Sub function Details
Reference
section
Absolute position system
This function restores the absolute position of designated axis.
If the OPR is executed at the start of system, after that, it is
unnecessary to carry out the OPR when the power is turned ON.
13.6
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".
13.7.1
Skip function
This function stops (decelerates to a stop) the positioning being
executed when the skip signal is input, and carries out the next
positioning.
13.7.2
M code output function
This function issues a command for a sub work (clamp or drill
stop, tool change, etc.) corresponding to the M code No.
(0 to 65535) that can be set for each positioning data.
13.7.3
Teaching function
This function stores the address positioned with manual control
into the "
Da.6
Positioning address/movement amount
" having the
designated positioning data No. (
Cd.39
).
13.7.4
Command in-position
function
At each automatic deceleration, this function calculates the
remaining distance for the QD77MS to reach the positioning stop
position. When the value is less than the set value, the
"command in-position flag" is set to "1".
When using another auxiliary work before ending the control,
use this function as a trigger for the sub work.
13.7.5
Acceleration/deceleration
processing function
This function adjusts the acceleration/deceleration. 13.7.6
Continuous operation
interrupt function
This function interrupts continuous operation. When this request
is accepted, the operation stops when the execution of the
current positioning data is completed.
6.5.4
Pre-reading start function This function shortens the virtual start time. 13.7.7
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.
13.7.8
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.
13.7.9
Follow up function
This function monitors the motor rotation amount with the servo
turned OFF, and reflects it on the current feed value.
13.8.2
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".
13.7.10
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.
13.7.11
1: The near pass function is featured as standard and is valid only for position control. It cannot be set to be invalid with parameters.
