Integrated temperature evaluation

Information for the connection of an
external temperature sensor• The external temperature sensor mustcomply with the following prerequisites
as per EN 61800-5-1:– Voltage class A– Contamination level 2– Overvoltage category 3• Only connect passive temperaturesensors• The connections for the temperature
sensor are galvanically connected withthe encoder electronics.
• Depending on the application, thetemperature sensor assembly (sensor+ cable assembly) is to be mountedwith double or reinforced insulationfrom the environment.
• Accuracy of temperature measurement
depends on the temperature range.
• Comply with tolerance of thetemperature sensor• The transmitted temperature value is nota safe value in the sense of functionalsafety• The motor manufacturer is responsible
for the quality and accuracy of thetemperature sensor, as well as for
ensuring that electrical safety ismaintained• Use a crimp connector with a suitabletemperature range (e.g. up to +150 °C
ID 1148157-01)

Connectable temperature sensors
The temperature evaluation within
the rotary encoder is designed for aKTY 84-130 PTC thermistor.

The table shows the relationship between
the output value and the resistance of thetemperature sensor.
For the KTY 84-130, the temperature value
equals the output value. The value unit is
1 kelvin.
