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
1140
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
1141
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
1142
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
the saturated value at the speed at which field weakening begins to the unsaturated value at
the upper limit speed of the L
