Electrical installation
4.10 Signal connections
X521 / X531: Encoder connection 2 for HTL/TTL encoder with open-circuit monitoring
Table 4- 50
Max. connectable cross-section: 1.5 mm²
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).
Table 4- 51
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)
