Key Matching and Differences
Table Comparison Items: Mitsubishi FR-D720-0.75K, Lange AD10-0R7G-S2-B-N Matching Conclusion
Rated Power: 0.75kW, 0.75kW, Completely Identical
Input Specifications: Single-phase 200–240V AC, 50/60Hz; Single-phase 220V AC, 50/60Hz; Voltage range compatible, can be directly connected
Output Specifications: Three-phase 200–240V AC, 4.2A; Three-phase 220V AC, 4.0A; Current slightly lower, sufficient load margin
Overload Capacity: 150%/60s; 200%/0.5s; 150%/60s; 200%/3s; AD10: Stronger and more stable short-term overload
Control Method: V/F, Flux Vector Control; High-performance vector control (supports asynchronous/permanent magnet); Control performance no less than the original unit
Built-in Functions Features include PID control, torque boost, stall prevention, built-in PID control, braking unit, speed tracking, and more. It offers comprehensive functionality, with the addition of a braking unit.
Protection/Size: IP20, approximately 1kg; IP20, approximately 1.5kg. Installation space compatible; slight weight increase is acceptable.
Replacement Recommendations:
Wiring can be directly reused: Single-phase 220V input connects to L and N terminals; three-phase output connects to U/V/W, no modification required.
Quick parameter adaptation: Restores motor parameter self-learning; overload level set to 150%/60s; carrier frequency as per original operating conditions (1–16kHz adjustable).
Functional supplement: The AD10 has a built-in braking unit; if the original unit has an external braking resistor, it can be directly used without additional cost.
Communication and Panel: Both have local operation panels. If communication is required, ensure the MODBUS address and baud rate are consistent beforehand.
Applicable Scenarios and Precautions: Suitable for light to medium load scenarios such as fans, water pumps, and small conveyor lines; it can completely replace the original unit.
If the original machine has special process parameters (such as specific torque increase, multi-speed), it needs to be readjusted after replacement to match the load characteristics.

VI. Safety and operation tips ⚠️ Installation, wiring, and debugging must be performed with the power off. Improper operation while the power is on carries the risk of electric shock and equipment burnout.
For first-time use, it is recommended to perform motor parameter self-learning to ensure vector control accuracy.
For long-term operation, ensure proper ventilation and heat dissipation of the cabinet, avoiding dusty and humid environments.
In case of overload, overcurrent, or overheating faults, the inverter’s ALM alarm light will illuminate, requiring shutdown and investigation of load and environmental issues.
