Figure 33
Feedback #1 - Differential Incremental Encoder Connection for iPOS4803S
Remarks:
1. For iPOS4803P and iPOS4803PE Feedback#1 differential connection, 12
0Ω
(0.25W) terminators must be
connected for long encoder cables, or noisy environments.
2. For iPOS4803S Feedback #1 differential connection, 12
0Ω (0.25W) terminators
are internally added by
putting the SW1 pins 1,2 and 3 on “ON” p
osition.
3. The length of the cables must be up to 30m, reducing the exposure to voltage surges in industrial
environment.
CAUTION!
Encoder cable shield must be connected to system GND to avoid
disturbances / noise induced by nearby cables.
