8.8 Motor data - characteristic curves
The possible characteristic curves with which the motors can be operated are explained in the
following. The nameplate data of the motor is relevant for operation with the 50 Hz or 87 Hz
characteristic curve (

Section 4.1 "Factory settings"). The use of specially calculated motor data is
required for operation with a 100 Hz characteristic curve (

Section 8.8.3 "100 Hz characteristic
curve (only 400 V devices)").

8.8.1 50 Hz characteristic curve
(

Variation 1:10)
The motor used for 50 Hz operation can be
operated up to its rated point at 50 Hz with
nominal torque. Operation above 50 Hz is
possible, however the output torque reduces
in a non-linear manner (see following
diagram). Above the rated point, the motor
enters its field weakening range, since the
voltage cannot be increased beyond the
value of the line voltage when the frequency
is increased above 50 Hz.
