Note
Operation of unipolar HTL encoders
When unipolar HTL encoders are used, A*, B*, and R* on the terminal block must be
jumpered with M_Encoder (X531).

Max. connectable cross-section: 1.5 mm²
Measuring current via temperature sensor connection: 2 mA
Accuracy of the temperature measurement:
1)
- KTY: ±7 °C (including evaluation)
- PT1000: ±5 °C (PT1000 tolerance class B according to EN 60751 including evaluation)
- PTC: ±5 °C (including evaluation)
Danger to life due to electric shock in the event of voltage flashovers at the temperature
sensor
Voltage flashovers in the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
• Only use temperature sensors that fully comply with the specifications of the safety
