MINRPM	RPM	MINUTES PER REPEAT or REPEATS PER MINUTE—
	MIN [factory setting]	Use this parameter to choose whether you want to specify
		the integral term (reset) in the PIDA algorithm in terms of
		length (minutes per repeat) or frequency (repeats per
		minute). Your choice here affects which tuning prompt, “I
		MIN” or “I RPM”, is displayed.
		The relationship between the two ways of thinking about
		reset is demonstrated by this example:
		20 repeats per minute = 0.05 minutes per repeat.
		This parameter is displayed only if the “CTRALG” (control
		algorithm) is set to “PIDA”.
			ATTENTION	If the setting of MINRPM is changed,
		you must change the value of the associated tuning
		parameter (“I MIN” or “I RPM”) if you want to maintain the
		same control action. For example, suppose MINRPM = I
		RPM and the value of tuning parameter “I RPM” = 2. If
		you change MINRPM to I MIN, the value of “I MIN” will
		now be 2 (the value formerly assigned to “I RPM”). If you
		want the same control action you had before, you must
		change the value of “I MIN” to 0.5.
