Variable Frequency Drive
FD500 Distributed Inverter
An IP65 drive that mounts beside the motor instead of in a central cabinet, cutting motor cable runs and the EMI that comes with them.

is an innovative device different from traditional centralized inverters. It allows inverters to be distributed and installed near motors, and works in coordination through the communication network between the control unit and the power unit. Technologies such as pulse width modulation (PWM) are adopted to precisely regulate the motor speed and power. It features high-precision speed regulation, fast dynamic response and high reliability. With advantages including significant energy conservation, reduced electromagnetic interference, and convenient installation and maintenance, it is widely used in various fields such as industrial automation, power systems, and transportation. It can effectively improve the operating efficiency of the system, and reduce energy consumption and maintenance costs

Problems it solves
Why this model gets specified
Long motor cables from a central cabinet radiate EMI and cost copper. Distributed installation next to the motor shortens the run.
Central drive cabinets need floor space and cooling. FD500 is rated IP65 and lives on the machine.
Distributed topologies still need one control view. Control and power units coordinate over the network, with ModbusRTU, CanLink, PROFINET, PROFIBUS-DP and ASI available.
Who it is for: Conveyor, material-handling and process OEMs moving from centralised drive cabinets to decentralised installation.

Engineering detail
Technical features
- FD500 is an inverter designed to be mounted on motors and is compatible with 90% of motors available on the market
- Compact Size & Flexible Installation The distributed inverter adopts a modular design, with a volume 30%-50% smaller than traditional electrical control cabinets. It can be directly installed at the equipment site, reducing cable length and lowering wiring costs
- Rich peripheral interfaces to meet various application scenarios
- Reduced Equipment Integration Costs No separate electrical control cabinet is required, which cuts down on equipment investment. It is particularly suitable for scenarios with strict space requirements such as logistics and automotive industries
- Lower Operation & Maintenance Costs The modular design facilitates maintenance and component replacement, and a single fault will not affect the operation of other equipment
- Precise Control & Energy Efficiency Optimization By independently adjusting motor speed and frequency, it avoids energy waste of traditional equipment and can save 10%-20% of energy
- High Power Factor & Reduced Harmonics It adopts multi-level PWM control, resulting in an output voltage waveform close to a sine wave. The power factor is as high as 0.9 or above, and input harmonics are reduced by more than 80%
- Dynamic Response Capability Independent control of each piece of equipment enables quick adaptation to load changes, improving the overall efficiency of the system
- Decentralized Architecture It does not rely on a single power source, and a single-point fault will not affect the operation of other equipment, enhancing system reliability
- Strong Scalability The modular design supports flexible expansion and can be adapted to industrial scenarios of different scales and complexities. Technical Specifications
Before you order the FD500 Distributed Inverter
Four or five details decide the model code. These are the ones that matter for this series:
- Confirm the supply and rating
- Voltage Level: 220V±15% / 380V±15%
- Confirm the supply and rating
- Power Range: 220V 0.75-1.5KW / 380V 0.75-5.5KW
Every Boray unit is full-load tested before delivery, and the customised VFD programme can adapt function set, protection rating and mechanical arrangement where a standard model does not fit. Operation manuals and wiring diagrams are issued per model code — request them with your enquiry.
