Bit Binary Pulse Width Modulation - Mitsubishi Electric MELSEC iQ-F FX5 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).

*1 Only Y can be used for a bit device.
When a bit device is specified, specify one of Y0 to Y7. The high-speed pulse input/output module bit device (Y) cannot be specified.
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.
Specify K1 to K4 (axis 1 to 4) for the CPU module, and K5 to K12 (axis 5 to 12) for the high-speed pulse input/output module.
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).
