Chapter 13 Control Sub Functions
Sub function Details
Absolute position system function
This function restores the absolute position of designated axis.
By this function, the OPR after power ON from OFF is not required once the
OPR is executed when the system operation is started.
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".
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.
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.
Teaching function
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.
Command in-position
function
At each automatic deceleration, this function calculates the remaining
distance for the QD77MS 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.
Acceleration/deceleration
processing function
This function adjusts the control acceleration/deceleration.
Pre-reading start function This function shortens the virtual start time.
Deceleration start flag
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.
Stop command processing
for deceleration stop
function
Function that selects a deceleration curve when a stop cause occurs
during deceleration stop processing to speed 0.
Follow up function
This function monitors the motor rotation amount with the servo turned
OFF, and reflects it on the current feed value.
Speed control 10 x
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".
Other functions
Operation setting for
incompletion of OPR
function
This function is provided to select whether positioning control is operated or
not, when OPR request flag is ON.
