5 OPERATION CONTROL PROGRAMS
(3) 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.
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).
(4) Operation varies with the sign of the specified speed set at (S2).
Sign of specified speed Operation
Positive Speed change
0 Temporary stop
Negative Return
(5) The specified speed that may be set at (S2) is within the following range.

(6) The speed changed by CHGVS instruction is effective only on the servo program
during starting.
(7) The speed change does not executed for the axis specified with (S1) during
deceleration stop.
(8) Acceleration/deceleration time at speed change can be changed by setting the
acceleration/deceleration time change parameter of the axis specified by (S1).
Refer to the "Q173DSCPU/Q172DSCPU Motion controller (SV22) Programming
Manual (Advanced Synchronous Control)" for acceleration/deceleration time
change parameter.
Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller (SV13/SV22)
Programming Manual (REAL MODE)" for acceleration/deceleration time change
function.
