X521 / X531: Encoder connection 2 for HTL/TTL/SSI encoder with open-circuit monitoring
Table 4- 49 Encoder connection X521
Terminal Signal name Technical specifications
1 A Incremental signal A
2 A* Inverted incremental signal A
3 B Incremental signal B
4 B* Inverted incremental signal B
5 R Reference signal R
6 R* Inverted reference signal R
7 CTRL Control signal
8 M Ground via inductivity
Max. connectable cross-section: 1.5 mm²
Note
When unipolar HTL encoders are used, A*, B*, and R* on the terminal block must be
jumpered with M_Encoder (X531).
