Operand specification
■When FX5 operand is specified
1. For (s), specify the command speed. Set to a value -200 kpps to +200 kpps in pulse. For the FX5S CPU module, set to a
value -100 kpps to +100 kpps.
• PLSV: -32768 to +32767 (User system unit)
• DPLSV: -2147483648 to +2147483647 (User system unit)
2. For (d1), specify an axis number for which pulses are output.
Specify an axis number whose positioning parameters are set in the high speed I/O parameters. Operation cannot be
performed if any other axis number is specified.
[FX5S CPU module]
• K1 to K4: Axis 1 to Axis 4
[FX5UJ CPU module]
• K1 to K3: Axis 1 to Axis 3 (CPU module)
• K5, K6: Axis 5, Axis 6 (High-speed pulse input/output module first module)
• K7, K8: Axis 7, Axis 8 (High-speed pulse input/output module second module)
• K9, K10: Axis 9, Axis 10 (High-speed pulse input/output module third module)
• K11, K12: Axis 11, Axis 12 (High-speed pulse input/output module fourth module)
[FX5U/FX5UC CPU module]
• K1 to K4: Axis 1 to Axis 4 (CPU module)
• K5, K6: Axis 5, Axis 6 (High-speed pulse input/output module first module)
• K7, K8: Axis 7, Axis 8 (High-speed pulse input/output module second module)
• K9, K10: Axis 9, Axis 10 (High-speed pulse input/output module third module)
• K11, K12: Axis 11, Axis 12 (High-speed pulse input/output module fourth module)
3. For (d2), specify the bit devices of the instruction execution complete flag and abnormal end flag. (Page 417
Complete flag)
• (d2): Instruction execution complete flag
• (d2)+1: Instruction execution abnormal end flag
■When the FX3 compatible operand is specified (Supported only for CPU module)
1. For (s), specify the command speed. Set to a value -200 kpps to +200 kpps in pulse. For the FX5S CPU module, set to a
value -100 kpps to +100 kpps.
• PLSV: -32768 to +32767 (User system unit)
• DPLSV: -2147483648 to +2147483647 (User system unit)
2. For (d1), specify the pulse output number.
Specify an output device (Y) number set in the high speed I/O parameters. (Page 382 Pulse Output Mode) Operation
cannot be performed if any other axis number is specified.
• FX5S/FX5U/FX5UC CPU module: Y0 to Y3 (equivalent to axes 1 to 4)
• FX5UJ CPU module: Y0 to Y2 (equivalent to axes 1 to 3)
3. For (d2), specify the rotation direction signal output device number. (Page 384 Rotation Direction Setting)
When an output device (Y) is used, only the device that is specified with the positioning parameter or a general-purpose
output can be specified. However, if an output device (Y) to which PWM, PULSE/SIGN axis of another axis, or CW/CCW axis
is assigned is specified, an error occurs without any operation.
For the PWM function, refer to the following.
