Dynamic Factor Of Vdc-Max; Control Mode; Continuous Boost; Starting Boost - Siemens SINAMICS V10 Operating Instructions Manual

Par. No. Name
P1243

Dynamic factor of Vdc-max

Defines dynamic factor for DC link controller in [%].
Note:
Vdc controller adjustment is calculated automatically from motor and inverter data.
P1300

Control mode

Controls relationship between speed of motor and voltage supplied by inverter.
Possible settings:
0
1
2
P1310

Continuous boost

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
P1311 will only produce boost during ramping, and is therefore useful for additional torque during acceleration
and deceleration.
P1312

Starting boost

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
Sets pulse frequency of power switches in inverter. The frequency can be changed in steps of 2 kHz.
P1910 Select motor data identification
Performs a motor data identification.
Performs stator resistance measuring.
Possible Settings:
0
1
2
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.
