(2)Parameter No. 7515 setting >= remaining distribution count for the
current cycle
A number of pulses for retracting until the end of the current cycle are
superimposed on a usual operation. When retracting ends, the CNC
shifts to an automatic operation pause or retract cycle execution.

Automatic operation pause
The escape direction and speed for each axis are specified in parameter
No. 7514 (axis type parameter). An algebraic sign prefixed to the escape
speed represents the escape direction.
(Example) Parameter No. 7514: X = 10 (for metric machine)
Y=--20
Z=0
Retracting occurs at a speed of 10 mm/min in the positive direction
along the X--axis and 20 mm/min in the negative direction along the
Y--axis, but does not occur along the Z--axis (0 mm/min).
A reset interrupts retracting.
Cycle data can be registered with the cycle header. This data is used to
move the tool to a safer position or to decelerate high--speed motion about
a rotation axis and high--speed travel along other axes to a stop after
retracting ends.
Whether to enable retracting can be selected using a data type
specification variable in the cycle header. If retracting is disabled, the
retract signal is ignored. In a connection cycle, retracting begins with the
first enabled--retracting cycle to appear.
If no retract cycle is registered, the CNC shifts to an automatic operation
pause (see Section 5.1) after retracting. If a retract cycle is registered,
shifting to an automatic operation pause occurs after the retract cycle is
executed.
