7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
1119
Default value
0.0
A series reactor is usually required for stable operation of the current controller on high-speed
special asynchronous motors or low-leakage asynchronous motors. In this way the inductance
of the reactor is taken into account in the current model.
Note:
This machine data only applies to main spindle drives.
1120
Default value
10.0
Input of proportional gain of current controller or automatic parameterization (initialization)
through operator action Calulate controller data.
1121
Default value
2000.0
Input of control quantity "Integral-action time of current controller" or automatic
parameterization (initialization) through operator action Calulate controller data.
Note:
Integral arm can be disabled by entering the value T
1124
Symmetr. ref. model current control loop (up to SW 4)
Default value
0.5
Input of the symmetrizing possibility for the reference model current control loop. This machine
data emulates the calculation deadtime of the current control loop. The emulation is calculated
as approximation of a broken deadtime (see graphic representation MD 1416). This allows the
behaviour of the reference model to be adapted to the controlled system behaviour of the clo-
sed P-controlled current control loop.
Caution:
This machine data is only relevant for Siemens-internal purposes and must not be modified.
