6.4 PG Feedback Connection
The pulse input signals are connected to terminal block TB1. Table 3 provides terminal descriptions for
terminal block TB1. PGA1 and PGA2 are connected for Phase A, PGB1 and PGB2 are connected for
Phase B, and PGZ1 and PGZ2 are connected for Phase Z. The wiring for Phase Z is done only when
using a Z-marker is necessary. The polarity of the pulse input signals should be as follows:
+ Side: PGA1, PGB1, PGZ1
- Side: PGA2, PGB2, PGZ2
