Acceleration Rate: Determines both the acceleration and deceleration rate for all motion.
All mechanical systems have different acceleration and deceleration rates to move the cutting device
smoothly. The higher the acceleration rate, the quicker the machine will get up to speed. The lower the
acceleration rate, the smoother the machine will position the cutting device.
Enter a value in milliGs for the desired acceleration rate. One milliG is approximately 0.384 inches per
second
2 . A recommended, initial value for this field is 10 milliGs.
Peak S Curve Acceleration displays the maximum acceleration used during the beginning of a cut and represents a
rate of acceleration that is 50% greater than the average rate of acceleration. This parameter appears when
S Curve Acceleration (at the lower left in the Speeds Screen) is set to Yes.
Fast Deceleration Rate: This parameter is activated by the Fast Stop or Torch Collision inputs and specifies in milliGs
how quickly the system will stop when the Fast Stop Input is active. Generally, this value is much higher than
the acceleration rate.
One milliG is approximately 0.384 inches per second 2 .
Maximum Machine Speed: Enter the maximum value at which the system is capable of contouring. This parameter
limits the range of all subsequent speed entries. In addition, it scales the speedometer in the Watch Window
during runtime operation.
The maximum speed at which the CNC can contour can be calculated with the following equation.
Maximum Contouring Rate (IPM) =
For example: the CNC could command a cutting machine with 4000 edges per inch resolution at 1,500
IPM.
Limited Machine Speed: Defines maximum machine speed when the Limited Speed Input is active. This is commonly
used to set a reduced machine speed for increased safety during machine testing or maintenance.
High Jog Speed: Defines the high speed for manual motion.
Medium Jog Speed: Defines the medium speed for manual motion.
Low Jog Speed: Defines the low speed for manual motion.
Minimum Corner Speed: Defines the minimum speed to use when negotiating corners. The CNC has centripetal
velocity and acceleration contouring algorithms which provide optimal cut quality for most cut operations. In
some situations, a minimum corner speed prevents over-burning at corners. In normal operations, this
parameter should be set to zero.
Fast Home Speed: Defines the speed that the CNC uses during the first phase of the homing sequence. During the
first phase, the cutting device moves toward the home limit switches at the fast rate.
Slow Home Speed: Defines the speed that the CNC uses during the second phase of the homing sequence. During
the second phase, the cutting device moves off the home limit switch and proceeds to the marker pulse.
When the CNC detects the marker pulse, it decelerates to a stop and performs a small move in the opposite
direction to the marker pulse.
