10.3 Motor data rated point 100Hz (400V devices only)
( Æ Adjustment range 1:10)
An operating point 100 Hz/400V 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.
NOTE: The following motor data applies to standard motors with 230V/400V windings.
