Millimeter machine 1 mm/min 10 to 60000 1 to 6000
Inch machine 0.1 inch/min 10 to 60000 1 to 6000
Rotation axis 1 deg/min 10 to 60000 1 to 6000
If zero specified for all axes, the machine does not decelerate at corners.
When the function for determining the velocity considering the velocity
difference at corners is used, the system calculates the feedrate whereby
a change in the velocity element of each axisdoes not exceed this
parameter value at the interface between blocks. Then the machine
decelerates using acceleration/deceleration before interpolation.
