AKM52K temperature sensor
Hi again all at KM
Again, I am with American GFM, machine tool builder of high speed ultrasonic cutting machines.
We are starting a new machine where 2 of its axes are using AKM52K-ANCNR-00 motors.
I am trying to configure the temperature sensor in Workbench.
Can anyone tell me which type of sensor is in this motor?
The only choice that works in the "Motor Temperature" screen is code #1 NTC
But all documentation I see says AKM2-7 motors use PTC sensors.
The thermal resistance is < 100 ohms, it does not seem to change much as the motor heats up.
We ran the axis aggressively today and the motor got very hot.
Measured with the thermal camera showed it to be 65 deg C
The ohms value at that temperature was 58 ohms (according to WB).
After the motor cooled down to room temperature, it only rose to 62 ohms (according to WB).
Also, what is the maximum temperature of this motor?
