16 POSITIONING INSTRUCTION
16.1 Dedicated Instruction (Positioning Function)
861
16
16-bit data variable speed pulse
PLSV [For the FX3 compatible operand specification]
This instruction outputs variable speed pulses with an assigned rotation direction output. The high-speed pulse input/output
module is not supported.

Applicable devices
*1 Only Y can be used.
*2 When the output mode is CW/CCW, specify the CCW axis. When the output mode is PULSE/SIGN and using Y, only the SIGN output or
general-purpose output of the self-axis can be specified.
*3 T, ST, C cannot be used.
Processing details
This instruction outputs variable speed pulses with an assigned rotation direction output.
• For (s), specify the command speed to be output. (The speed must be 200 Kpps or lower in frequency.)
• For (d1), specify the device from which pulses are output. Only the output devices (Y) having positioning parameters can
be specified.
• For (d2), specify the device from which the rotation direction signal is output. Only the device specified with the parameter
or general-purpose outputs can be specified. When the output devices (Y) is executed by another function (PWM,
positioning PULSE axis, or CW/CCW axis etc.), the device does not function and causes an error.
For details on the function, precautions, and error code, refer to
MELSEC iQ-F FX5 User's Manual (Positioning Control -
CPU module built-in, High-speed pulse input/output module).
