Name

Fault Descriptions

Corrective Actions

Drive’s internal circuitry

abnormal.

1. Switch off power supply.

2. Check whether the input voltage falls within

the rated AC drive input voltage. Switch on

the AC drive.

The external terminal EF-GND

goes from OFF to ON.

When external terminal EF-GND is closed, the

output will be turned off (under N.O. E.F.).

Auto accel/decel failure

Don’t use the function of auto acceleration/

deceleration.

Ground fault :

The AC drive output is abnormal.

When the output terminal is

grounded (short circuit current is

50% more than the AC drive

rated current), the AC drive

power module may be damaged.

The short circuit protection is

provided for AC drive protection,

not user protection.

Ground fault :

1. Check whether the IGBT power module is

damaged.

2. Check for possible poor insulation at the

output line.

Communication Error

Please refer to Pr.92.

1. Check the connection between the AC drive

and computer for loose wires.

2. Check if the communication protocol is

properly set.

External Base Block.

AC drive output is turned off.

1. When the external input terminal (base-block)

is active, the AC drive output will be turned off.

2. Disable this connection and the AC drive will

begin to work again.
