37-5
Function
Use this parameter to determine when the control recognizes a high-speed
trigger signal from some external device to execute one of the skip or
probing functions. The control recognizes a high-speed trigger signal
when the signal is turned on or off.
Rising edge -- When this parameter is set at “Rising edge,” the control
recognizes a high-speed input signal when the probe turns on (rising edge
of the signal).
Falling edge -- When this parameter is set at “Falling edge,” the control
recognizes a high speed input signal when the probe turns off (falling edge
of the signal).

Notes
This is a global parameter; the value set here applies to all axes
and processes.
This parameter is not available on the 9/230 control.
Function
Use this parameter to force the control to execute only dwells (G04) in
units of seconds.
Time & Spn Revs -- When this parameter is selected as “Time & Spn
Revs,” a dwell may be programmed in second or in spindle revolutions.
Dwells that are programmed in G94 mode are in units of seconds, and
dwells that are programmed in G95 mode are in units of spindle
revolutions.
