Installation & Selection Guidelines
IP20 rating: for cabinet mounting only, not for outdoor exposure.
No built-in EMC filter. An external EMC filter must be added if EMI compliance is required on site.
Integrated braking IGBT. External braking resistor is mandatory for high-inertia or fast-stop applications.
Heavy duty operation: rated current remains 10.5A continuous, 150% overload for 60 seconds.
Alternatives & Replacement Options
Same series & power rating: 25B-D010N114 (version with built-in EMC filter)
Domestic alternatives: Inovance MD290, Invt GD270 and other 4kW 380V AC drives with Ethernet. Note: Communication protocols differ and program modification is required.

- Alarm F11: STO safety circuit open; safety terminals not shorted or safety circuit fault.
- F04 Overcurrent: Motor short circuit, damaged cable or shorted braking resistor.
- F08 Overtemperature: Poor cabinet heat dissipation, dust clogged heat sink.

✅ Selection Checklist (Suitable / Not Recommended Scenarios)
Suitable Applications
- Projects using Rockwell PLC requiring native EtherNet/IP fieldbus communication
- Machinery safety standards requiring STO safe torque off
- 4kW motor with heavy-duty demand (150% overload for 60s)
- OEM packaged machinery with compact cabinet space
Not Recommended Applications
- High voltage, corrosive environment or outdoor installation without enclosure (IP20, cabinet mounting only)
- Projects without EtherNet/IP and STO safety requirements (Cost-effective PowerFlex523 is optional)
- Very high inertia, frequent emergency stop with insufficient cabinet space for braking resistor installation (Braking transistor only works with external resistor)
