5 PARAMETERS FOR POSITIONING CONTROL
• An example for positioning control is shown below when the fixed parameter and parameter block are set
as follows.
• Fixed parameter
Setting axis Unit High-speed feed rate Speed control 10 multiplier setting for degree axis
Axis 1(X) degree 200.000[degree/min] Invalid
Axis 2(Y) degree 2000.00[degree/min] Valid

POINTS
After the "speed control 10 multiplier setting for degree axis" is set to "valid", when
the speed change is executed by Motion dedicated PLC instruction (S(P).CHGV) or
Motion program (CHGV instruction), the positioning control is executed by ten
times the command speed (set value).
