AC Drives (VFD)

VEICHI AC310

The general-purpose workhorse, 0.75 kW to 1,120 kW

Veichi's mainstream vector drive and the right default for most applications. A book-style narrow body cuts panel volume by up to 60 percent while still driving asynchronous, synchronous and synchronous reluctance motors from the same unit.

Power range

0.75-1,120 kW

Voltage

1ph 220 V, 3ph 220 V (to 220 kW); 3ph 380 V (to 1,120 kW)

Control modes

V/F, open-loop vector, closed-loop vector

Communication

Modbus-RTU standard; PROFIBUS-DP, CANopen, PROFINET, Modbus-TCP optional

Protection

IP20, forced air cooling

Safety

SIL3 Safe Torque Off (STO)

VEICHI AC600

Full-topology flagship with on-line health monitoring

The top of the low-voltage range. One control platform drives almost anything with a shaft - induction, PM synchronous, reluctance, spindle, torque and linear motors - and a built-in PHM system watches IGBT and capacitor condition in real time, so you can plan a replacement rather than discover one.

Motor types

Asynchronous, VF, AC servo, PMSM, synchronous reluctance, high-speed synchronous, spindle, torque, linear

Control modes

V/F, SVC, FVC, V-F split control

Expansion

3x SPI expansion slots on the control board

Safety

Optional Safe Torque Off (STO)

Cooling

Separated component and heatsink ducts, forced air

Veichi does not publish a single power table for the AC600 - ratings are configured to the application. Send us your motor data and we will size it.

VEICHI AC600F

IP66 washdown and outdoor drive, 0.75 kW to 22 kW

An AC600 in a sealed, UV-resistant polycarbonate housing rated IP66 - mountable on the machine instead of in a panel, and built to survive hose-down cleaning, dust and direct weather. Holds 200 percent of rated torque at 0.0 Hz in closed-loop vector mode.

Power range

0.75-22 kW

Protection

IP66, UV-resistant PC housing

Input tolerance

+/-15% of rated voltage

Control modes

V/F, SVC, FVC, V-F split control

Communication

PROFIBUS, PROFINET, EtherCAT, EtherNet/IP

Safety

SIL3 Safe Torque Off (STO), optional mechanical disconnect

VEICHI AC200

High-power vector control to 710 kW, up to 1140 V

Where the AC310 stops, the AC200 keeps going - 660 V and 1140 V classes for mining, metallurgy and heavy plant. Open-loop starting torque of 150 percent at 0.5 Hz, or 200 percent at 0 Hz closed loop, and an over-excitation function that often removes the need for a braking resistor entirely.

Power range

0.4-710 kW

Voltage

1ph/3ph 220 V (0.4-220 kW); 3ph 380 V (0.75-710 kW); 3ph 660 V (7.5-710 kW); 3ph 1140 V (37-710 kW)

Control modes

V/F and vector, each with or without PG feedback

Communication

RS485; PROFIBUS-DP, CAN, CANopen via expansion card

Output frequency

Up to 599 Hz under vector control

VEICHI AC330

Purpose-built for synchronous reluctance motors

A dedicated vector platform for SynRM motors, where a general-purpose drive leaves efficiency on the table. Veichi measures roughly 40 percent lower system losses against an asynchronous equivalent running under its rating - the case that matters for fans, pumps and compressors that spend their life part-loaded.

Voltage

S2: 1ph 200-240 V / T2: 3ph 200-240 V / T3: 3ph 380-480 V / T6: 3ph 660-690 V

Output frequency

0-599 Hz

Overload

150-200% of rated current (G-type)

Motor types

Synchronous reluctance, induction, PM synchronous

Control modes

V/F, open-loop vector, closed-loop vector; 50:1 speed regulation on reluctance motors

Communication

RS485 standard; 2x SPI high-speed expansion channels

VEICHI AC10

Compact and economical, 0.75 kW to 22 kW

The cost-sensitive choice for straightforward speed control. A narrow book design mounts on rail, on its side or vertically, and an isolated air duct means no derating at 50 C ambient - which matters more in an Indian summer than most spec sheets admit.

Power range

0.75-22 kW

Voltage

1ph 220 V and 3ph 220 V (0.75-2.2 kW); 3ph 380 V (0.75-22 kW)

Control modes

Sensorless V/F; sensorless vector on T3 models

Communication

RS485; plug-in network expansion port

Ambient

No derating at 50 C

VEICHI AC01

Network-type micro drive, 0.4 kW to 7.5 kW

The smallest drive in the range, built for machines where the drive lives inside the equipment rather than a control panel. Book-type structure with hidden wiring, and protection thresholds tuned specifically for small motors rather than inherited from a larger platform.

Power range

0.4-7.5 kW

Voltage

220 V / 380 V

Rated output current

220 V: 3.0-16.0 A / 380 V: 2.5-17.0 A

Communication

Modbus over RS485

I/O

Analog 0-10 V or 0-20 mA; digital inputs; relay and Y-terminal outputs
