Zero return direction
1: In zero return, starts operation toward the direction increasing current value.
b10
0: In zero return, starts operation toward the direction decreasing current value.
→For details on the zero return operation, refer to Section 8.1
Acceleration/deceleration mode
1: Operates in approximate S-shaped acceleration/deceleration.
b11 (Trapezoidal ACC/DEC in interpolations)
0: Operates in trapezoidal acceleration/deceleration.
→For details on the acceleration/deceleration mode, refer to Section 7.2
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)
A front end of DOG triggers the zero-phase signal count.
b13 0: DOG backward end (at on-to-off transition of DOG input)
A back end of DOG triggers the zero-point signal count.
