Standard machine “special” use and function in one

AC310 continues the innovative mechanism of the AC300 series, retains the original product features, and it is committed to solving customers’ troubles in selecting models and improving market competitiveness. It has the function of industry expansion, which can be expanded and increased according to the actual use of industry parameters, and integrates multiple industry parameters, so as to realize the “special” use of the standard machine and the integration of functions.

Actively respond to Industry 4.0

With the continuous reform of intelligent production, centralized control of products becomes more common.AC310 products can support different types of DCS systems and PLC systems to achieve commonality, it can also support various types of touch screen and AC310 direct communication, standard MODBUS-RTU communication, compatible and optional support PROFIBUS-DP, CANOPEN, PROFINET communication protocol.


Perfect protection mechanism

It has hardware protection functions such as output short-circuit protection to ground, internal buffer relay protection, fan drive circuit protection, external 24VDC short-circuit protection, motor overload protection, and other hardware protection functions. It can realize all-around protection of the internal and peripheral equipment of the inverter.

Software suppression function:

  • Undervoltage suppression
  • Overvoltage suppression
  • Overcurrent suppression
  • Overexcitation suppression

Unique ingenuity and bringing brilliant control algorithms

  1. Drive a variety of loads: support synchronous, asynchronous, synchronous reluctance motors, electric spindles, AC servos, and other motors.
  2. Comprehensive control modes: one machine covers V/F mode, separation of voltage and frequency, open/closed-loop vector, free choice of speed, and torque.
  3. Motor self-learning: the world’s leading self-learning algorithm, accurate and consistent movement and static.
  4. High-speed field weakening control: high-bandwidth current vector, 12 times the field weakening high-precision output.

New appearance, design and aesthetics are integrated

  1. The book-style narrow body design reduces the volume by up to 60%.
  2. Up and down straight-through heat dissipation, multiple inverters can be installed side by side, greatly reducing the volume of the electrical cabinet.
  3. Brand-new keyboard design, simple appearance, support dual keyboard display.

Make it simple, save more time
