8.8.3 100 Hz characteristic curve (only 400 V devices)
( Variation 01:20)
An operating point 100 Hz/400
V can be
selected for a greater speed adjustment
range with up to a ratio of 1:20. Special
motor data is required in this case (see
below) that differs from the normal 50 Hz
data. It must be ensured in this case that a
constant torque is generated across the
entire adjustment range but that it is smaller
than the nominal torque for 50 Hz operation.
The advantage, in addition to the greater
speed adjustment range, is the improved
motor temperature behaviour. An external
fan is not absolutely essential for smaller
output speed ranges.

NOTE: The following motor data applies for standard motors with a 230 / 400 V winding. It must
be noted that this information may change slightly because the motors are subject to certain
tolerances. It is recommended that the resistance of the connected motor is measured by the
frequency inverter (P208 / P220).
