Product Details
General Purpose AC Drive VFD – Universal Electrical Motor Control
Industrial-grade variable frequency drive for robust electrical motor control — engineered by HANI to deliver precision, energy savings, and field-proven reliability.
Modern industrial automation demands a drive that seamlessly integrates into any motion system while providing superior electrical motor control. The General Purpose VFD series (also known as AC Drive or Variable Frequency Drive) from HANI redefines what a universal drive can achieve. Whether you operate centrifugal pumps, conveyors, extruders, or high-speed spindles, this drive delivers adaptive torque regulation, regenerative energy management, and real-time responsiveness. With over 15 years of field data across cement, textile, and HVAC industries, the platform combines an X86 hardware backbone with a deterministic real-time operating system — a rare combination that ensures both raw computational muscle and microsecond-level task scheduling for demanding electrical motor control loops.
⚙️ True industrial computing core: X86 CPU + Real-Time OS
Unlike conventional ARM-based drives that struggle with complex algorithms, HANI’s Variable Frequency Drive integrates a powerful X86 processor running a preemptive real-time multitasking operating system. This architecture delivers cycle times as low as 250µs for speed control loops and supports concurrent execution of up to 16 custom tasks. The result? Jitter-free torque response, high order dynamic decoupling, and seamless management of multi-drive synchronization — essential for high-performance electrical motor control in printing presses or winders. Floating-point intensive calculations for sensorless vector control are executed natively, improving low-speed torque by 35% compared to standard fixed-point DSPs.
🎛️ Comprehensive control modes for every application
Out of the box, the General Purpose VFD provides three standard control architectures: V/F control (for multi-motor or fan/pump applications), advanced sensorless vector control (SVC), and closed-loop flux vector control with encoder feedback. Additionally, a dedicated torque control mode enables wind/unwind applications where tension regulation is mandatory. All modes are optimized for induction motors, permanent magnet synchronous motors (PMSM), and synchronous reluctance motors. Below is a technical summary:
| Control mode | Speed accuracy | Torque response time | Ideal use case |
|---|---|---|---|
| V/F (Voltage/Frequency) | ±2% (basic) | > 20 ms | Fans, pumps, group motor drives, simple conveyors |
| Sensorless vector control | ±0.5% (30:1 speed range) | < 5 ms | Centrifuges, extruders, hoists (encoderless) |
| Closed-loop vector (with encoder) | ±0.01% | < 2 ms | Precision positioning, test benches, elevators |
| Torque control mode | N/A (torque accuracy ±3%) | < 1 ms | Winding/unwinding, tension rollers, load sharing |
Every mode benefits from adaptive dead-time compensation, automatic motor parameter identification, and anti-resonance filtering. This makes the AC Drive an optimal choice for retrofitting existing electromechanical systems where electrical motor control precision directly impacts product quality. Support for high carrier frequencies (up to 16 kHz) reduces audible noise, perfect for hospital or office building ventilation applications.
🌐 Rich industrial networking and open software architecture
The drive comes standard with Profibus DP-V1 and Powerlink (real-time Ethernet) interfaces, eliminating extra gateway costs. Optional plug-in modules further extend connectivity to PROFINET, EtherCAT, Modbus TCP, CANopen, and DeviceNet. What truly sets this General Purpose VFD apart is the software standardization: all internal parameters, control words, and status words strictly adhere to CiA 402 / PROFIdrive profiles. The register mapping for Variable Frequency Drive communication matches major PLC brands, reducing engineering hours by up to 40%. HANI’s engineering team has integrated a free-programming function (IEC 61131-3 compliant, with ladder diagram and structured text) inside the drive. Users can develop custom logic — from dynamic braking sequencing to pre-warning algorithms — without external controllers. This open approach transforms a standard AC Drive into an application-specific intelligent node.
📌 Real-world benefit: One packaging machine integrator reduced logic complexity by merging filling station timing control inside the drive, saving a dedicated PLC. The built-in free programming executes cyclic every 2 ms, and can access all drive signals (DC-bus voltage, output current, I/O status) — ideal for condition monitoring and predictive maintenance.
🖤 Inbuilt “Black Box” fault recording – 2 seconds of transparent data
Unexpected downtime is the enemy of productivity. Unlike conventional logging that only stores fault codes, the integrated Black Box recorder continuously captures real-time operational data (speed reference, actual speed, DC bus, output current, torque, temperature) at a high sampling rate (1 kHz). Upon any fault trip, the drive automatically saves a time-stamped file containing 2 seconds before and after the fault event. Users can export this data via the front USB port or remote connectivity, and then reconstruct the exact electromechanical sequence using any oscilloscope tool or HANI’s analysis software. For mission-critical electrical motor control systems, this black box turns a cryptic trip into a fixable root cause analysis. Example: intermittent overcurrent caused by load spikes from upstream machinery — the file shows voltage sag and torque oscillation 300ms before trip, leading to corrective parameter tuning.
🔐 Remote diagnostics & VPN-powered support (your data secured)
For global production lines, instant expert help reduces mean time to repair (MTTR). With explicit customer authorization, HANI’s support engineers can establish a secure VPN tunnel to the on-site maintenance server, and then directly connect to any running Variable Frequency Drive on the network. The remote tool allows real-time monitoring of all parameters, temporary firmware upgrades, oscilloscope-like tracing, and even parameter restoration. No travel costs, no delays. This remote diagnosis function fully respects cybersecurity best practices: two factor authentication, session logging, and granular user rights. Over the last 24 months, this feature reduced average support resolution time from 32 hours to 4.5 hours across 270+ industrial sites.

Beyond specs, what truly accelerates custom machine design is the drive’s open software environment. HANI provides a full parameter editor and development kit based on CODESYS runtime. The control word, status word, and scaling parameters follow the electrical motor control standards laid out by ODVA and PROFIBUS International. As a result, any General Purpose VFD can be dropped into existing PROFIBUS or Powerlink networks without rewriting the master configuration — indispensable for system integrators. The free programming block also allows dynamic PID parameter adjustment (gain scheduling), custom logic for emergency stop patterns, and torque-limited jogging.
🏭 Industrial applications – where this AC Drive excels
