The αi series servo motor contains thermistors instead of thermostats
contained in conventional models. This function can receive thermistor
data and convert it to a temperature (°C) to provide ”motor temperature”
information.
The αi servo motor has two thermistors: one for detecting the motor
winding temperature and the other for detecting the pulse coder
temperature. When the motor winding temperature reaches 140°C or the
temperature of the printed circuit board in the pulse coder reaches 100°C,
a motor overheat alarm is issued.
3520 Servo motor temperature information
[Data type] Integer axis
[Unit of data] °C
Displays the temperature of the winding of the αi servo motor. When the
temperature reaches 140°C, a motor overheat alarm is issued.
NOTE
The temperature at which an overheat alarm is issued may
have an error of up to 5°C.
