Outline of operation
● The PWM output is performed from a specified output. The output is performed when the
execution condition is ON.
● The output frequency and cycle are determined by a specified control code. The duty ratio is
specified in the operand [S1+1].
■
Precautions during programming
● This instruction cannot be executed when a control active flag corresponding to each
channel is ON.
● The duty may be different from the set ratio according to the load voltage and load current
especially in the vicinity of minimum and maximum values. The duty can be changed for
each scan. However, the control code cannot be changed during the execution of an
instruction.
● When rewriting during RUN is performed during the operation, the PWM output stops while a
program is being rewritten.
