Siemens 440 manual P20013 Reference voltage, 193, Normalization, Limitation

Issue 01/06 Parameter Description

Caution:

Parameter P2000 represents the reference frequency of the above mentioned interfaces. A maximum frequency setpoint of 2*P2000 can be applied via the corresponding interface. Unlike parameter P1082 (Max. Frequency) this limits the inverter frequency internally independent of the reference frequency. By modification of P2000 it will also adapt the parameter to the new settings.

Limitation

f_act,limit = min(P1082, f_act)

Notice:

Reference variables are intended as an aid to presenting setpoint and actual value signals in a uniform manner. This also applies to fixed settings entered as a precentage. A value of 100 % (USS / CB) corresponds to a process data value of 4000H, or 4000 0000H in the case of double values.

In this respect, the following parameters are available:

P2000	Reference frequency	Hz
P2001	Reference voltage	V
P2002	Reference current	A
P2003	Reference torque	Nm
P2004	Reference power	kW	f(P0100)
		hp

P2001[3] Reference voltage					Min:	10	Level
	CStat:	CT	Datatype: U16	Unit: V	Def:	1000	3
	P-Group:	COMM	Active: first confirm	QuickComm.: No	Max:	2000

Full-scale output voltage (i.e. 100 % ) used over serial link (corresponds to 4000H).

Index:

P2001[0] : 1st. Drive data set (DDS)

P2001[1] : 2nd. Drive data set (DDS)

P2001[2] : 3rd. Drive data set (DDS)

Example:

P2001 = 230 specifies that 4000H received via USS denotes 230 V.

If a BICO connection is made between two parameters, the "unit" of the parameters (standardized (Hex) or physical (i.e. V) values) may differ. MICROMASTER implicitly makes an automatic conversion to the target value.
