Parameter
Description Data Read/write
P294*
Select Flux Reg
294
Function parameter for selecting the flux specification
when an induction motor is used.
0 = Controlled (closed-loop), flux controller active
1 = Controlled (open-loop), flux controller not active
2 = Controlled (closed-loop), flux controller active, flux
build-up with linear characteristic (smooth magnetization)
when drive is energized. The time characteristic is
determined by the contents of parameter P602 (Excitation
Time).
The smooth magnetization function is only available with
P296=3 (ASM field weakening).

P295
Mod Intervention
295
Connector input for manipulation of the model that is
based on the closed-loop control of the asynchronous
motor.
Index 1: Manipulation of the main inductance
Index 2: Manipulation of the rotor resistance
This intervention option should only be used by experts. It
is possible by intervening in particular in the use of
characteristic blocks to achieve an even greater torque
accuracy in the area of the current model (open-loop
operation).
These inputs are only effective if P296 is set to the value
3 (specialized closed-loop control for asynchronous
motors).

P296*
Dynamic I-Reg
296
Function parameter for selecting the dynamics of the
current controller. The number of sampling steps is
prescribed after which a setpoint step-change is to be fully
corrected.
0 = 2 sampling steps, highest dynamic response
1 = 3 sampling steps, medium dynamic response
2 = 4 sampling steps, lowest dynamic response

P299*
FieldWeakDir
299
Service parameter, only for Siemens service personnel.
This parameter is for special applications ONLY and must
not be changed for standard operation.
Motor speed at which field weakening is applied for
synchronous machines.

P300*
SelectFieldWeak
300
Service parameter, only for Siemens service personnel.
DANGER: This parameter is for special applications
ONLY and must not be changed for standard operation.
Additional protective measures (overvoltage protection)
are required for operating synchronous machines during
field weakening.
