E23

Gate array error

An internal inverter error has occurred in commu-

 

 

 

nications between the CPU and gate array IC.

 

 

 

 

 

 

 

 

 

 

 

E24

Phase failure detection

One of three lines of the 3-phase power is missing.

 

 

 

 

 

 

 

 

 

 

 

 

E30

IGBT error

When an instantaneous over-current condition

 

 

 

occurs on any IGBT (output transistor) device, the

 

 

 

 

 

 

 

 

inverter alarm trips. then it turns the outputs OFF

 

 

 

 

in order to protect the circuitry.

 

 

 

 

 

 

 

E35

Thermistor

When a thermistor is connected to terminals [TH]

 

 

 

and [CM1] and the inverter has sensed the temper-

 

 

 

 

 

 

 

 

ature is too high, the inverter trips and turns OFF

 

 

 

 

the output.

 

 

 

 

 

 

 

E36

Brake error

When the inverter releases the brake and cannot

 

 

 

detect whether the external brake is ON or OFF

 

 

 

 

 

 

 

 

within the waiting time (set by parameter B124),

 

 

 

 

the inverter trips and turns OFF the output to the

 

 

 

 

motor.

 

 

 

 

 

 

 

––––

Under-voltage (brownout)

Due to low input voltage, the inverter turns its

 

 

with output shutoff

output OFF and tries to restart. If it fails to restart,

 

 

 

 

 

 

 

then the alarm trips to record the under-voltage

 

 

 

 

error event.

 

 

 

 

 

 

 

 

Automatic restart and phase

The inverter is restarting, due to an over-current,

 

 

 

loss

over-voltage, under-voltage, or a phase loss event.

 

 

 

 

See parameter B001 setting in “Automatic Restart

 

 

 

 

Mode and Phase Loss” on page 3–29.

 

 

 

 

 

 

 

E6X

Expansion card #1

An error has occurred in an expansion card or at

 

 

connection error

its connecting terminals. Please refer to the

NOTE: If an EEPROM error (E08) occurs, be sure to confirm the parameter data values are still correct.
