asynchronousPWMthree-phase

Overview
The AC600F from Veichi Electric is a vector-control universal AC drive designed for operation in harsh environments (dust, high humidity, heavy rain). Power range: 0.75–22 kW. Compact, high power density and ready for immediate operation after wiring.

Key Features

• IP66 industrial sealing and UV-resistant PC housing for outdoor exposure and corrosive atmospheres.
• Fast heat dissipation and low noise via built-in smart fan and independent air duct.
• Dual-layer safety: optional mechanical disconnect and STO (Safe Torque Off) meeting SIL3.
• Strong EMI suppression: standard C3 filter, optional higher-grade C2 for strict environments.
• Global approvals (CE, UL, CB) and wide-voltage input design allowing ±15% fluctuation.
• Wide motor compatibility: supports synchronous, asynchronous, reluctance and other motor types.
• Module programming and external bilingual keypad (Chinese/English) for flexible control.

Advantages

• High starting torque and smooth low-speed control: closed-loop vector mode delivers up to 200% rated torque at 0 Hz; torque linearity <3%.
• Over-excitation braking for rapid braking without additional resistors and suppression of DC bus overvoltage during deceleration.
• Energy-saving control with auto excitation current adjustment according to load to maximize motor efficiency.
• Stable high-speed flux-weakening control with precise output at high multiples.

Hardware Structure

• Ultra-low-noise IP66 cooling fan designed for quiet operation.
• Fiberglass + high-strength polycarbonate enclosure for strength, light weight and corrosion resistance.
• Internal circulation cooling with intelligent temperature control and modular design for effective heat exchange.
• Common-mode choke + film capacitor noise filtering using phase cancellation and common-mode differentiation for EMI suppression while preserving signals.
• Comprehensive protections from input to output; automotive-grade cooling solutions for improved dissipation.

Software Configuration

• Multi-motor control: supports 3-phase asynchronous, variable-frequency, AC servo, PM synchronous, synchronous reluctance and high-speed synchronous motors.
• Black box function: automatic fault recording and data tracking for troubleshooting and analysis.
• PC tools: parameter configuration, oscilloscope display, multi-device management and torque tuning for commissioning and monitoring.
• Robust connector and logic: multi-device parameter arithmetic/logic, secondary channel settings, up to 10 function blocks with 3 inputs each.
• Multi-motor parameter switching: stores 4 motor parameter sets for quick motor changes without hardware swaps.
• Built-in application macros: tension control, power balancing, dual-PG positioning, independent dual PID, firefighting mode, etc.
• Motor auto-tuning upgrade: online parameter correction for accurate adaptation to varied motor specifications.

Extension Configuration

• High expandability with multiple expansion interfaces; up to three expansion cards simultaneously.
• Fieldbus support available: PROFIBUS, PROFINET, EtherCAT, Ethernet/IP and major protocols.

Applications

• Food processing: blowers, centrifuges, separators, mixers, grinders — precise process control, energy savings, STO (SIL3) and bilingual keypad for simplified operation.
• Military, marine, submarines: conveyors and critical systems — designed for salt spray, condensation, vibration and temporary immersion; optional C2 filter and +24V external power for communications during main power loss.
• Urban water pumps / outdoor fans / rail: compressors, pumps, outdoor HVAC — energy efficiency, adjustable ramping and reliable long-term operation.
• Metallurgy, mining, heavy industry: fans and pumps — dust-tight, corrosion-resistant construction to prevent contamination-induced failures; IP66 up to 22 kW (IP55 up to 90 kW available).
