Protective functions

When the protective function works, the inverter is stopped (output shutoff) by the RDY signal. More Details >>

Output voltage

The output voltage is approximately 300 VDC for the 200 V class and approximately 600 VDC for the 400 V class. 　The output voltage fluctuates due to fluctuat... More Details >>

Encoder feedback control wire

If the phase A and phase B are connected reversely, encoder feedback control is not performed. Instead, the inverter is operated in normal control (V/F contr... More Details >>
