Output cycle
● Setting rage: 1~20,000(ms)
DUTY
WORD
Off duty rate
● Setting range: 1 ~100(%)
(a) Fuction
• This instruction is for PWM output.
• While the input condition is On state, XGB postioning outputs pulse train in designated cycle time
in FREQ and designated Off duty rate in DUTY at designated axis in AXIS
• During PWM output, current address don’t change. Constant speed bit(X-axis: %K%6733, Y-
axis: %KX6893) and Operation bit(X- axis: %KX6720, Y- axis:%KX6880) set On.
