Positioning Parameters

The positioning parameters to set speed and units of measurement.
The BFMs in positioning parameters are readable/writable.
It is necessary to change the positioning parameters enable command (BFM #519/619 b4) from OFF to ON
when changing positioning parameters during operation. Changing the positioning parameters enable
command must be done during stop in order for the changes to become valid.
→ For details on the Positioning parameters enable command, refer to Subsection 11.4.11
For X-axis: BFM #14000 to #14199
For Y-axis: BFM #14200 to #14399
Caution
Do not use unlisted BFMs for changing values not described in this section.

Zero return direction
1: In zero return, starts operation toward the increasing current value direction.
b10
0: In zero return, starts operation toward the decreasing current value direction.
→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)
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.
