PLSV2: Variable-speed pulse output with acceleration/deceleration
Overview
Pulses are output through the specied output port at the specied frequency and direction. Acceleration/
deceleration is supported. When the ow is inactive, the pulse output is decelerated to stop.

Functions and actions
This instruction is used to output pulses at the specied frequency and running direction through the
specied port. Acceleration/deceleration is supported. When the drive ow is inactive, the pulse output is
decelerated to stop. This instruction is applicable only to the PLC of the transistor output type.
S1 indicates the specied pulse output frequency. For a 16-bit instruction, the range is 50 to 32,767 Hz and
-50 to -32,768 Hz. For a 32-bit instruction, the range is 50 to 200,000 Hz and -1 to -200,000 Hz. The "-"
indicates an instruction signal running in the reverse direction.
D1 indicates the pulse output port which can be Y0, Y1, Y2, Y3, or Y4.
D2 indicates the running direction of the output port or the bit variable. If output is ON, it means running in
the forward direction; otherwise, it means running in the reverse direction.
When the instruction ow is OFF, the pulse output is decelerated to stop, and the execution complete ag
M8029 remains unchanged. After the instruction driving point switches to OFF and the ag is ON during
pulse output, the ag is no longer driven by the instruction. When the ow switches from OFF to ON, the
pulse output resumes.
The following gure shows a pulse output diagram.
After the instruction is enabled, the pulse output frequency is accelerated from the base frequency to
the set frequency. When the pulse output frequency is changed, the output frequency is automatically
accelerated or decelerated to the changed output frequency. When the ow is inactive, the pulse output is
