Siemens 440 manual R0206 Rated inverter power kW / hp, R02073 Rated inverter current

Parameter Description Issue 01/06

It is recommended to modify P0205 first. Afterwards motor parameter may be adapted. Motor parameter will be overridden by changing this sequence.

Notice:

-The parameter value is not reset by the factory setting (see P0970).

-To set P0205 = 1 (variable torque) is not possible for all inverters.

-Use setting 1 (variable torque) only for variable-torque applications (e.g. pumps and fans). If used for constant-load applications, I2t warning will be produced too late, causing overheating in the motor.

r0206	Rated inverter power [kW] / [hp]		Min:	-
	Datatype: Float	Unit: -	Def:	-
	P-Group: INVERTER		Max:	-

Level

2

Displays nominal rated motor power from inverter.

Dependency:

Value is displayed in [kW] or [hp] depending on setting for P0100 (operation for Europe / North America).

r0206[hp] = 0.75 ⋅ r0206[kW]

r0207[3]	Rated inverter current		Min:	-	Level
	Datatype: Float	Unit: A	Def:	-	2
	P-Group: INVERTER		Max:	-

Indicates the rated inverter current.

Index:

r0207[0] : Rated inverter current

r0207[1] : Rated VT current

r0207[2] : Rated CT current

Note:

VT (variable torque) and CT (constant torque) specify the overload capability (CT/VT application) of the inverter. The definition of the rated as well as the overload and base load values depend on the inverter type and inverter power. The different values can be taken from the appropriate Catalog or are saved in the drive inverter (refer to Fig.).

The VT rated current r0207[1] or CT rated current r0207[2] represent the matching 4-pole Siemens IEC standard motor for the selected load duty cycle (refer to the diagram). Parameters r0207[1] or r0207[2] are used as default values for P0305 as a function of the CT/VT application (load duty cycle). If r0207[1] = r0207[2], then it is not possible to make a differentiation between a CT/VT application.

Overload in operation is only possible if, before the overload condition, the load current was less than the rated current. For drives, which must be able to handle overload conditions, it is first necessary to define a base load current for the required load.

If the full overload capability is used, then this is detected using an I²t monitoring and the power module is protected as a function of parameter P0290.

r0208	Rated inverter voltage		Min:	-
	Datatype: U32	Unit: V	Def:	-

Value:

r0208 = 230 : 200 - 240 V +/- 10 %

r0208 = 400 : 380 - 480 V +/- 10 %

r0208 = 575 : 500 - 600 V +/- 10 %
