Overview
Chinese variable frequency drives (VFDs). They feature Modbus/RS-485 support.
Model Numbers
- Page 11 (1-3 in the PDF) shows the model number scheme
Wiring Diagram
- Page 24 (2-8 in the PDF) shows the power input/output terminal layout
- Page 26 (2-10 in the PDF) shows the control terminal layout
- Page 27 (2-11 in the PDF) shows an overview of the wiring
- Page 134 (5-30 in the PDF) shows the RS-232/RS-485 wiring
NOTE: the manual lists the RS-485 wiring SG+ and SG- swapped! SG+ is really B- and SG- is really A+, this is the correct RJ12 (6P4C) pinout:
| RJ12 Pin | Function |
|---|---|
| 2 | GND |
| 3 | A+ (manual says SG-!) |
| 4 | B- (manual says SG+!) |
| 5 | +5V |
