proximity dog ON
[RJ010 mode]
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 HP shift operation of HPR control: Stores the value of HP 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.

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 HPR starts.

After machine HPR starts, the movement amount from the proximity dog ON to
the machine HPR completion is stored.
(Movement amount: Movement amount to machine HPR completion using
proximity dog ON as "0".)

Storage details
: Stores "0".
: The actual target speed, considering
the override and speed limit value,
etc., is stored. "0" is stored when
positioning is completed.
: The composite speed or reference
axis speed is stored in the reference
axis address, and "0" is stored in the
interpolation axis address.
: The target speeds of each axis are
stored in the monitor of the reference
axis and interpolation axis.
: The actual target speed, considering
the JOG speed limit value for the
JOG speed, is stored.
