P1243
Dynamic factor of Vdc-max
10 - 200
100
%
Defines dynamic factor for DC link controller in [%].
Note:
Vdc controller adjustment is calculated automatically from motor and inverter data.
P1300
Control mode
0 - 2
0
--
Controls relationship between speed of motor and voltage supplied by inverter.
Possible settings:
0
V/f with linear characteristic
1
V/f with FCC
2
V/f with parabolic characteristic
P1310
Continuous boost
0.0 - 250.0
50.0
%
P1310 causes a voltage boost depending on the output frequency. At low output frequencies, the output
voltage is low to keep the flux level constant. However, the output voltage may be too low
● for magnetization the asynchronous motor
● for hold the load
● to overcome losses in the system.
P1311
Acceleration boost
0.0 - 250.0
0.0
%
P1311 will only produce boost during ramping, and is therefore useful for additional torque during acceleration
and deceleration.
P1312
Starting boost
0.0 - 250.0
0.0
%
Applies a constant linear offset (in [%] relative to P0305 (rated motor current)) to active V/f curve (either linear
or quadratic) after an ON command and is active until
1) ramp output reaches setpoint for the first time respectively
2) setpoint is reduced to less than present ramp output
This is useful for starting loads with high inertia.
Setting the starting boost (P1312) too high will cause the inverter to limit the current, which will in turn restrict
the output frequency.
P1800
Pulse frequency
2 - 16
4
kHz
Sets pulse frequency of power switches in inverter. The frequency can be changed in steps of 2 kHz.
P1910
Select motor data identification
0 - 2
0
--
Performs a motor data identification.
Performs stator resistance measuring.
Possible Settings:
0
Disabled
1
Identification of Rs with parameter change
2
Identification of Rs without parameter change
Dependency:
No measurement if motor data are incorrect.
P1910 = 1: Calculated value for stator resistance (see P0350) is overwritten.
P1910 = 2: Values already calculated are not overwritten.
Note:
If the motor data identification routine is activated (e.g. P1910 = 1), then at the next ON command, the
measuring operation is stared and alarm A0541 is generated. After the measurement is completed, both
P1910 and the alarm are reset.
