SFU 0303 Frequency Converter
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, weakened field, field suppression:
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.
Caution:
If using this autotuning, damages at spindles or the converter are part of
warranty, due to possible wrong input values.
