*1 When the output is Q0 or Q1 and the calculated OFF time is shorter than 15 μs, the pulse duty cycle is adjusted so that the OFF time becomes
15 μs, and then the pulse is output.
*2 For details on the output delay time of each output, see Chapter 2 "Product Specifications" in the "FC6A Series MICROSmart User's Manual".
3. S1 (source 1): Control register
S1 specifies the first data register of the data registers to use with PWM1, PWM2, PWM3, or PWM4 instructions.
Starting from the specified data register, 8 consecutive data registers are used.
Specify the first data register so that the device range is not exceeded.

*1 The upper and lower data registers change according to the 32-bit data storage method specified.
For details, see "32-bit Data Storage" on page 3-9.
4. S2 (source 2): Initialization Input
S2 specifies the initialization input. When the initialization input S2 is turned on, the initial values configured in the WindLDR
PWM (Pulse Width Modulation) dialog box, on the Settings tab, are stored in the control registers. An external input or an
internal relay can be specified.
When the initialization input is on, the initial values are written to the data registers with each scan. To only initialize the values
one time, use the initialization input in combination with the SOTU (single output up) instruction or the SOTD (single output
down) instruction.
5. D1 (destination 1): Operation Status
D1 specifies the first internal relay of the internal relays to use with PWM instructions.
Starting from the specified internal relay, 3 sequential internal relays are used.
Specify the first internal relay so that the device range is not exceeded.

This relay turns on during pulse output.
This relay turns off when pulse output stops.
This relay turns off when the specified number of pulses
are output and output ends.
This relay turns on when pulse output is complete.
This relay turns off when pulse output stops.
When pulse counting is enabled, this relay turns on when
a pulse is output that exceeds the configured preset value.
