High-function General-purpose Inverter RX2 Series User’s Manual
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.)
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.)
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.
E035 Thermistor Error
Occurrence
Estimated cause(s)
Exemplar measures to be taken
Motor is heated.
The motor hasn’t been
cooled sufficiently.
The cooling environment needs to be improved.
Heavy load has been
applied for a long time.
The motor’s driving environment needs to be re-examined.
Motor is not heated.
Inadequate thermistor
function setting
Re-examination of the thermistor function setting may improve
the situation.
The thermistor is broken
down.
The thermistor needs to be repaired.
Malfunction due to noise
The situation may be improved by taking a noise countermea-
sure such as wiring separation.
E036 Brake Error
Occurrence
Estimated cause(s)
Exemplar measures to be taken
Error occurred after
operation.
Disconnection of signal
line.
Check the wiring of brake check signal and whether the signal
is ON or OFF.
Brake function setting
The situation may be improved by re-examination of brake
check waiting time or input terminal logics according to the
sequence of the signal.
E038 Low-speed Range Overload Error
Occurrence
Estimated cause(s)
Exemplar measures to be taken
Error occurred
during output at low
speed.
The motor load is heavy.
Load at low-speed range needs to be reduced. If the error
occurs frequently, you need to select an inverter with a capac-
ity large enough for the motor.
