Note
Motor system units and mechanical system units require pulse/feed rate settings.
*2. The positioning data with position data magnification are as follows:
- Mechanical zero-point address
- Software limit (upper)
- Software limit (lower)
- Target address1
- Target address2
Example:
The actual address (or travel distance) with target address 1 "123" and position data magnification
"1000" are as follows:

DOG switch input logic
Sets DOG switch input logic for 20SSC-H.
1: NC-contact (operates at input OFF)
b12
0: NO-contact (operates at input ON)
Count start timing for zero-phase signal
1: DOG forward end (at OFF-to-ON transition of DOG input)
The front end of DOG triggers the zero-phase signal count.
b13 0: DOG backward end (at ON-to-OFF transition of DOG input)
The back end of DOG triggers the zero-point signal count.
