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:
"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.
"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
