Frequenzumrichter
Example 1, normal adjustment:
A 2-pole motor with a maximum rotational speed of 30.000rpm needs at this point a nominal voltage of 220V
at a current of 5A .
Example 2, operation in field weakening:
A 2-pole motor with a maximum rotational speed of 30.000rpm needs at 20.000rpm a nominal voltage of
220V at a current of 5A . But the voltage cannot be raised further, so the desired speed can be achieved but
with reduced power.
The current limit, in this case 8A, indicates the S6 mode, where it is 5A as the nominal current for the
S1 mode.
The acceleration values (Ramp up/down) should be setup to be 12000rpm/sec. It has to be ensured
that the shaft can rotate freely.
Start the automatic and save the characteristic after having finished the procedure. Download it into
the converter.
ATTENTION:
If using this autotuning, damages at spindles or the converter due to possible wrong
input values are not part of any warranty.
