Control Modes (P1300) - Siemens MICROMASTER 430 Operating Instructions Manual

Issue 10/06
4.3.5 Compound braking
Compound braking is possible with OFF1 and OFF3. In the case of compound
braking, a DC component is superimposed on the alternating current.
Set braking current :

Control modes (P1300)

MICROMASTER 430 has a number of different control modes based on U/f-
control. The individual modes have been listed below, additional settings are listed
in the parameter list and the function plans contained therein.
Linear U/f control
Can be used for variable and constant torque applications e.g. transport
systems and positive displacement pumps.
Linear U/f control with flux current control (FCC)
This type of control can be used to improve the performance and dynamic
behaviour of the motor.
Parabolic U/f control
This type of control can be used for variable torque loads e.g. fan and pumps.
Multiple point U/f control
Please refer to the MICROMASTER 430 parameter list for more information on
this operating mode.
U/f control for textile applications
There is no slip compensation gain or resonance dampening. The Imax
controller refers to voltage instead of frequency.
U/f control with FCC for textile applications
A combination of P1300 = 1 and P1300 = 5.
U/f control with independent voltage set point
Using the P1330, the voltage set point can be given independently from the
starting frequency of the ramp function generator (HLG).
