Storage item
[Md.32] Target value

near-point dog ON
This area stores the target value ([Da.6] Positioning address/movement amount)
for a positioning operation.
At the beginning of positioning control and current value changing:
Stores the value of "[Da.6] Positioning address/movement amount".
At the OP shift operation of OPR control : Stores the value of OP shift amount.
At other times
Refresh cycle: Immediate
During operation with positioning data
During interpolation of position control
During interpolation of speed control
During JOG operation
During manual pulse generator operation : "0" is stored.
Refresh cycle: Immediate
[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.)
"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".)
Refresh cycle: Immediate
