When there is a standard axis, which passes a constant position at the cycle operation,
the deceleration can be started at the specified timing. By setting the parameter of the
standard axis (No.7524) and the absolute coordinate position (No.7525), the deceleration
is started after the retract signal is input and the standard axis passes the specified
absolute coordinate position.
For example in the figure below, at X axis is operating the back and forth and C axis is
operating equal velocity rotates, if the deceleration stop at the position where X axis is the
farthest from C axis, C axis is assumed to be a standard axis and the absolute coordinate
position are assumed to be 0deg.
(C axis is rounded to 360deg.)

  • Page 7It is possible to decelerate and stop the remote buffer operation at finishing the retract value 2 movement after inputting the retract signal. 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

  • Page 93. 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 sig
