1.1Introduction to MICROMASTER 420 System Parameters

The layout of the parameter description is as follows.

1 Par number	2 Parameter name			9 Min:	12 Level:
[index]	3 CStat:	5 Datatype	7 Unit:	10 Def:	2
	4 P-Group:	6 active:	8 Quick Comm:	11 Max:
	13	Description:

1.Parameter number

Indicates the relevant parameter number. The numbers used are 4-digit numbers in the range 0000 to 9999. Numbers prefixed with an “r” indicate that the parameter is a “read-only” parameter, which displays a particular value but cannot be changed directly by specifying a different value via this parameter number (in such cases, dashes “-“ are entered at the points “Unit”, “Min”, “Def” and “Max” in the header of the parameter description.

All other parameters are prefixed with a “P”. The values of these parameters can be changed directly in the range indicated by the “Min” and “Max” settings in the header.

[index] indicates that the parameter is an indexed parameter and specifies the number of indices available.

2.Parameter name

Indicates the name of the relevant parameter. Certain parameter names include

the following abbreviated prefixes: BI, BO, CI, and CO followed by a colon. These abbreviations have the following meanings:

BI	=		Binector input, i.e. parameter selects the source of a
		P9999.C

(0)	binary signal

BO = CI =

CO =

r9999

P9999.D

(999:9)

r9999 [99]

Binector output, i.e. parameter connects as a binary signal

Connector input, i.e. parameter selects the source of an analog signal

Connector output, i.e. parameter connects as an analog signal

CO/BO = r9999	Connector/Binector output, i.e. parameter connects as an
r9999	analog signal and/or as a binary signal

To make use of BiCo you will need access to the full parameter list. At this level many new parameter settings are possible, including BiCo functionality. BiCo functionality is a different, more flexible way of setting and combining input and output functions. It can be used in most cases in conjunction with the simple, level 2 settings.

The BiCo system allows complex functions to be programmed. Boolean and mathematical relationships can be set up between inputs (digital, analog, serial etc.) and outputs (inverter current, frequency, analog output, relays, etc.).

3. CStat

Commissioning status of the parameter. Three states are possible:

Commissioning	C
Run	U
Ready to Run	T

This indicates when the parameter can be changed. One, two or all three states may be specified. If all three states are specified, this means that it is possible to change this parameter setting in all three inverter states

1Quick commissioning

2Inverter

29Download

30Factory setting

Dependency:

Reset to 0 for inverter to run.

P0003 (user access level) also determines access to parameters.

Note:

P0010 = 1

The inverter can be commissioned very quickly and easily by setting P0010 = 1. After that only the important parameters (e.g.: P0304, P0305, etc.) are visible. The value of these parameters must be entered one after the other. The end of quick commissioning and the start of internal calculation will be done by setting P3900 = 1 - 3. Afterward parameter P0010 will be reset to zero automatically.

P0010 = 2

For service purposes only.

P0010 = 29

To transfer a parameter file via PC tool (e.g.: DriveMonitor, STARTER) parameter P0010 will be set to 29 by the PC tool. When download has been finished PC tool resets parameter P0010 to zero.

P0010 = 30

	When resetting the parameters of inverter P0010 must be set to 30. Resetting of the parameters will be
	started by setting parameter P0970 = 1. The inverter will automatically reset all its parameters to their
	default settings. This can prove beneficial if you experience problems during parameter setup and wish to
	start again. Duration of factory setting will take about 60 s.
	If P3900 is not 0 (0 is the default value), this parameter is automatically reset to 0.

	P-Group:	FUNC	Active: first confirm	QuickComm. No	Max:	65535

Defines a limited set of parameters to which the end user will have access.

Instructions for use:

Step 1: Set P0003 = 3 (expert user)

Step 2: Go to P0013 indices 0 to 16 (user list)

Step 3: Enter into P0013 index 0 to 16 the parameters required to be visible in the user-defined list. The following values are fixed and cannot be changed:

-P0013 index 19 = 12 (key for user defined parameter)

-P0013 index 18 = 10 (commissioning parameter filter)

-P0013 index 17 = 3 (user access level)

Step 4: Set P0003 = 0 to activate the user defined parameter.

Index:

P0013[0] : 1st user parameter P0013[1] : 2nd user parameter P0013[2] : 3rd user parameter P0013[3] : 4th user parameter P0013[4] : 5th user parameter P0013[5] : 6th user parameter P0013[6] : 7th user parameter P0013[7] : 8th user parameter P0013[8] : 9th user parameter P0013[9] : 10th user parameter P0013[10] : 11th user parameter P0013[11] : 12th user parameter P0013[12] : 13th user parameter P0013[13] : 14th user parameter P0013[14] : 15th user parameter P0013[15] : 16th user parameter P0013[16] : 17th user parameter P0013[17] : 18th user parameter P0013[18] : 19th user parameter P0013[19] : 20th user parameter

Dependency:

First, set P0011 ("lock") to a different value than P0012 ("key") to prevent changes to user-defined parameter. Then, set P0003 to 0 to activate the user-defined list.

When locked and the user-defined parameter is activated, the only way to exit the user-defined parameter (and view other parameters) is to set P0012 ("key") to the value in P0011 ("lock").

Note:

Alternatively, set P0010 = 30 (commissioning parameter filter = factory setting) and P0970 = 1 (factory reset) to perform a complete factory reset.

	The default values of P0011 ("lock") and P0012 ("key") are the same.

r0067		CO: Act. output current limit			Min:	-		Level:
			Datatype: Float	Unit: A	Def:	-		3
		P-Group:	CONTROL		Max:	-

Displays valid maximum output current of inverter.

This value is influenced by P0640 (max. output current), the derating characteristics and the thermal motor and inverter protection.

Dependency:

P0610 (motor I2t temperature reaction) defines reaction when limit is reached.

Note:

	Normally, current limit = rated motor current (P0305) x motor current limit (P0640). It is less than or equal to
	maximum inverter current.
	The current limit may be reduced if the motor thermal model calculation indicates that overheating will
	occur.

	P-Group:	QUICK	Active: first confirm	QuickComm. Yes	Max:	2

Determines whether power settings (e.g. nominal rating plate power - P0307) are expressed in [kW] or [hp].

The default settings for the nominal rating plate frequency (P0310) and maximum motor frequency (P1082) are also set automatically here, in addition to reference frequency (P2000).

Possible Settings:
0	Europe [kW],	frequency default 50 Hz

1North America [hp], frequency default 60 Hz

2	North America [kW], frequency default 60 Hz
Dependency:

The setting of DIP switch 2 determines the validity of settings 0 and 1 for P0100 according to the diagram below:

R	e m	o v e S D	P			DIP2
		Power				Quick
						commissioning
		cycle
						P0010 = 1
		P0100 = 2		yes	yes	P0100 = 2
		?				?
		no				no
					no	P0100 = 1
						?
				no		yes
	DIP2 = OFF
		?
		yes

Power in kW		Power in kW		Power in hp
50 Hz		60 Hz		60 Hz
P0100 = 0		P0100 = 2		P0100 = 1

Stop drive first (i.e. disable all pulses) before you change this parameter.

P0010 = 1 (commissioning mode) enables changes to be made.

Changing P0100 resets all rated motor parameters as well as other parameters that depend on the rated motor parameters (see P0340 - calculation of motor parameters).

Notice:

P0100 setting 2 (==> [kW], frequency default 60 [Hz]) is not overwritten by the setting of DIP switch 2 (see diagram above).

Optimizes Vdc controller, which extends the ramp-down time if regenerative energy from motor would otherwise cause DC link overvoltage trips.

Reducing the value enables controller to cut in earlier and reduce the risk of overvoltage.

Dependency:

Set P1254 ("Auto detect Vdc switch-on levels") = 0. Cut-in levels for Vdc-controller and compound braking are then derived directly from P0210 (supply voltage).

Vdc_max switch-on level	= 1.15	2 P0210
Compound braking switch-on level	= 1.13	2 P0210

Note:

If mains voltage is higher than value entered, automatic deactivation of the Vdc controller may occur to avoid acceleration of the motor. An alarm will be issued in this case (A0910).

Default value is dependant on inverter rated power.

Reduction of output frequency is usually only effective if the load is also reduced. This is for example valid for variable torque applications with a quadratic torque characteristic as pumps or fans.

A trip will always result eventually, if the action taken does not sufficiently reduce internal temperature.

The pulse frequency is normally reduced only if higher than 2 kHz (see P0291 - configuration of inverter protection).

Stator resistance value in [Ohms] for connected motor (from line-to-line). The parameter value includes the cable resistance.

There are three ways to determine the value for this parameter: 1. Calculate using

P0340 = 1 (data entered from rating plate) or

2.Measure using P1910 = 1 (motor data identification - value for stator resistance is overwritten).

3.Measure manually using an Ohmmeter.

Note:

Since measured line-to-line, this value may appear to be higher (up to 2 times higher) than expected. The value entered in P0350 (stator resistance) is the one obtained by the method last used.

P0610	Motor I2t temperature reaction				Min:	0	Level:
	CStat:	CT	Datatype: U16	Unit: -	Def:	2	3
	P-Group:	MOTOR	Active: first confirm	QuickComm. No	Max:	2

Defines reaction when motor I2t reaches warning threshold.

Possible Settings:

0No reaction, warning only

1Warning and Imax reduction (results in reduced output frequency)

2	Warning and trip (F0011)
Dependency:

Trip level = P0614 (motor I2t overload warning level) * 110 %

Note:

The purpose of motor I²t is to calculate or measure the motor temperature and disable the inverter if the motor is in danger of overheating.

The motor temperature will be dependent on many factors, including the size of the motor, the ambient temperature, the previous history of the loading of the motor, and of course, the load current. (The square of the current actually determines the heating of the motor and the temperature rises with time - hence I²t).

Because most motors are cooled by built in fans running at motor speed, the speed of the motor is also important. Clearly a motor running at high current (maybe due to boost) and a low speed, will overheat more quickly than one running at 50 or 60 Hz, full load. The MM4 take account of these factors.

The drives also include inverter I²t protection (i.e. overheating protection, see P0290) in order to protect the units themselves. This operates independently of the motor I²t, and is not described here.

I²t operation:

The measured motor current (r0027) is compared with the rated motor current (P0305), and other motor parameters (P0304, P0307, etc.), and the temperature of the motor calculated, a calculation which also includes the output frequency (motor speed) to account for fan cooling. If parameter P0335 is changed to indicate a forced cooled motor, the calculation is modified accordingly.

Where parameters are not entered by the user, such as P0344 (motor weight), a calculated value will be used based on a Siemens motor. If required, the motor time constant can be adjusted using P0611, in effect overwriting the calculated value.

The resulting temperature is displayed in % of maximum temperature in r0034. When this value reaches the value set in P0614 (default 100%), a warning A0511 occurs. If no action is taken and the temperature reaches 110%, then the inverter trips, showing F0011. The reaction to the warning can be changed from this default using P0610; for example, the drive can react as though a current limit has occurred, or a fault forced immediately. The warning level of P0614 can also be adjusted to raise and lower the warning or trip level as required.

Parameter r0034 is particularly useful to monitor if the calculated motor temperature is rising excessively.

	P-Group:	MOTOR	Active: Immediately	QuickComm. No	Max:	16000

Defines motor thermal time constant and is calculated automatically from the motor data (see P0340).

Notice:

A larger number increases the time taken for the calculated motor temperature to change. Default value is dependant on inverter rated power.

Defines the [%] value at which alarm A0511 (motor overtemperature) is generated.

Motor I2t calculation is used to estimate a maximum tolerable period (i.e. without overheating) for motor overload. The I2t calculation value is deemed = 100 % when this maximum tolerable period is reached (see r0034).

Dependency:

A motor over-temperature trip (F0011) is produced at 110 % of this level.
