Command generation axis speed change request: CHGVS
■Usable Data
: Usable
■Description, data type of result
• A speed change is made shown below.
1. The "[St.346] Command generation axis speed change accepting flag (R: M36751+32n/Q: M9811+20n)" corresponding
to the axis specified with (S1) is turned ON.
2. The speed of the axis specified with (S1) is changed to the speed specified with (S2).
3. The speed change accepting flag is turned OFF.
• The axis No. that may be set at (S1) is within the following range.
• For interpolation control, set any one of the interpolation axes to (S1). When linear interpolation control is exercised, a
speed change varies as described below with the positioning speed designation method set in the servo program.
• Operation varies with the sign of the specified speed set at (S2).

Positioning speed designation method Operation
Vector speed designation Speed change is made so that the vector speed becomes the speed specified with (S2).
Longest axis designation Speed change is made so that the longest axis speed becomes the speed specified with (S2).
Reference axis speed designation Speed change is made so that the reference axis speed becomes the speed specified with (S2).
Sign of specified speed Operation
Positive Speed change
0 Temporary stop
