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 X
h
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 X
h
characteristic (magnetizing reactance X
n
) 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 X
n
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).
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 X
n
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).
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).
