G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
Ironless Linear Motors have one PTC thermistor in its Motor Coil Unit.
This PTC thermistor has a characteristic that the resistance increases suddenly at around 110
º
C.
Utilize this characteristic to build a circuit to stop the motor in case of overheating.
Be sure to build a circuit that detects overheating at a resistance at around 90
º
C to 100
º
C, so that the
maximum coil temperature 110
º
C allowed for the Motor Coil Unit is not exceeded.
Ironless Linear Motors also have another NTC thermistor for measuring the average Motor Coil Unit
temperature.

PTC
Note 1
The resistance value in a low temperature range is approximately 50
Ω
.
2
The resistance value increases gradually when the temperature is at over 90ºC.
3
The temperature detected by a PTC thermistor has an error of approximately ±10ºC. Take this error into
account and use the motor at or lower than the maximum temperature allowed for the Motor Coil Unit. The
upper limit temperature is 110ºC.

Note
The temperature value has an error of ±7 to ±10ºC.
