Motor Temperature Input

The traction motor's temperature sensor input measures the resistance of the connected sensor. The
controller supports KTY8x, and PT1000 temperature sensors. A parameter-VCL sensor configuration
profile allows the usage of custom solutions, with a maximum source current of less than 2 mA. The
controller is unable to use low resistance sensors, such as the PT100.
In all cases, connect the sensor's ground/negative lead to the controller's I/O ground.

Table 17 Motor Temperature Sensor Specifications

1 LOS Mode: 100°C in case of sensor failure.
±5°C full range temperature accuracy.
2
3 ±15°C for 24V F2-A, ±5°C for other models.
When using custom sensors, note that maximum resistance measurement range supported in default configuration is 4k Ohms.
4
Temperature sense accuracy does not apply to custom sensors.
Custom sensor setup is via VCL. Consult Curtis.
