07.97 7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
Stator leakage reactance
1139
Default value Lower input limit Upper input limit Units
0.0 0.0 100.0
Active
at once*
Input of stator leakage reactance as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 1102).
Note:
This data is relevant only for MSD drives.
* Active on "Power On" until SW < 6
Rotor leakage reactance
1140
Default value Lower input limit Upper input limit Units
0.0 0.0 100.0
Active
at once*
Input of rotor leakage reactance as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 1102).
Note:
This data is relevant only for MSD drives.
* Active on "Power On" until SW < 6
Magnetizing reactance
1141
Default value Lower input limit Upper input limit Units
0.0 0.0 1 000.0
Active
at once*
Input of magnetizing reactance as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 1102).
Note:
This data is relevant only for MSD drives.
* Active on "Power On" until SW < 6
Speed at start of field weakening
1142
Default value Lower input limit Upper input limit Units
0.0 0.0 50 000.0 rev/min
Active
at once*
Input of speed at which field weakening starts as specified on the motor data sheet (non-
Siemens motor) or automatic parameterization using machine data "Motor code number"
(MD 1102). In the field-weakening range, the magnetizing inductivity L
h
increases linearly from
the saturated value at the speed at which field weakening begins to the unsaturated value at
the upper limit speed of the L
h
characteristic (see diagram MD 1144).
Note:
This data is relevant only for MSD drives.
* Active on "Power On" until SW < 6
