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 axis number from which pulses are output.
• For (d2), specify the bit device of the normal complete flag or abnormal end flag for the DDVIT instruction.
For details on the function and error code, refer to MELSEC iQ-F FX5 User's Manual (Positioning Control - CPU module
built-in, High-speed pulse input/output module).
Precautions
Two devices are occupied from the device specified in (d2). Make sure that these devices are not used in other controls.
For other precautions, refer to MELSEC iQ-F FX5 User's Manual (Positioning Control - CPU module built-in, High-speed
pulse input/output module).
