- キー交換の注意事項
3.1 負荷タイプのマッチング
Confirm the original load is constant torque (the design target of ATV71); for variable torque loads (ファン/ウォーターポンプ), it is recommended to use the ATV610 series for higher efficiency.
For heavy-duty applications (例えば, hoisting), ATV930 or heavy-duty inverters of other brands must be selected to ensure 150% torque output capacity.
3.2 Key Parameter Migration Points
主要パラメータ: 加減速時間, torque limit, PID parameters, motor nameplate data (must be re-entered).
Communication settings: Modbus address, baud rate and data format must be consistent with the original system.
Safety functions: STO parameters need to be reconfigured to meet the safety class requirements of the original system (ISO 13849 PL e).
3.3 ハードウェアの互換性
設置寸法: ATV340 is slightly smaller and ATV930 is slightly larger than ATV71; confirm the installation space is compatible.
端子配置: The terminal positions of the new series have changed, requiring rewiring.
Accessory Adaptation: Original ATV71 I/O expansion cards and communication cards cannot be directly used for ATV340/930 and need to be replaced with corresponding models.
3.4 Utilization of Function Upgrades
ATV340/930 are equipped with a standard encoder interface (optional for ATV71), enabling higher precision control.
The new series supports industrial Ethernet such as EtherNet/IP, facilitating system upgrade to Industry 4.0.
Enhanced diagnostic functions can early warn of faults and reduce downtime.
- Recommended Replacement Implementation Steps
4.1 Preparations
Record all parameters of the original ATV71 (backup with Schneider SoMove software is recommended).
Confirm motor nameplate data (力, 電圧, 現在, スピード, 極番号).
Evaluate load characteristics (constant torque/variable torque, starting torque requirements, braking needs).
4.2 Selection Confirmation
Select ATV340 or ATV930 series according to the application scenario.
Confirm accessory requirements (communication expansion card, brake resistor, フィルター, 等).
4.3 インストール & 試運転
Install the new inverter with power off and ensure correct wiring (pay special attention to phase sequence).
Enter motor parameters and perform auto-tuning (mandatory step).
Migrate key control parameters and test basic operation.
Verify communication connection and safety functions.
Conduct load test and adjust parameters to the optimal state.
