16 POSITIONING INSTRUCTION
16.1 Dedicated Instruction (Positioning Function)
843
16
DSZR [For the FX5 operand specification]
This instruction executes mechanical zero return.
Setting data
■
Descriptions, ranges, and data types
*1 Specify K1 to K4 (axis 1 to 4) for the CPU module, and K5 to K12 (axis 5 to 12) for the high-speed pulse input/output module.
■
Applicable devices
*1 T, ST, C cannot be used.
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).
