9.8.3 100Hz characteristic curve (only 400 V devices)
( Variation 01:20:00)
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 are required (see
below) that differ 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.
The following data refer to a 230/400 V motor
winding. They apply for IE1 or IE2 motors. It should be noted that these details may deviate slightly, as
motors are subject to certain manufacturing tolerances. It is recommended that the resistance of the
connected motor is measured by the frequency inverter (P208 / P220).
