This frequency converter can be used in electric drive control systems for CNC machines, in technological processes of production, as well as in energy management facilities that require precise control of electric motors. The device finds application in ventilation and air conditioning systems, where stable operation of electric drives is needed under varying load conditions. The application of this product is possible in energy complexes and in facilities with high intensity of electricity use, where reliability and precision of control are important. Additionally, the device can be used in transport systems, automated production lines, and industrial robotics, thanks to the versatility of settings and support for various communication protocols.

Veichi AC310 — universal vector VFD for pumps, ventilation, conveyors and machine tools

We call the AC310 the all-rounder of the Veichi range, and that is from field practice, not a slogan. The series runs full vector control (scalar, sensorless vector and closed-loop with encoder), drives both asynchronous and synchronous motors, and is the one we reach for when plain V/f is not enough. If you need to hold torque, pressure or tension rather than just spin a shaft, this is the line.

Its headline feature is a built-in simple PLC (up to 16 steps) plus a PID controller. On a pump station that means the drive holds pressure on its own, with no separate controller. Modbus RTU is standard for an out-of-the-box SCADA tie-in, while Profibus, CANopen and Profinet are optional on the three-phase models.

What the AC310 is for

• Pumps and fans: built-in PID holds pressure/flow, with dedicated pump-and-fan load parameters.
• Single-phase 220 V mains: the T/S2 models run off single-phase 220 V and drive a 3-phase 220 V motor — farms, wells and workshops with no three-phase grid.
• Conveyors, mixers, machine tools: vector torque at low speed where a V/f drive sags.
• Large pump and traction sets: three-phase frames up to hundreds of kW with dual G/P rating.

How the AC310 differs from rivals

Parameter	Veichi AC310	Danfoss FC51	Delta MS300
Built-in PLC	Yes (16 steps)	No	Basic logic
Vector control	Sensorless / encoder	V/f class	Sensorless
Single-phase 220 V input	T/S2 line	Limited	Up to 2.2 kW
Fieldbus	Modbus + options	Modbus	Modbus + options

Honestly, for a simple set-and-forget fan there is no point paying for vector. But the moment you need logic, torque or a SCADA link, the AC310 works out cheaper than a basic drive plus an external controller.

When the AC310 is NOT the right choice

• A simple low-power pump or fan on a budget — the compact Veichi AC10 is cheaper.
• A 380 V motor — the single-phase T/S2 models feed 220 V motors only; you need a three-phase T3 unit.
• Dusty or wet sites — the enclosure is IP20, so it needs a cabinet.

Our experience with the AC310

This is one of our core Veichi series, with steady demand on water utilities and industrial ventilation. Two questions come up most: whether single-phase 220 V will drive a 3-phase motor (yes — that is exactly what the T/S2 models are for) and whether a pump needs a separate PLC (usually not — the built-in PID is enough). If you are unsure whether to pick a G or P frame, get in touch and we will size it to your load.
