3. Notes
1) The value of the deceleration movement is made based on the feedrate and the time
constant at the beginning of the deceleration. Moreover, this value of the movement is
not included in the value of retract.
2) Even if the high-speed remote buffer is operated, the input of the retract signal is read in
every 8msec only.
3) The retract movement moves by the superimposed to the feedrate. In that case,
maximum cutting feedrate is not clamped. Moreover, the acceleration/deceleration of
the retract operation is superimposed to the feedrate, and please set the feedrate and
the time constant by considering these points.
4) Even if the high-speed remote buffer operation and the retract operation are finished
without the standard axis passing the setting absolute position after inputting the retract
signal, it enters the state of reset.

Specification The retract operation is done to each axis when the retract signal is input while operating the high-speed remote buffer, and the high-speed remote buffer operating does the deceleration stop. It enters the state of reset after retraction. The acceleration/deceleration type of the r

When the parameter No.7502#6 is set to 1 and the standard axis for retract is set to the 3 parameter No.7524, the remote buffer operation is decelerated and
