A Proven Platform Continues to Evolve

VEIKONG is pleased to introduce VFD500Plus, the next evolution of the proven VFD500 high-performance vector drive platform. For many years, VFD500 has served customers across a wide range of industrial applications and has built a strong reputation for stable operation, practical functions and reliable motor control. It has been one of VEIKONG's important general-purpose drive products and a dependable choice for machine builders, system integrators and end users.

VFD500Plus builds on that established foundation. The “Plus” designation represents continuity as well as progress: the new series retains the practical general-purpose positioning of VFD500 while expanding motor compatibility, control performance, functional safety, communication options and system scalability. It is designed for customers who value the proven strengths of VFD500 but need additional capabilities for newer machines and more connected industrial systems.For users and service teams already familiar with VFD500, this development path also creates a clear product logic. Existing VFD500 experience remains valuable, while VFD500Plus provides a higher-specification option when new projects introduce more demanding motion control, safety integration or network requirements. Customers can therefore select the appropriate platform according to actual application needs rather than treating every project as requiring the same drive configuration.

Broader Motor Compatibility

VFD500 has provided mature control for asynchronous motor applications in many industries. VFD500Plus extends this capability to a wider range of motor technologies. In addition to asynchronous motors, it supports surface-mounted permanent magnet synchronous motors, interior permanent magnet synchronous motors and synchronous reluctance motors.

This broader compatibility allows equipment manufacturers to use one drive platform across more machine designs. Whether a project focuses on traditional induction motors, higher-efficiency permanent magnet motors or newer synchronous reluctance solutions, VFD500Plus provides greater flexibility for product development, upgrading and standardization.

Enhanced Vector Control and Low Speed Performance

Building on the V/F and sensorless vector control experience of VFD500, VFD500Plus provides V/F control, sensorless vector control and closed-loop vector control with a speed sensor. Its speed regulation range reaches 1:100 under V/F control, 1:200 under sensorless vector control and 1:1000 under closed-loop vector control.

The drive also delivers strong low-speed load capability: 150% at 0.5 Hz in V/F mode, 180% at 0.25 Hz in sensorless vector mode and 180% at zero speed in closed-loop vector mode. These improvements give users more control headroom in applications requiring stable starting, accurate speed regulation, rapid load response or dependable torque at very low speed.

A Wider Power Range and Stronger System Scalability

VFD500Plus covers power ratings from 0.4 kW to 1000 kW, allowing the same product family to support compact machinery as well as large industrial systems. The expanded range helps customers reduce the need to combine unrelated drive platforms when equipment portfolios include both low-power and high-power machines.

Two motor parameter groups, multiple acceleration and deceleration settings, process PID, simple PLC logic, multi-step speed operation, skip frequency and V/F separation further improve adaptability. These functions support different operating conditions without losing the straightforward commissioning approach expected from a general-purpose drive.

Functional Safety and Reliability Upgrades

Dual Safe Torque Off inputs are standard on VFD500Plus. In an appropriately designed safety system, STO can prevent the drive from producing motor torque and gives machine designers a more convenient basis for integrating functional safety. The final safety architecture should always be evaluated according to the machine, risk assessment and applicable standards.

Reliability has also been further strengthened through thermal simulation, optimized heat dissipation and an independent air duct that helps reduce dust entry into the drive. A large-air-volume, long-life cooling fan and enlarged aluminum heat-sink fins support temperature control. Comprehensive protection functions cover conditions including phase loss, overcurrent, motor overload, drive overload, overtemperature, ground short circuit, motor overspeed, speed deviation and PID feedback loss.

More Communication and Expansion Choices

VFD500Plus retains standard Modbus communication and adds a broader range of optional network solutions, including CANopen, EtherCAT, PROFINET, Modbus TCP, Ethernet and BACnet. This makes the drive easier to integrate into PLC systems, industrial Ethernet networks, building automation and more advanced machine architectures.

Encoder expansion options include incremental encoders, resolvers and Tamagawa-protocol absolute encoders. Users can also select a standard digital keypad, an optional dual-display keypad or an optional LCD keypad. Together with expandable I/O and communication options, these choices make configuration more flexible while keeping the standard product practical.

Smooth Operation for Modern Industrial Applications

Speed tracking start allows VFD500Plus to identify and smoothly restart a motor that is still rotating, helping reduce current and mechanical shock on fans, pumps and other inertia loads. Over-excitation can assist deceleration in suitable applications, while under-voltage stall prevention helps the motor decelerate in a controlled manner during a momentary power interruption and supports recovery after power returns.

VFD500 remains a proven high-performance platform whose reliability has been demonstrated through years of industrial use. VFD500Plus carries that experience forward and adds more capability for projects that require multiple motor types, higher control accuracy, functional safety, broader connectivity or a larger power range. With this launch, VEIKONG offers customers a stronger and more future-ready general-purpose drive platform without losing the practical engineering foundation that made VFD500 successful.
