Inputs—High-Speed/Auxiliary Encoder
The high-speed inputs are optically isolated inputs. Current is limited internally for input voltage control of 5 to 24
volt logic. The Anode (+) and Cathode (−) optocoupler inputs are on separate connector pins to allow significant
flexibility in wiring to different styles of interface.

Note: All parameters are at the connector pin.
Here are some additional notes regarding the use of the high-speed inputs:
 Two high-speed inputs can be wired as an encoder input:
 A+/A- are wired to high speed input 5
 B+/B- are wired to high speed input 6
 The encoder 5V power source is available on the IO connector.
 Differential encoder signals are used.
 The controller always reads as both inputs and as an encoder.
 No software selection/command is required.
 The encoder input is mapped to controller parameter ENC1 (P6160).
 The encoder position value can be utilized for gearing, cam, etc.
 ENC1 can also be assigned as a position feedback source.
