32 Bit Binary Pulse Width Modulation - Mitsubishi MELSEC iQ-F FX5 series Programming Manual

32 bit binary pulse width modulation

DPWM
This instruction outputs the pulse (in 32-bit data units) of the ON time (in 32-bit data units) specified by (s1) and the period
specified by (s2) to the output destination specified by (d).

(d)
*1 When a bit device is specified, specify one of Y0 to Y7.
Only Y can be used for a bit device.
If Y is specified, outputs are enabled when there is an unused channel number in the parameter setting and the specified Y number is
not used.
The nibble of a bit device cannot be specified.
*2 When a word device or constant is specified, specify one of the CH numbers.
Processing details
• This instruction outputs the pulse of the ON time specified by (s1) and the period specified by (s2) to the output destination
specified by (d).

(s1)
(s2)
• Time with a unit selected on the parameter setting screen (s or ms) can be specified by (s1) and (s2).
• The pulse output destination channel number selected on the parameter setting screen can be specified by (d).
• This instruction stores the number of pulses, pulse width, and period output from each channel to an SD device. The pulse
width and period are stored in the units set by the parameters. When 0 is specified in the pulse output, pulses are output
without any limitation.
