12 CONTROL SUB FUNCTIONS
Sub function
Details
Absolute position system function
This function holds the current value.
This function sets the absolute position coordinate in relation to the OP in the
machine movement range, and prevent the OP from being lost even if the
power supply is turned OFF to ON.

Step function
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".
operation during debugging, etc.
The operation can be stopped at each "automatic deceleration" or
"positioning data".
Skip function
This function stops the positioning being executed (decelerates to a stop)
when the skip signal is input, and carries out the next positioning.
when the skip signal is input, and carries out the next positioning.
M code output function
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.
according to the code No. (0 to 65535) set for each positioning data.
Teaching function
This function stores the address positioned with manual control into the
positioning address (
positioning address (
Da.6
Positioning address/movement amount) having
the designated positioning data No.
Target position change
function
function
This function changes the target position during the execution of positioning.
At the same time, this also can change the speed.
At the same time, this also can change the speed.
Command in-position
function
function
At each automatic deceleration, this function calculates the remaining
distance for the QD75MH 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.

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.
Acceleration/deceleration
process function
process function
This function adjusts the control acceleration/deceleration.
Pre-reading start function This function shortens the virtual start time.
Deceleration start flag
function
function
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.
acceleration status switches to the deceleration status during position
control, whose operation pattern is "Positioning complete", to make the
stop timing known.
Stop command processing
for deceleration stop
function
for deceleration stop
function
Function that selects a deceleration curve when a stop cause occurs
during deceleration stop processing to speed 0.
during deceleration stop processing to speed 0.
Speed control 10 x
multiplier setting for degree
axis function
multiplier setting for degree
axis function
This function is executed the positioning control by the 10 x speed of the
command speed and the speed limit value when the setting unit is "degree".
command speed and the speed limit value when the setting unit is "degree".
Other functions

incompletion of OPR
function
incompletion of OPR
function
This function is provided to select whether positioning control is operated or
not, when OPR request flag is ON.
not, when OPR request flag is ON.
