YASKAWA A1000 series AC frequency converter

Core advantages of the product

（1） Efficient Energy Saving and Environmental Protection

Quantitative energy-saving effect

Case reference: 100 3.7kW motors are used for HVAC fan systems, operating 365 days a year, with an electricity cost of 0.15 USD/kWh.

Induction motor+ordinary frequency converter: Annual power consumption of 1903100kWh, electricity cost of $285500.

IPM motor+A1000 energy-saving control: Annual power consumption of 1754600kWh, electricity cost of $263200.

Annual electricity savings of $22300, reducing CO2 emissions by 82.4 tons (calculated based on 0.555kg CO2 per 1kWh).

Environmental Design Details

Noise suppression: Swing PWM technology reduces electromagnetic noise and motor operation noise, which is 23.3% lower than previous generation products.

Material compliance: The entire series complies with the RoHS directive, is lead-free and halogen-free, and uses 100% recycled paper and soy ink to print documents.

（2） Safe, reliable, and durable

Security protection system

Functional safety: The Safe Disable function achieves safe shutdown through dual input terminals (H1/H2), complying with EN954-1 Cat.3 and IEC/EN61508 SIL2 standards; EDM (External Device Monitor) function monitors security status in real-time.

Electrical protection: It has comprehensive protection against overcurrent, overvoltage, undervoltage, overload, overheating, grounding faults, etc. When the output current exceeds 200% of the rated overload value, it will immediately shut down.

Environmental adaptation: Provides IP54 dust-proof and drip proof options, supports moisture-proof, dust-proof, oil mist proof, and corrosion-resistant gas design, and is suitable for harsh industrial environments.

Long lifespan and low maintenance

Design lifespan: Key components such as cooling fans, capacitors, relays, IGBTs, etc. have undergone rigorous screening and are designed to have a lifespan of 10 years in an environment of 24 hours, 80% load, and 40 ℃.

Maintenance warning: Built in performance life monitoring function, real-time tracking of cooling fan (LT-1), capacitor (LT-2), surge suppression relay (LT-3), IGBT (LT-4) status, and early output of maintenance signals.

Convenient maintenance: The detachable terminal block supports parameter backup, and there is no need to rewire or set up when replacing the frequency converter; The cooling fan, operator, and other components can be quickly disassembled and replaced.

（3） Convenient operation and flexible configuration

Programming and configuration tools

DriveWorksEZ: a visual programming software that supports drag and drop creation of custom control sequences and detection functions, without the need for complex code writing.

Application Presets: Built in 8 types of application presets for fans, pumps, conveyors, cranes, etc., with one click automatic configuration of core parameters, greatly reducing debugging time.

Operator: Standard LED operator, optional LCD operator (JVOP-180), supports parameter copying and remote operation, equipped with 1m/3m extension cable.

Parameter Management and Migration

Local management: The operator supports parameter copying, and the terminal block has a built-in parameter backup function, ensuring that parameters are not lost after power failure.

Remote management: By using the USB copying unit (JVOP-181) or DriveWizard Plus software, multiple frequency converter parameters can be quickly copied and migrated; Supports RS-422/485 (MEMOBU/Modbus) communication with a maximum baud rate of 115.2kbps.

Flexible installation and layout

Compact design: The 400V 75kW model is 55.4% smaller than the previous generation F7 series, and the 200V 3.7kW synchronous motor is 64% smaller than the induction motor.

Installation method: Supports parallel installation (18.5kW and below), models without heat sinks (upcoming), and external heat sink installation, suitable for different control cabinet space requirements.
