7.1.2 MSD MD (data description - SW 3)
Rotor resistance cold motor 2 228
Default value Lower input limit Upper input limit Units
Depends on motor 0 32 767 m
Active on
Power On
Input of rotor resistance (cold) as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 238).
Stator leakage reactance motor 2 229
Default value Lower input limit Upper input limit Units
Depends on motor 0 32 767 m
Active on
Power On
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 238).
Rotor leakage reactance motor 2 230
Default value Lower input limit Upper input limit Units
Depends on motor 0 32 767 m
Active on
Power On
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 238).
Magnetizing reactance motor 2 231
Default value Lower input limit Upper input limit Units
Depends on motor 0 65 535 m
Active on
Power On
Input of magnetizing reactance as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 238).
Upper speed X
h
characteristic motor 2 232
Default value Lower input limit Upper input limit Units
Depends on motor 100 10 000 rev/min
Active on
Power On
Input of the upper speed limit for the X
h
characteristic (magnetizing reactance) as specified on
the motor data sheet (non-Siemens motor) or automatic parameterization using machine data
"Motor code number" (MD 238). In the field-weakening range, the magnetizing reactance X
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 X
h
characteristic (see diagram MD 175).
