"The 16-point input module", "16-point output module", and "the drive unit capable of configuring an
3
absolute position detection system" are required to execute the "absolute position restoration function".
This function restores the absolute position of the designated axis.

This function temporarily stops the operation to confirm the positioning
operation during debugging, etc.
The operation can be stopped at each "automatic deceleration" or
"positioning data".
This function stops the positioning being executed (decelerates to a stop)
when the skip signal is input, and carries out the next positioning.
This function issues a sub work (clamp or drill stop, tool change, etc.)
according to the code No. (0 to 65535) set for each positioning data.
This function stores the address positioned with manual control into the
positioning address (
the designated positioning data No.
This function changes the target position during the execution of positioning.
At the same time, this also can change the speed.
At each automatic deceleration, this function calculates the remaining
distance for the QD75 to reach the positioning stop position, and when the
value is less than the set value, sets the "command in-position flag".
When using another sub work before ending the control, use this function as
a trigger for the sub work.
This function adjusts the control acceleration/deceleration.
This function shortens the virtual start time.
Function that turns ON the flag when the constant speed status or
acceleration status switches to the deceleration status during position
control, whose operation pattern is "Positioning complete", to make the stop
timing known.
Function that selects a deceleration curve when a stop cause occurs during
deceleration stop processing to speed 0.
