EPC-PG16 User Manual
When differential output encoder (5V power supply) is used for
speed feedback, please select twin-cloosed-loop PG board
EPC-PG16 as an optional board. In addition, EPC-PG16
supports two differential output encoders for speed feedback
simultaneously; and it supports O/A, O/B, O/Z three-channel
frequency dividingoutput, and output typeis differential.

3.1 CN3 Wiring Instruction
Power supply and signal cables should be twin-twisted and then
be connected according to Fig. 2, details:
Pin 13 and 12 cable should be twin-twisted
Pin 9 and 4 cable should be twin-twisted
Pin 10 and 5 cable should be twin-twisted
Pin 15 and 14 cable should be twin-twisted
Pin 6 and 1 cable should be twin-twisted
Pin 7 and 11 cable should be twin-twisted
Pin 2 and 8 cable should be twin-twisted
The shielded layer of entire cable shall be reliably connected to
metal shell of DB plug.
