• Output
The following functions occupy outputs of the high-speed input/output function. The channels and the axis numbers are in
module internal order. The following functions cannot be combined with other high-speed input/output functions.

*1 : Head output number for each high-speed pulse input/output module
Precautions
Do not specify an output device (Y) used by the high-speed input/output function as the output destination of the high-speed
comparison table.
Restrictions on simultaneous execution of the high-speed comparison table and high-
speed comparison instructions
There is a limit in the number of simultaneous executions of the high-speed comparison table and high-speed comparison
instructions (DHSCS, DHSCR, DHSZ instruction). Shown below are the conditions included in the number of the
simultaneous executions. For high-speed comparison table, refer to MELSEC iQ-F FX5 User's Manual (Application). For
high-speed comparison instructions and HIOEN/DHIOEN instruction, refer to MELSEC iQ-F FX5 Programming Manual
(Instructions, Standard Functions/Function Blocks).

executions
High-speed counter • Drive high-speed comparison table (Drive HIOEN/DHIOEN
function instruction)
• Drive DHSCS, DHSCR, DHSZ instruction)
Positioning function • Interrupt input signal 1 (High-speed mode) setting is enabled
• For the high-speed comparison table, only the tables driven by the HIOEN/DHIOEN instruction are included
in the number of the simultaneous executions.
• When the positioning function setting is made, high-speed comparison table becomes occupied and is
included in the number of simultaneous executions.
Correction of backlash
The positioning function cannot correct mechanical backlash (clearance/
play). If it is necessary to correct the backlash, set the number of output
pulses taking into account the backlash that may be caused when
reversing the transfer direction beforehand.
