(a) Function
• This instruction is for PWM output.
• While the input condition is On state, XGB postioning outputs pulse train in designated cycle time
in n1 and designated Off duty rate in n2 at designated axis in ax
• During PWM output, current address don’t change. Constant speed bit(X axis: K0420D, Y axis:
K0430S) and Operation bit(X axis: K04200 Y axis: K4300) set On.
(b) Error
• If the value designated as ax (instruction axis) is other than 0 and 1, the error flag (F110) is set
and the instruction is not executed.
Remark
• If PWM instruction is executed, other instruction do not operate. And upper/lower limit does not
work
• If PWM instruction is executed, STP, EMG instruction doesn’t operate. To stop output, Off the
Start-up contact
• If output cycle is changed, when operating APM_PWM, it cannot be applied.
• PWM applicable version
