12 Troubleshooting
E035 Thermistor Error
If an abnormal temperature is observed during detection of resistor level change in an external thermis-
tor, the inverter turns OFF its output. (When thermistor function is enabled.)
Occurrence
Motor is heated.
Motor is not heated.
E036 Brake Error
This error occurs when the inverter can not detect whether the brake check signal is ON or OFF during
waiting time after the inverter has output a brake releasing signal. (When brake function is enabled.)
Occurrence
Error occurred after
operation.
E038 Low-speed Range Overload Error
This error occurs to protect the main element if the inverter has output at a low frequency of 0.2 Hz or
below.
When such a low frequency is detected by the built-in electronic thermal function, the inverter turns
OFF its output.
Occurrence
Error occurred
during output at low
speed.
