Overview

Specifications

Product Features

• Energy Efficiency Optimization: Integrated with Energy Torque Mode, it can automatically adjust motor flux according to load demand. Especially suitable for scenarios where load fluctuates greatly with flow rate, such as fans and pumps, effectively reducing energy consumption.
• High-Precision Control: Supports flux vector control (V/F), voltage/frequency ratio control, and sensorless flux vector control, balancing control precision and response speed.
• Modular Design: Adopts a modular structure, and the drive body, heat dissipation system, and EMC filter can be flexibly configured according to on-site conditions.
• Intelligent Monitoring: Built-in various status indicators (e.g., RED LED indicates abnormal drive voltage), and supports remote monitoring and parameter adjustment through communication interfaces.
• Forcing Functions: Provides forcing functions for equipment such as fans, including forced reverse rotation, forced forward rotation, and forced stop, ensuring the safety of the equipment in case of faults.

Installation & Maintenance

Installation Notes

• Grounding Requirements: Ensure reliable grounding of the chassis, and the grounding resistance should be less than 4Ω to ensure safety and reduce electromagnetic interference.
• Heat Dissipation Requirements: Leave sufficient ventilation space during installation, or install heat dissipation fans or water cooling systems according to load conditions.
• Power Supply Requirements: Please confirm the on-site voltage fluctuation range; the ATV61HD22N4 supports a voltage fluctuation range of ±10%.
• Wiring: Power lines must use shielded cables, and the shield layer must be grounded to avoid electromagnetic interference.

Maintenance & Troubleshooting

• Status Indicators: Observe the status of the indicator lights on the front panel; for example, a steady RED LED may indicate abnormal drive voltage.
• Parameter Reset: After an on-site fault, it is recommended to power off first and perform a parameter reset (Factory Reset) to eliminate possible parameter conflicts.
• Regular Inspection: Regularly check the connection of power lines to ensure there is no looseness or oxidation; check whether the fan is running normally to prevent overheating.
