  • Dedicated Energy-Saving Control Technology for both Induction Motors (IM) and Synchronous Motors (SM)
  • Automatic voltage optimization under low-speed or light-load conditions
  • 10%-30% improved energy efficiency compared to standard inverters
  • Synchronous motor driving eliminates rotor copper loss, lowers bearing temperature, and extends motor lifespan
Multi-Pump Intelligent Control
  • Fixed Variable-Speed Pump Mode: 1 variable-speed pump + up to 3 constant-speed pumps (expandable to 11 with optional DO-A3 card)
  • Rotation Switch Mode 1: Cycle variable-speed control for up to 5 pumps (requires DO-A3 card)
  • Rotation Switch Mode 2: Cycle variable-speed control for up to 3 pumps (expandable to 11 with optional DO-A3 card)
Low-Noise Operation & Environmental Adaptability
  • Swing PWM switching technology minimizes electromagnetic interference and operating noise
  • Moisture and dust resistance design compliant with RoHS environmental directives
  • Suitable for harsh environments including outdoor pump rooms and basements
High-Precision Control & Stable Performance
  • High-precision torque limitation (±5% error) under vector control
  • High-speed response above 50Hz with PG feedback control
  • Adjustable acceleration/deceleration time (0.1-3600s)
  • S-curve characteristic switching to prevent water hammer and pipeline vibration
Safety & Long-Life Design
  • Compliant with EN954-1 Cat.3 and IEC/EN61508 SIL2 safety standards
  • EDM (External Device Monitoring) function for real-time safety circuit monitoring
  • 10-year inverter design life with built-in wear part life diagnosis
  • KEB (Kinetic Energy Backup) function for rapid motor shutdown during power outages
Easy Maintenance & Expandability
  • Detachable terminal block with parameter backup function
  • Standard RS-422/485 communication interface
  • Support for PROFIBUS-DP, DeviceNet, CC-Link, and other fieldbuses
  • Compatible with DriveWorksEZ visual programming and DriveWizard Plus debugging tools

Frequently Asked Questions
Q1: Pressure fluctuations during low water demand in European municipal projects?
Adjust Pr.144 (PI Proportional Gain) to 3.0 and Pr.145 (PI Integral Time) to 15.0s. Enable Pr.575 (Sleep/Wake Function) with sleep threshold at 80% of rated pressure. This reduces pressure fluctuation to ±0.1 bar.
Q2: Overheating faults in Southeast Asian sewage treatment plants?
Clean heat sink and fan filter every 2 weeks with compressed air. Install additional axial fan (150m³/h) in electrical cabinet for improved air circulation. Avoid installation near sewage pump to reduce humidity exposure.
Q3: Pressure drop during pump switching in multi-pump systems?
Set Pr.A21 (Multi-Pump Pre-Excitation Time) to 0.5s and Pr.A22 (Pre-Excitation Torque) to 10%. This preloads torque to standby pump before valve opens, reducing switching delay to 0.3 seconds.
Q4: Derating in high-temperature Middle Eastern environments?
Install inverter vertically, add sunshade cover to electrical cabinet, and set Pr.73 (Overload Protection Level) to 120% 60s. For permanent solution, upgrade to -HT high-temperature model (operates up to 55℃).
Q5: Communication issues with Siemens PLC in German chemical plants?
Use optional PROFIBUS-DP/Profinet card (SI-P1). Set Profinet Device Name to match PLC configuration and map pressure data to Process Data Object (PDO). Use shielded CAT5e or higher cable to prevent interference.
Q6: Parameter recovery without damaged terminal block?
Use USB drive with DriveWizard Plus software via front USB port, or use RS-485 cable to copy parameters from another W1000 in same system using Pr.970 (Parameter Copy) function.
Q7: Rust issues in seawater desalination applications?
Upgrade to IP54 high-protection model with corrosion-resistant coating. Temporary solution: apply marine-grade anti-corrosion spray and install dehumidifier in cabinet.
Q8: Overcurrent faults during fire pump startup?
Change control mode to "V/f control" (Pr.79 to 1), increase acceleration time to 5.0s (Pr.71), and enable Pr.250 (Fire Pump Mode). Check for stuck impeller causing high startup load.
