Feedrate Parameters
Chapter 9
9-8
Function
Enter the feedrate to which the axis is to decelerate when an external
deceleration request is sent to PAL during a positioning move (G00 active).
This feature requires coordination with the PAL program and is usually set
up to operate as follows:
An axis travel switch is placed at a point where you want to slow down
axis travel. Usually this is some place near the hardware overtravel. When
the switch is tripped, the PAL flag “External Deceleration Request” is set
TRUE, and the control decelerates each axis to the feedrate entered for
this parameter.
As long as the PAL flag remains TRUE, the motion of each axis in any
direction is restricted to the feedrate entered here. Refer to your PAL
reference manual for more information.
Jogging moves are not affected by this parameter.
