceeded the overload capacity.

The load is too heavy.

Check the size of the load.

Heatsink Overheating

The temperature of the power re-

The ambient temperature is too

high.

Install a cooling unit.

The power regenerative unit’s

cooling fan has stopped.

Replace the cooling fan. (Contact

our sales representative.)

Main Circuit Undervoltage

The main circuit DC voltage is be-

low the undervoltage detection

level.

200 V class : Approx. 190 VDC

400 V class : Approx. 380 VDC

S

An open-phase occurred with

the input power supply.

S

A momentary power loss oc-

curred.

S

The wiring terminals for the in-

put power supply are loose.

S

The voltage fluctuations in the

input power supply are too

large.

Reset the fault after correcting its

cause.

Control Power Fault

The control power supply voltage

dropped.

S

Try turning the power supply off

and on.

S

Replace the power regenerative

unit if the fault continues to oc-

cur.

Inrush Prevention Circuit Fault

A fault occurred in the inrush pre-

vention circuit.
