Version Information
*1. User unit setting
Positioning and speed units are customizable as user units.
The combination of the system of units (b1,b0) and unit setting bits (b3,b2) give the following settings.
→ For details on the user units, refer to Section 7.10
Note
Motor system units and mechanical system units require pulse/feed rate settings.
*2. The positioning data with position data magnification are as follows:
Example:
The actual address (or travel distance) with target address 1 "123" and position data magnification
"1000" are as follows:
Motor system units: 123 × 1000 = 123000 (pulse)
Mechanical system units, composite system units: 123 × 1000 = 123000 (
µm, mdeg, 10

inch)
= 123 (mm, deg, 10

DOG switch input logic
Sets DOG switch input logic for 20SSC-H.
1: NC-contact (operates at input OFF)
0: NO-contact (operates at input ON)
→For details on the DOG mechanical zero return operation,
refer to Subsection 8.1.2

b13
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.
0: DOG backward end (at ON-to-OFF transition of DOG input)
The back end of DOG triggers the zero-point signal count.
→For details on the DOG mechanical zero return operation,
refer to Subsection 8.1.2
b14 Not available
b15
STOP mode
1: Suspends the operation, and the START command starts the operation for the
remaining travel distance.
0: Ends the operation, canceling the remaining distance. In table operations, operation
is terminated.
→For details on the stop command, refer to Section 7.4
