10.94 7 Drive Machine Data (SIMODRIVE Drive MD)
7.1.2 MSD MD (data description - SW 3)
Magnetizing reactance motor 1
171
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 96).
Upper speed Xh characteristic motor 1
172
Default value Lower input limit Upper input limit Units
Depends on motor 100 24 000 rev/min
Active on
Power On
Input of upper speed limit for the Xh characteristic (magnetizing reactance Xn) as specified on
the motor data sheet (non-Siemens motor) or automatic parameterization using machine data
"Motor code number" (MD 96).
In the field-weakening range, the magnetizing reactance Xn 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 Xh characteristic (see diagram MD 175).
Speed at start of field weakening motor 1
173
Default value Lower input limit Upper input limit Units
Depends on motor 100 6 000 rev/min
Active on
Power On
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 96).
In the field-weakening range, the magnetizing reactance Xn 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 Xh characteristic (see diagram MD 175).
Motor maximum speed motor 1
174
Default value Lower input limit Upper input limit Units
Depends on motor 0 20 000 min
Active on
Power On
Input of motor maximum speed as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 96).
