7

The heatsink temperature has risen to or beyond 95°C.

8

Indicates that the motor speed exceeded the overspeed setting value

A

This indicates that the automatic tuning did not complete normally.

B

Indicate that the output current exceeded the thermal operation time

having inverse time characteristics. The standard characteristics are

150% for one minute in respect to the motor rated current. At 155% or

more in respect to the inverter rated current, this will be 170% for 2.5

Fault

Description

Retry

D

(IO-n)

There has been an error in communications through the I/O port.

sub-code

Gate Shutdown Circuit error. A feedback signal has disagreed to

a Gate Shutdown command.

A/D Convertor error. The A/D Convertor has been jammed.

Current Detector Offset. The offset of the Current Detector has

increased to or beyond 0.5V.

Retry time out. Indicates that the operation was not successful

within the No. of retries set in C21-0.

Thermistor fault

Speed detection fault

E

(CPU-n)

There has been an error while the CPU, RAM or ROM is in the self-

diagnosis mode at power-up.

sub-code

Watch-dog error, indicating that the CPU has been jammed.

This fault may appear during at-speed operation.

CPU calculation error.

CPU RAM error.

External RAM error.

E2PROM check-sum error.

E2PROM read error.

E2PROM write error. This error is only displayed, and the gate

will not shut down and FLT will not be output.

Illegal combination of software version and CPU.

F

(dEr)

Indicates that there is an error in the various data stored in the E2PROM.

For details, enter the monitor mode: D20-2, and correct the data.

Caution) If this appears when starting up, the details will not be stored

internally. Thus, after starting up normally, these details

cannot be read with the fault history (D20-0).
