- Selection Key Points & Notes
- Load Matching Principles
Constant torque loads (conveyors, mixers): select FR-A800 series, rated by ND current
Variable torque loads (fans, pumps): select FR-F800 series, rated by SLD current
Frequent start/stop or heavy starting: select one size larger than motor power
- Special Environment Adaptation
Harsh industrial environments: prefer models with “60” suffix (conformal coating: FR-A840-XXXXX-2-60)
Explosive/flammable environments: select FR-B series explosion-proof inverters
Ethernet communication: select models with “CRN” suffix
- Installation & Maintenance Tips
Vertical mounting, ≥100mm clearance on all sides for ventilation
For long cables, recommend output reactor to reduce dv/dt influence
Regular inspection of cooling fans and capacitors for long-term stable operation
Mitsubishi FR series inverters cover a full power range from 0.1kW to 500kW, meeting diverse needs from basic control to high-precision motion control via differentiated series positioning.
