PURPOSE:To prevent resonance from being generated along with the change of frequency due to an inverter, by the dip switch of 8 bits and by setting skip frequency and skip width. CONSTITUTION:After a specified connection is carried out on input/output terminals, an inverter is started by a starting switch 13, and trial operation adjustment is started. First, a frequency setting volume switch 15 is slowly turned from the minimum range to the maximum range, and resonance on the load side is checked. The frequency starting the resonance is read out by a digital frequency indicator 17, and the value is set with the dip switch 18 of 8 bits and binary system. By setting the skip frequency and the skip width with the dip switch 18 of 8 bits, resonance is prevented from being generated along with the change of frequency due to the inverter. |
