SED2 Operation and Maintenance Manual
118 Siemens Building Technologies, Inc
r1801 CO: Act. switching frequency
Min: - Def: - Max: -
Level 3
Note:
Actual pulse frequency of power switches in inverter. Under certain conditions (inverter overtemperature, see P0290), this
can differ from the values selected in P1800 (pulse frequency).
P1820 Reverse output phase sequence
Min: 0 Def: 0 Max: 1
Level 2
Enum:
0=OFF
1=ON
Dependency:
If positive and negative revolution is enabled, frequency setpoint is directly used.
If both positive and negative revolution are disabled, reference value is set to zero.
Details:
See P1000 (select frequency setpoint).
P1910 Select motor data identification
Min: 0 Def: 0 Max: 20
Level 2
Settings:
P1910=1: All motor data
* P0350 stator resistance,
* P0354 rotor resistance,
* P0356 stator leakage reactance,
* P0358 rotor leakage reactance,
* P0360 main reactance
will be identified and parameter will be changed.
P1910=3: Saturation curve
* P0362 ... P0365 magnetizing curve flux 1 .. 4
* P0366 ... P0369 magnetizing curve imag 1 .. 4
will be identified and parameter will be changed.
Enum:
0=Disabled
1=Identification of all parameters with parameter change
2=Identification of all parameters without parameter change
3=Identification of saturation curve with parameter change
4=Identification of saturation curve without parameter
change
5=Identification of XsigDyn (r1920) without parameter
change
6=Identification of Tdead (r1926) without parameter change
7=Identification of Rs (r1912 ) without parameter change
8=Identification of Xs (r1915) without parameter change
9=Identification of Tr (r1913) without parameter change
10 =Identification of Xsigma (r1914) without parameter
change
20 =Set voltage vector
Dependency:
No measurement if motor data incorrect.
P1910=1 : Calculated value for stator resistance (see P0350) is overwritten.
P1910=2 : Values already calculated are not overwritten.
Note:
Before selecting motor data identification, "Quick commissioning" has to be performed in advance.
Once enabled (P1910=1), A0541 generates a warning that the next ON command will initiate measurement of motor
parameters.
When choosing the setting for measurement, observe the following:
1. "With parameter change" means that the value is actually adopted as P0350 parameter setting and applied to the
control as well as being shown in the read-only parameters below.
2. "Without parameter change" means that the value is only displayed, that is, shown for checking purposes in the read-
only parameter r1912 (identified stator resistance). The value is not applied to the control.
r1912[3] Identified stator resistance
Min: - Def: - Max: -
Level 2
Index:
r1912[0] : U_phase r1912[1] : V_phase r1912[2] : W_phase
Note:
This value is measured using P1910=1 or 2 , that is, identification of all parameters with/without change.
P2000 Reference frequency
Min: 1.00 Def: 50.00 Max: 650.00
Level 2
P2001 Reference voltage
Min: 10 Def: 1000 Max: 2000
Level 3
Example:
P0201=230 specifies that 4000H received via USS denotes 230V.
P2002 Reference current
Min: 0.10 Def: 0.10 Max: 10000.00
Level 3
r2004 Reference power
Min: - Def: - Max: -
Level 3
P2009[2] USS normalization
Min: 0 Def: 0 Max: 1
Level 3
Enum:
0=Disabled 1=Enabled
Index:
P2009[0] : Serial interface COM link P2009[1] : Serial interface BOP link
Note:
If enabled, the main setpoint (word 2 in PZD) is not interpreted as 100%=4000H, but as "absolute" instead (for example,
4000H=16384 means 163.84 Hz ).
