This series is the first generation of AC motor drive with abundant features, including multi-function I/O terminal, V/f control and auto-torque/auto-slip compensation, built-in RS-485 serial interface (MODBUS) and digital keypad that can be connected to VFD with extended wire. Now it has been updated to B and M series. Applications: Air conditioner for large buildings, woodcarving machine, wastewater treatment system, washing machine, vertical stamping machines, compressor, circular loom, flat knitting machine, pasta machine, etc.
