High-speed Input Request Signal
Set the high-speed input request signal used for mark detection. Use the high-speed input request signal settings to specify
the input signal detection direction and compensation time. Mark detection accuracy is determined by the high-speed input
request signal accuracy setting.
Setting range
1 to 64
When mixed operation cycle function is enabled, set the setting No. of the high-speed input request signal
where the high-speed input request signal control cycle setting matches the control cycle of the axes set in the
mark detection data. If the control cycles do not match, a moderate error (error code: 30D5H) occurs. Refer to
mixed operation cycle function for details. (Page 160 Mixed Operation Cycle Function)
Mark detection process compensation time
The mark detection process delay time can be compensated. Set this time if wishing to compensate delays and so on inherent
to mark detection process separately from the high-speed input request signal compensation time. (If compensating the delay,
set a positive value.) However, when "Invalid" is selected for estimation calculation, the mark detection process compensation
time cannot be set. (The time will be 0 [s].)
In indirect setting, the timing is compensated as "-5000000" when the compensation time is set to less than -5000000, and it
is compensated as "5000000" when it is set to more than 500000.
■Direct setting
Setting range
-5000000 to 5000000[s]
■Indirect setting
Word devices are used for the mark detection process compensation time. Set an even number for the device number. Refer
to device list for the range of word devices that can be set. (Page 75 Device List)
When using the "real current value" in mark detection data, set the mark detection signal compensation time referring to the
following chart.
