15843 Retraction limit position
Data type : DWord
Unit : 0.001mm
Range : 0～99999999
Specify a machine coordinate of retraction limit position when Z-axis is
retracted. When Z-axis reaches this position, Z-axis starts to decelerate and
stops. If set value is zero, limit function by this parameter is not available.
This parameter must be set below + OT position of Z-axis.
15844 Minimum distance that automatic gap control axis retraction and
approaching function is executed.
Data type : DWord
Unit : 0.001mm
Range : 0～99999999
Specify the minimum distance that this function can be executed.
When positioning distance of the basis axis is shorter than this value,
automatic gap control axis retraction and approaching function is not executed.
15845 Approach velocity
Data type : Word axis
Unit : mm/min
Range : 0～65535
Specify the approach velocity of high speed approach function.
If this value is zero, high-speed approach function does not work.
If too much value is set in this parameter, the gap control axis cannot be
decelerated enough. As a result, the gap control axis may touch the workpiece.
Please be careful in case of changing this parameter.
The value set in this parameter is used as retraction and approaching velocity
when automatic gap control axis retraction and approaching function of is
executed.
15857 Maximum approach feedrate
Data type : Word axis
Unit : mm/min
Range : 0～65535
Specify the maximum approach federate in gap control.
15858 Maximum retraction federate
Data type : Word axis
Unit : mm/min
Range : 0～65535
Specify the maximum retraction feedrate in gap control.
15861 Ratio of the rest positioning distance to the distance of the basis
axis until completing Z-axis retraction
Data type : Word
Unit : %
Range : 0～20000
Specify the ratio of the rest positioning distance of the basis axis to the
distance of basis axis until completing Z-axis retraction.
If a set value of parameter No.15861 is zero, it is regarded as 70.
