7.7 Motor / characteristic curve parameters

Parameter Setting value / Description / Note
Supervisor
Parameter
set
Available with option
P203 Nominal current
S P
Always available
0.01 ... 20.00 A
[***] The nominal current is a decisive parameter for the current vector control.
P204 Nominal voltage
S P
Always available
100 ... 800 V
[***] The >Nominal voltage< matches the mains voltage to the motor voltage. In combination with the
nominal frequency, the voltage/frequency characteristic curve is produced.
P205 Nominal power
S P
Always available
0 ... 11 kW
[***] The motor nominal power controls the motor set via P200. The output is always shown in "kW" even
if a motor with "HP" is selected in P200.
P206 Cos
ϕ
S P
Always available
0.50 ... 0.90
[***] The cos ϕ is a decisive parameter for the current vector control.
P207 Star Delta Connection
S P
Always available
0...1
[***] 0 = Star
1 = Delta
The motor circuit is decisive for stator resistance measurement and therefore for current vector
control.
P208 Stator resistance
S P
Always available
0.00 ... 300.00 Ω
[***]
Motor stator resistance ⇒ resistance of one line in the 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.
For simple measurement, this parameter can be set to "Zero". Pressing the ENTER key initiates the
automatic measurement between two motor phases. In the FI, the resistance on the line is measured
on the basis of the delta or star circuit (P207) and the value saved.
Note: For correct function of the current vector control, the stator resistance must be
automatically measured by the FI.
P209 No load current
S P
Always available
0.01 ... 20.00 A
[***] 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.
*** These settings are dependent on the selection in parameter 200.
