The trigger parameters are listed in the table below. .

RP[N]	Definition
RP[0]: Recorder time quanta	0: The recorder time quantum is the speed controller
	sampling time ( 4 TS usec)
	1: The recorder time quantum is the torque controller
	sampling time TS usec.
RP[1]: Trigger variable	Defined similarly to RC, but only 1 bit may be non-
	zero.
	The trigger variable does not need to be one of the
	recorded variables.
	For example, RV[1]=17, RP[1]=1 defines that the
	trigger will be made on signal #17 (the stator's field
	angle).
	⋅
RP[2]: Pre trigger storage in	0 to 100 (percent)
percents.
RP[3]: Trigger type	0 for immediate
	1 for a BG
	2 for positive slope
	3 for negative slope
	4 for window
	5 reserved for future digital input trigger option.
RP[4]: Level 1	Level for positive slope trigger, or high side for
	window trigger
RP[5]: Level 2	Level for negative slope trigger, or low side for window
	trigger

The trigger levels RP[4] and RP[5] can be entered either as integer or floating point
