Enter a value in milligees for the desired acceleration rate. A milligee (milliG) is 1/1000 of a G, which
is the acceleration due to gravity. One milligee is approximately 0.384 inches per second
2
. A good
starting point for most systems is 10 mgee‟s.
Fast Stop Deceleration Rate
Activated by the Fast Stop or Torch Collision Input, the Fast Stop Deceleration Rate Parameter
specifies in milligees how quickly the system will stop when the Fast Stop Input is active. Generally,
this value is much higher then the Acceleration rate.

Maximum Machine Speed
Enter the maximum value at which the system is capable of contouring. This parameter will be used
to range limit all subsequent speed entries. In addition, it is used to scale the speedometer widget in
the Watch window during runtime operation.
The maximum speed at which the control can contour can be calculated with the following equation.
Maximum Contouring Rate (IPM) =
60 seconds

100,000 edges
minute User edges second
For example: the control could command a cutting machine with 4000 edges per inch resolution at
1,500 IPM.
Limited Machine Speed
The Limited Speed feature allows for a user-defined maximum machine speed when the Limited
Speed Input is active. This is commonly used to set a reduced machine speed for the purpose of
increased safety when testing or maintenance of the machine is being performed.
High Jog Speed
Enter a value for the desired high manual motion speed.
Medium Jog Speed
Enter a value for the desired medium manual motion speed.
Low Jog Speed
Enter a value for the desired low manual motion speed.
Minimum Corner Speed
This is the minimum speed to use when negotiating corners. The control has sophisticated
centripetal velocity and acceleration contouring algorithms, which should provide optimal cut quality
for most cut operations. In some situations it may be desirable to enter a minimum corner speed to
prevent over-burning at corners. In normal operations, this parameter should be set to zero.
