5 DATA USED FOR POSITIONING CONTROL
Storage item Storage details
Md.33
Target speed
•
During operation with positioning data : The actual target speed, considering
the override and speed limit value,
etc., is stored. "0" is stored when
positioning is completed.
•
During interpolation : The composite speed or reference
axis speed is stored in the reference
axis address, and "0" is stored in the
interpolation axis address.
•
During JOG operation : The actual target speed, considering
the JOG speed limit value for the
JOG speed, is stored.
•
During manual pulse generator operation : "0" is stored.
POINT
The target speed is when an override is made to the command speed.
When the speed limit value is overridden, the target speed is restricted to the
speed limit value. The target speed changes every time data is switched, but
does not change in an acceleration/deceleration state inside each piece of data
(changes with the speed change because the target speed changes.)
Md.34
Movement amount after
near-point dog ON
•
"0" is stored when machine OPR starts.
•
After machine OPR starts, the movement amount from the near-point dog ON to
the machine OPR completion is stored.
(Movement amount: Movement amount to machine OPR completion using near-
point dog ON as "0".)
•
"0" is always stored when not using the near-point dog.
