Baldor MN850, Baldor manual RatedCurrent x

Title	P#		Parameter	Description
Parameters	P20	Reference PF (Power Factor)		The calculated power factor to optimize the control loop.
	P21	Present PF (Power Factor)		The present power factor of the motor (load).
	P22	Delay Angle (SCR OFF time)		The period (in degrees) that the thyristors are in the OFF state.
	P23	Maximum Optimizing Delay		Sets the maximum delay angle (max degrees that the thyristors are
				OFF) used during the optimizing mode.
	P24	Rated Current (High Byte –Hundreds)		The current rating of the soft–start set by manufacturer.
	P25	Rated Current (Low Byte – Units)		The current rating of the soft–start set by manufacturer.
	P26	Running Current Amps		The load current. (Always shown as phase current).
		(RatedCurrent) x (7.96875)
		32
	P27	Peak Start Current (measured at last start)		The maximum current used during the last start–up.
Advanced Current	P28	Low Current Level (undercurrent trip)		Sets the under current trip level. (The low current level flag is
		(scaling = 0.03125)		updated even if the low current trip is disabled).
	P29	Low Current Time (delay before trip)		The number of cycles allowed for a low current level condition (P28)
				to exist before tripping. For 60 Hz, 40 cycles = 667ms.
				For 50 Hz, 40 cycles = 800ms.
	P30	Current Limit Level (scaling = 0.03125)		Sets the level that the start ramp is held. (The start ramp is only held
			(RatedCurrent) x (7.96875)	if the P30 value is reached. The current decreases as motor speed
				increases allowing the ramp to continue).
			32
	P31	Current Limit Time (delay before trip)		The time allowed for start current to equal P30 value before tripping.
				Note that for 60 Hz, 40 cycles = 667ms.
				For 50 Hz, 40 cycles = 800ms.
	P32	Shearpin Level (overcurrent trip)		Sets the over current trip level. Shearpin operation begins after
				start–up is complete.
	P33	Shearpin Time (delay before trip)		The number of cycles allowed for an overcurrent condition before
				tripping (only when shearpin flag P51, Bit3=1). For 60 Hz, 60 cycles
				= 1second. For 50 Hz, 50 cycles = 1second.
	P34	Overload Level (SCR protection)		Sets the overload current level as a portion of FLA. (P34 is always
				active but P30 is only active during motor starting.)
	P35	Overload Delay (delay before trip)		The time allowed for an overload condition before tripping. For 60
				Hz, 60 cycles = 1second. For 50 Hz, 50 cycles = 1second.
Parameters	P36	% Overload (status only)		The integration of the Current–Time product represented as a % of a
				value that was preset by the manufacturer.
	P37	Chassis Temp		The heatsink temperature. When the temperature exceeds a
				threshold value, P37 value will change from <20 to >200.
	P38	Pot1		The value of RV1 on the control card. 255=fully CW setting for
				5VDC input. (Not applicable for keypad operation).
	P39	Pot2		The value of RV2 on the control card. 255=fully CW setting for
				5VDC input. (Not applicable for keypad operation).
	P40	Pot3		The value of RV3 on the control card. 255=fully CW setting for
				5VDC input. (Not applicable for keypad operation).
	P41	DC I/P		0–12V input for load monitoring or phase angle setpoint etc.
	P42	Thermistor		Monitors the Thermistor I/P (standard motor thermistor). The values
				are not all that useful as thermistors act much like a switch.
	P43	4–20mA I/P		Monitors the 4 to 20mA input. Note this input is referenced to the
				PCB 0V and so cannot be used with daisy chained sensors.
	P44	TEMP Trip Level		The value at which Parameter 37 causes a trip.
	P45	4–20mA MAP		Value is the Parameter to which the 4–20mA data is sent.
	P46	4–20mA Set Level		Value is the level at which the 4–20mA level bit will be set.
	P47	DC Input Map		Value is parameter to which the DC input data is sent.
	P48	Set Level DC I/P		Value is the level at which the DC–I/P level bit will be set.
	P49	MAP DAC O/P 1		The value is the parameter that is the source for DAC 1 (0–10VDC).
	P50	MAP DAC O/P 2		The value is the parameter that is the source for DAC 2 (0–10VDC).
