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 Lh 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 Lh characteristic (see diagram MD 1144).
Note:
This data is relevant only for MSD drives.
* Active on "Power On" until SW < 6
