VFD & Frequency Inverter User Manuals
Forty-seven user manuals — the engineering documentation behind every variable frequency drive (VFD) we supply. The set covers the YD101, YD180, YD201, YD280, YD287, YD580, YD581, YD587, YD680 and YD3000N low-voltage ranges, the YD5000T6N 660 V and YD1000 high-voltage inverters, the YD580E and YD280E permanent-magnet drives, the YDS8000 servo drive, the YDBU brake unit and the DC9000 AFE regenerative unit, plus the OEM manuals for the Trane TL580 VSD, the LG water-cooled AFE and the SPG starter panel. Each manual carries the full parameter list, terminal wiring, commissioning steps and the fault-code table you debug from. Where an English edition exists it is listed first; where only the Chinese edition is published, the English equivalent is sent on request.
