P207
Motor circuit
(Motor circuit)
S P
0 ... 1
{ see information } 0 = star 1 = delta
The motor circuit is decisive for stator resistance measurement (P220) and therefore critical for
current vector control.
Information
Default setting
The default setting is dependent upon the FI nominal power and the setting in P200.
P208
Stator resistance
(Stator resistance )
S P
0.00 ... 300.00
W
{ see information }
Motor stator resistance ⇒ resistance of a phase winding with a DC motor.
Has a direct influence on the current control of the FI. Too high a value will lead to a possible
overcurrent; too low a value to a motor torque that is too low.
The parameter P220 can be used for simple measurement. Parameter P208 can be used for
manual setting or as information about the result of an automatic measurement.
NOTE:
For optimum functioning of the current vector control, the stator resistance must be automatically
measured by the FI.
Information
Default setting
The default setting is dependent upon the FI nominal power and the setting in P200.
P209
No load current
(No load current)
S P
0.0 ... 1000.0 A
{ see information } This value is always calculated automatically from the motor data if there is a change in the
parameter >cos ϕ < P206 and the parameter >Nominal current< P203.
NOTE: If the value is to be entered directly, then it must be set as the last motor data. This is
the only way to ensure that the value will not be overwritten.
Information
Default setting
The default setting is dependent upon the FI nominal power and the setting in P200.
P210
Static boost
(Static boost)
S P
0 ... 400 %
{ 100 } The static boost affects the current that generates the magnetic field. This is equivalent to the no
load current of the respective motor and is therefore load-independent. The no load current is
calculated using the motor data. The factory setting of 100% is sufficient for normal applications.
