12 CONTROL SUB FUNCTIONS
1 The near pass function is validated only when the machine of the standard specification carries out the position control
with the continuous path control mode.
It cannot be invalidated with parameters.
2 To carry out "torque limit", the "D/A conversion module" and a "drive unit capable of the torque limit command with an
analog voltage" must be prepared.

3 To execute the "absolute position restoration function", the following are required: "16-point input module"; "16-point
output module"; and "drive unit capable of configuring an absolute position detection system, which is a Mitsubishi
Electric General-Purpose AC Servo having an absolute position detection function (absolute position data transference
protocol) equivalent to that of MR-J3- A".
This function restores the absolute position of designated axis. By this
3 function, the OPR after power ON from OFF is not required once the OPR is
executed when the system operation is started.
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 ( Da.6 Positioning address/movement amount) having
the designated positioning data No.
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" to 1.
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.
(acceleration/deceleration time and curve).
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.
