Parameter Description
P299* Service parameter, only for Siemens service personnel.
FieldWeakDir This parameter is for special applications ONLY and must
not be changed for standard operation.
299
Motor speed at which field weakening is applied for
synchronous machines.
In function diagram: 389.2
P300* Service parameter, only for Siemens service personnel.
SelectFieldWeak DANGER: This parameter is for special applications
ONLY and must not be changed for standard operation.
300 Additional protective measures (overvoltage protection)
are required for operating synchronous machines during
field weakening.
Selection of field weakening for synchronous machines
In function diagram: 389.4
P301 Function parameter for setting the smoothing time
Smooth Psi(act) constant for the rotor flux actual value in the EMF model.
301 Precondition:
P296=3 (ASM field weakening)
If the parameter is set to 0 an automatic adjustment of the
smoothing value takes place.
P307 BICO parameter for selecting the binector from which the
SrcEn HC command to enable the harmonic compensation function
is given.
307
P308* Parameter contains the connector for the input signal of
SrcAngleHC harmonic compensation. Usually this parameter is
interconnected with the mechanical (KK0090) or electrical
308 KK0186) angle.
If the parameter is connected to the fixed connector
K0000, harmonic compensation is deactivated.
P309 Function parameter for entering the harmonic in the motor
HC Harmonic torque to be compensated for.
309 With P309=0 compensation is deenergized.
