iPOS4803-SY Multi Axis System, EtherCAT Technical Reference
3.8 Feedback connections
3.8.1 Feedback #1 - Single-ended Incremental Encoder Connection
Figure 9
Feedback #1 - Single-ended Incremental Encoder Connection for iPOS4803-SY
CAUTION!
DO NOT CONNECT UNTERMINATED WIRES TO PINS J3#x.9, J3#x.13 AND J3#x.17.
THEY MIGHT PICK UP UNWANTED NOISE AND GIVE FALSE ENCODER
READINGS.
Encoder cable shield must be connected to system GND to avoid disturbances /
noise induced by nearby cables.
3.8.2 Feedback #1 - Differential Incremental Encoder Connection
Figure 10
Feedback #1 - Differential Incremental Encoder Connection for iPOS4803-SY
Remarks:
1. For iPOS4803-SY Multi Axis System Feedback
#1 differential connection, 120Ω (0.25W)
termination resistors
are internally added by putting the SW1#x pins 1,2 and 3 on “ON” position.
2. 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.
