GA700 Series High-Performance Multifunctional Frequency Converter
The GA700 inverter series builds upon Yaskawa's legacy of high-quality drives, designed around the core principles of "Versatility", "Ease of Use", and "Reliability". Featuring advanced motor control for enhanced efficiency and integrated peripheral devices to reduce system costs, it delivers practical solutions with excellent global environmental adaptability.
Core Features & Advantages
Control Performance
Open/closed-loop vector control compatible with IM/PM/SynRM motors; high torque without PG (±5% torque accuracy); max output frequency up to 590Hz for stable operation and fast response.
Energy Efficiency & System Cost
Automatic energy-saving mode with integrated DC reactor, brake transistor, and EMC filter to reduce harmonics and minimize peripheral components.
Ease of Use & Maintenance
Guided startup, multi-language keypad, parameter backup/replication with DriveWizard Mobile/Desktop support for fast commissioning and reduced downtime.
Safety & Compliance
STO (SIL CL3, PLe, Cat.3) safety function with 24V auxiliary power supply for communication maintenance and life prediction monitoring.
Environmental Adaptability
Operating temperature: -10～60℃ (no derating at 50℃); coated PCB; optional vibration resistance; multi-protocol communication for global deployment.
Industry-Specific Functions
Specialized features for winding/wire drawing including tension control, roll diameter calculation, taper adjustment, and thread breakage detection.
Control Modes: V/f, Open-loop/Closed-loop Vector; supports IM/PM/SynRM motors; sensorless high-torque startup; max output frequency 590Hz
Integrated Components: Built-in DC reactor (30kW ND and above), brake transistor (≤90kW ND), EMC filter (common C3 class)
Safety: STO (SIL CL3, PLe, Cat.3) as standard for safety-critical applications
Environment: Operating temperature -10～60℃ (no derating at 50℃); optional coated PCB and vibration resistance
Communication: Standard Modbus RTU; optional EtherNet/IP, Profinet, EtherCAT for system integration
Application Fields
General Industrial Manufacturing
Medium & small machine tool factories, electronics factories, automotive parts factories leveraging high-precision vector control, wide temperature range, and multi-motor synchronization capabilities.
HVAC & Water Treatment
Commercial buildings, municipal water treatment plants, data centers with automatic energy-saving mode, voltage fluctuation tolerance, and constant pressure control.
Material Handling & Logistics
Ports/warehouses, e-commerce sorting centers, mines with sensorless vector control, multi-protocol compatibility, and dust/moisture resistance.
Textile & Printing
Textile factories, printing plants, non-woven fabric production with tension control, roll diameter calculation, and high-precision speed synchronization.
Food & Beverage
Dairy factories, beverage filling plants, canning factories with optional IP65 stainless steel enclosures, rapid start/stop, and wide voltage adaptation.
Common Questions & Solutions
Q: The GA700 triggers EMC warnings during testing. What's wrong?
A: Check if your model has the "BBA" suffix (built-in EMC filter). Ensure proper wiring separation between power and control cables (≥10cm apart) and verify adequate ground wire thickness and connection.
Q: Inverter shuts down with "OV" (overvoltage) error in areas with voltage fluctuations.
A: Adjust "Voltage Fluctuation Tolerance" to 15% in parameters. For frequent deceleration applications, use built-in brake transistor with external brake resistor to dissipate regenerative voltage.
Q: Can GA700 work with existing Profinet systems?
A: Yes, select "Profinet option" when ordering. Ensure PLC baud rate matches (100Mbps) and enable "Profinet Communication" in parameter Pn001 during commissioning.
Q: Keypad malfunctions in humid environments.
A: Replace standard keypad with optional IP54 waterproof keypad or install inverter in sealed electrical cabinet with dehumidifier.
Q: Energy savings potential for fan systems?
A: Automatic energy-saving mode adjusts motor speed according to air pressure, typically saving 25-40% energy compared to power-frequency operation.
