Processing details
This instruction executes mechanical zero return. The near-point dog signal and zero-phase signal function follow the device
set with parameters. With the forward limit or reverse limit, zero return with the dog search function can be executed.
• For (s1), specify the zero return speed in the user units. (The speed must be 200 Kpps or lower in frequency.)
• For (s2), specify the creep speed in the user units. Set the creep speed equal to or slower than the zero return speed set in
(s1). (The speed must be 200 Kpps or lower in frequency.)
• For (d1), specify the axis number for which zero return is performed.
• For (d2), specify the bit device of the zero return complete flag or abnormal end flag.
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).
