1. Instruction format
2. Set data
3. Applicable devices
S1: Specify transistor output Y000, Y001, or Y002 on the main unit or Y000, Y001, Y002, or Y003 on a special high-
speed output adapter
*1
.
S2: This function is supported only in FX3U/FX3UC PLCs.
*1. Y002 is not available in FX3G PLC (14-point and 24-point type) and FX3GC PLC.
*2. High-speed output special adapters can be connected only to FX3U PLC.
Explanation of function and operation
1. 16-bit operation (PWM)
Pulses whose ON pulse width is ms are output in periods of ms.
