FRECON Electric (Shenzhen) Co., Ltd.
FRECON Electric began in Shenzhen in 2013 and works across industrial automation, energy conversion and renewable-energy products. Its FR500A/FR510A catalogue distinguishes ordinary speed control from feedback and positioning functions. Published process examples cover vacuum pumping and coordinated conveyor motors, while its PV and off-grid ranges follow different input and application requirements.

The Shenzhen company and a specific research-centre record.
Company history and a government publication provide different pieces of the identity record.
Industrial automation and energy conversion
The current company profile names FRECON Electric (Shenzhen) Co., Ltd. and dates the business to 2013. It describes inverters, servo drives, energy-saving control cabinets and solar-inverter systems among its development areas. The published contact is in Huidongsheng Industrial Park, Guangming, Shenzhen. For a purchaser, the industrial FR-drive offer and a solar-energy system are two distinct technical scopes within that broader business.[1][2]
Recognition with a date and named supporting company
Guangdong’s 27 January 2026 notice recognizes the 2025 engineering research-centre cohort. Entry 232 of its attachment names 孚瑞肯电气（深圳）有限公司 as the supporting company for the Guangdong Green Energy Conversion and Intelligent Drive Engineering Technology Research Center. This is a specific external record of research context. It concerns the company and centre; acceptance of an individual drive still follows its model-specific engineering and conformity documents.[4]
Choose the control requirement before choosing the suffix.
V1.8 presents FR510A as an extension of FR500A, with named additional capabilities.
FR500A: speed-control foundation
The catalogue describes FR500A for OEM machinery and fan/pump applications, with sensorless vector and V/F control. It names speed tracking for a rotating motor, oscillation suppression and application macros. The drive can therefore form part of a process-speed or material-handling task. The proposed control mode, motor data and startup conditions need to match that machine, especially in a retrofit where the motor may already be rotating when control resumes.[3]
FR510A: feedback and positioning additions
The FR510A description adds synchronous-motor support, multiple PG-card options, two motor-parameter groups and position functions including spindle orientation and pulse following. The encoder section separately names several feedback types. A spindle or positioning enquiry should identify the actual encoder and card combination as well as the drive. These functions belong to the FR510A route rather than being silently added to every FR500A specification.[3]
The catalogue identifies the power platform, air path and braking choices.
These are product-design details that help define a cabinet and parts list.
Electronics and cooling arrangement
V1.8 describes an IGBT-based hardware platform and an independent cooling-air duct, with cooling fans forming part of the thermal arrangement. It lists output-to-ground short-circuit, fan-circuit, external 24 V and motor-overload protection functions. Optional PT100/PT1000 motor-temperature protection is separately identified. For a machine running in dust or heat, retain the exact protection option and installation arrangement rather than treating the product’s general protection list as the complete cabinet specification.[3]
Built-in braking is tied to the model range
The braking illustration distinguishes the FR500A configuration up to and including 37 kW from the 45–75 kW range, where a built-in braking unit is optional. The nameplate explanation also identifies the B suffix for a built-in unit. This makes the full order code and braking assembly useful quotation details. A motor’s deceleration cycle and regenerated energy need to be assessed with the selected hardware, not just the family’s nominal power range.[3]
A conveyor example separates motor speed from load sharing.
The 2 June 2026 manufacturer article describes two 380 V, 160 kW motor-driven conveyors and the control relationship between them.
FR500A and the dedicated FR500AB
The example’s requirement is balanced output and load distribution between two motors. It describes one general FR500A and one dedicated FR500AB. The dedicated device reads the other drive’s speed and current over RS485 and adjusts its operating speed. The article also discusses a master in speed mode and a follower whose mode can be selected for the application. This is a supplier-described arrangement, with the named dedicated variant retained in the profile.[6]
Commissioning a coupled load
The article connects the arrangement with synchronized motion, current balancing and controlled acceleration/deceleration. For a similar conveyor, the motor list, mechanical coupling, starting load and load-sharing acceptance criteria should be agreed together. The communication map and accepted master/follower parameters are useful commissioning deliverables. A single combined kW figure would conceal how the individual drives exchange information and share the mechanical task.[6]
Vacuum pumping begins with process feedback and operating demand.
FRECON’s 11 May 2026 article provides an application discussion for a two-stage vacuum system.
The feedback path is part of the retrofit
The article describes motor-speed regulation in a two-stage pumping system and outlines a vacuum sensor, PLC/control system and FR500A feedback path. That gives an engineering team a starting point for the control architecture. The pump’s permitted speed range, process vacuum requirement, sensor scaling and start/stop sequence remain project-specific inputs. The profile uses that control description without presenting the article’s numerical performance claims as measured platform results.[5]
PID functions identified in V1.8
The catalogue describes two PID parameter groups and selectable reference/feedback sources, with feedback-loss detection and sleep/wake functions. Those are useful capabilities when preparing a process-pump offer. The proposed configuration should identify which PID function is used, where the process signal comes from and how a failed signal changes operation. Commissioning acceptance can then test the intended process behaviour alongside ordinary motor operation.[3]
PV pumping and off-grid power conversion are separate routes.
The current product navigation distinguishes FR industrial drives, PV pump products and SP off-grid inverters.
PV150A/500 and PV580
The portfolio lists PV150A/500 as solar-pump products and PV580 as an IP65 solar-pump drive. A photovoltaic pumping brief needs the array’s electrical characteristics, pump motor and water demand, alongside installation conditions. That is a different input-source discussion from an AC-fed FR500A process pump. Retaining the PV family name prevents industrial and solar-pump features being merged into one unspecified inverter.[2]
SP off-grid products
SP-series off-grid inverters appear as a separate category in the same navigation. An off-grid power-conversion product and a variable-speed motor drive have different output tasks. A purchaser should state whether the project needs a controlled pump motor or an off-grid electrical supply, then obtain the matching product documentation and system components. The portfolio makes that distinction available before a quotation is prepared.[2]
Keep the expansion hardware and parameter backup with the offer.
A useful parts list connects the proposed control behaviour to the delivered accessories.
Networks, feedback and commissioning files
V1.8 lists communication expansion cards and identifies parameter upload/download equipment and background commissioning software. For an FR510A feedback application, retain the encoder and PG-card details; for a conveyor, retain the dedicated follower variant and exchange signals. The accepted parameter set, applicable catalogue/manual revision and commissioning records should describe that same configuration. This gives maintenance staff a practical reference when replacing hardware or restoring settings.[3][6]

Buyer questions
What does FR510A add in the V1.8 catalogue?
The catalogue adds synchronous-motor support, PG-card options, two motor-parameter groups and positioning functions such as spindle orientation and pulse following.
Which devices appear in the coal-washing conveyor example?
The supplier’s article describes a general FR500A and a dedicated FR500AB, with the latter reading speed and current over RS485 to coordinate the two motors.
Is the research-centre recognition a certification for every drive?
The Guangdong notice names the company supporting the engineering research centre. Individual product conformity and technical acceptance use the supplied model’s documents.
Can I use one enquiry brief for a PV pump and an industrial FR pump?
Both need motor and process requirements, but a PV system also needs array/input information. The catalogue separates those product routes.
