FX Series Programmable Controlers
PWM (FNC 58)
Points to note:
a) Because this is a 16 bit instruction, the available time ranges for S
b) A calculation of the duty cycle is easily made by dividing S
c) The PWM instruction may only be used once in a users program.
d) Because of the nature of the high speed output, transistor output units should be used with

between two pulses, i.e. a second pulse would start before the first had finished. If this is
programmed an error will occur.
This instruction is used where the length of the pulse is the primary concern.
this instruction. Relay outputs will suffer from a greatly reduced life and will cause false
outputs to occur due to the mechanical ‘bounce’ of the contacts. To ensure a ‘clean’ output
signal when using transistor units, the load current should be 200mA or higher. It may be
found that ‘pull up’ resistors will be required.

Operation:
A continuous pulse train is output through device D
when this instruction is driven. The characteristics
of the pulse are defined as:
