4.9 Additional connections
X521 / X531: Encoder connection 2 for HTL/TTL/SSI encoder with open-circuit monitoring
Table 4- 61
Connector
Max. connectable cross-section: #16 AWG (1.5 mm²)
Note
Operation of unipolar HTL encoders
When unipolar HTL encoders are deployed, A*, B*, and R* must be jumpered on the terminal
block with M encoder (X531).
Table 4- 62
Connector
Max. connectable cross-section: #16 AWG (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)
