and Maintenance

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

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 B024), 
the inverter trips and turns OFF the output to the 
motor.

––––

Under-voltage (brownout) 
with output shutoff

Due to low input voltage, the inverter turns its 
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 
loss

The inverter is restarting, due to an over-current, 
over-voltage, under-voltage, or a phase loss event. 
See parameter B001 setting in

Expansion card #1
connection error

An error has occurred in an expansion card or at 
its connecting terminals. Please refer to the 
manual for the expansion card for additional 
details.
