Product Features
- High Power and High Torque: With a rated power of 185 kW and a starting torque of up to 200% of the rated value, it meets the requirements of heavy-duty starting.
- Multiple Control Modes: Supports PID, V/f, vector control, and sensorless vector control, enabling flexible adaptation to different processes.
- Rich I/O and Communication: Equipped with multiple analog/digital input and output interfaces, and compatible with RS‑485/422, facilitating fieldbus integration.
- Reliable Heat Dissipation and Maintenance: Adopts a replaceable fan design and is equipped with preventive maintenance monitoring to reduce the risk of downtime.
- Modular Structure: Features a detachable I/O terminal board and an independent control PCB, allowing for easy on-site replacement and upgrading.
- Safety and Diagnostics: Built-in functional safety, overload, overcurrent, overvoltage, and other protection functions, along with a diagnostic panel for on-site viewing.
Structure and Composition
- Main Chassis: Houses the power module, control PCB, and cooling fan.
- Control PCB (A1000 Series): Responsible for calculation, parameter storage, and communication interfaces.
- I/O Terminal Board: Provides access for analog/digital signals and supports on-site wiring.
- Power Supply Module: Internal auxiliary power supply for the control circuit.
- Heat Dissipation System: High-efficiency fan + heat sink, replaceable on-site.
- Brake Unit (Optional): Used for loads that require quick stopping.
Typical Application Areas
- Pump stations (centrifugal pumps, positive displacement pumps)
- Fans and blowers
- Conveying systems (belt, chain drive)
- Hoisting and lifting equipment (winches, elevators)
- Compressors
- Mixing and stirring equipment
- Traction drives (rail transit, mining vehicles)
Installation Points
- Foundation and Fixing: Ensure the chassis is installed on a solid, level foundation to avoid vibration.
- Electrical Wiring: Comply with IEC/GB standards, use compliant cables and junction boxes, and pay attention to the phase sequence of the three-phase power supply.
- Heat Dissipation Channels: Keep the fan inlet and outlet unobstructed; use forced ventilation if necessary.
- Grounding: Properly ground the chassis and control board to prevent electromagnetic interference.
- Parameter Setting: After the first power-on, set motor parameters, control mode, acceleration/deceleration time, etc., via the LCD/keypad or upper-level software.
- Safety Protection: If on-site protection is required, additional enclosures or protective doors can be installed to prevent misoperation.
Maintenance Recommendations
- Regular Fan Inspection: Clean dust and replace the fan if necessary to ensure heat dissipation.
- I/O and Communication Monitoring: Check the integrity of signal line connections and confirm the normal operation of RS‑485/422 communication.
- Parameter Backup: Back up key parameters using internal storage or external media to prevent accidental loss.
- Fault Diagnosis: Use the LCD/keypad or upper-level software to read fault codes and replace faulty modules (such as IGBT, control PCB) in a timely manner.
- Preventive Maintenance: Inspect and replace key components such as capacitors and filters in accordance with the manufacturer’s recommended operation schedule.
