Baldor mn722 Converter Control Board Parameter Definitions, Block Title Parameter Description

	Table 4-2	Converter Control Board Parameter Definitions
Block Title	Parameter	Description
MISC	Factory Settings	Restores factory settings for converter section parameters. Select YES and press
		ENTER to restore factory parameter values. The Keypad Display will show
		“Operation Done” then return to “NO” when complete.
	Line Inductor	The value of the internal or external boost regulator inductor in “mH”. This parameter
	(Boost	sets the current loop gain of the converter section. This value is factory set and
	Regulator)	should not require adjustment.
	Bus Capacitance	Sets the nominal DC Bus capacitance. This parameter sets the voltage loop gain for the
		converter section. This value is factory set and should not require adjustment unless
		more capacitance or more controls are added across the DC Bus.
	DAC Selection	This parameter configures both Analog Outputs #1 (J1-6) and #2 (J1-7) at the same time
		for troubleshooting purposes.
		AB BC Cross- This selection provides a scaled 0-5VDC signals at Outputs #1 and #2.
			Analog Output #1 represents the Line-Line voltage (L1–L2).
			Analog Output #2 represents the Line-Line voltage (L2–L3).
		DQ CONTRLR- This selection provides a scaled 0-5VDC signals at Outputs #1 and #2.
			Analog Output #1 represents the Direct Control voltage.
			Analog Output #2 represents the Quadrature Control voltage.
		DQ Currents- This selection provides a scaled 0-5VDC signals at Outputs #1 and #2.
			Analog Output #1 represents the Direct Control current.
			Analog Output #2 represents the Quadrature Control current.
		IQ Command- This selection provides a scaled 0-5VDC signals at Outputs #1 and #2.
			Analog Output #1 represents the Quadrature Command signal.
			Analog Output #2 represents the Quadrature Feedback signal.
		IB and IC-	This selection provides a scaled 0-5VDC signals at Outputs #1 and #2.
			Analog Output #1 represents the Phase B current feedback.
			Analog Output #2 represents the Phase C current feedback.
		Va and Vb- This selection provides a scaled 0-5VDC signals at Outputs #1 and #2.
			Analog Output #1 represents the PWM voltage for Phase A.
			Analog Output #2 represents the PWM voltage for Phase B.
		Ia and Ib-	This selection provides a scaled 0-5VDC signals at Outputs #1 and #2.
			Analog Output #1 represents Phase A current.
			Analog Output #2 represents Phase B current.
SECURITY	Security State	Off - No security Access Code required to change parameter values.
CONTROL		Local - Requires security Access Code to be entered (using the keypad) before
		parameter changes can be made using the Keypad.
		Serial - Requires security Access Code to be entered (over the Serial Link) before
		parameter changes can be made using the Serial Link.
		Total - Requires security Access Code to be entered (using Keypad or Serial Link)
		before parameter changes can be made using the Keypad or serial link.
		Note: If security is set to Local, Serial or Total you can press PROG and scroll
			through the parameter values and view their values but you are not allowed
			to change their values unless you enter the correct access code.
	Access Timeout	The time in seconds the security access remains enabled after leaving the programming
		mode. If you exit and go back into the program Mode within this time limit, the
		security Access Code does not have to be re-entered. This timer starts when leaving
		the Program Mode (by pressing DISP).
		Note: This feature is not available when using the Serial operating mode or if
			power is cycled.
	Access Code	A 4 digit number code. Only persons that know the code can change secured Level 1
		and Level 2 parameter values.
		Note: Please record your access code and store it in a safe place. If you cannot
			gain entry into parameter values to change a protected parameter, please
			contact Baldor. Be prepared to give the 5 digit code shown on the lower
			right side of the Keypad Display at the Security Control Access Code
			parameter prompt.
