*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 executes interrupt 1-speed constant quantity feed.
• For (s1), specify the transfer distance that is output after an interrupt, in user units. (The distance must be within the range
of -2147483647 to +2147483647 number of pulses.)
• For (s2), specify the speed in user units. (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 a 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 Built-in positioning manual.
