Connector type: 15-pin Sub-D socket
Measuring current via temperature sensor connection: 2 mA
1) Accuracy of the temperature measurement:
- KTY: ±7 °C (including evaluation)
- PT1000: ±5 °C (PT1000 tolerance class B according to DIN EN 60751 including evaluation)
- PTC: ±5 °C (including evaluation)
NOTICE
Damage to the encoder due to incorrect supply voltage
The encoder supply can be parameterized to 5 V or 24 V. Incorrect parameter assignment
can cause damage to the encoder.
• Select the appropriate supply voltage.
NOTICE
Damage to motor in the event of incorrectly connected KTY temperature sensor
If a KTY temperature sensor is connected with incorrect polarity, it is not possible to detect
when the motor overheats. Overheating can cause damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
