| Output Voltage | 0 ~ 400 V AC (or 0 ~ 460 V AC) |
| Rated Current | Approximately 22 A (referenced from the 300 HP model), with the actual value depending on the power rating. |
| Frequency Range | 0 ~ 400 Hz (0 ~ 500 Hz optional) |
| Efficiency | Certified to IEC 61800‑9‑2 standard, with an efficiency of over 96%. |
| Protection Class | IP20 (open-type enclosure) |
| Control Methods | Multiple modes including V/Hz, FORCE vector control, and sensorless vector control. |
| Communication Ports | EtherNet/IP, DeviceNet, Profibus, Modbus, etc. (depending on the optional module selected). |
| Installation Size | Frame 5 (approximately 215 mm × 215 mm × 300 mm) |
| Document Numbers | Installation Instructions: 750‑IN001; Technical Data: 750‑TD100 |
3. Product Features
- High Power Density: Adopts air cooling and an open-type structure, ensuring excellent heat dissipation performance. It is suitable for cabinet installation in space-constrained environments.
- Multiple Control Algorithms: Supports traditional V/Hz, FORCE vector control, and sensorless vector control. This meets the torque and speed requirements of different loads.
- Flexible Input/Output: AC input comes with a pre-charging function, and DC input is also optional. The output can be configured for continuous adjustment within the range of 0-400 Hz (or 0-500 Hz).
- Rich Communication Options: Built-in EtherNet/IP, with optional installation of fieldbuses such as DeviceNet, Profibus, and Modbus. This enables seamless integration with PLCs and upper-level systems.
- Safety and Compliance: Complies with international safety standards including IEC 61800‑9‑2, CE, and UL. It is equipped with built-in safety functions such as safe stop and emergency stop.
4. Structure and Components
- Enclosure: IP20 open-type metal enclosure (NEMA UL Open), which facilitates heat dissipation.
- Internal Modules:Human-Machine Interface (HMI): Optional door-mounted HIM (Human Interface Module) or LCD display. These are used for on-site parameter setting and fault indication.
- Power module (IGBT/transistor array)
- Rectifier/inverter bridge
- Control processor (runs V/Hz and vector control algorithms)
- Filters and capacitor bank
- Terminal blocks (including AC input, DC input, output, and communication terminals)
5. Application Fields
- Manufacturing Industry: Equipment requiring precise speed/torque control, such as conveyors, packaging machinery, presses, and injection molding machines.
- Oil and Gas Industry: Heavy-load drives like pumps, compressors, and fans.
- Food and Beverage Industry: Mixers, filling lines, and cooling systems.
- Mining and Metallurgy Industry: Large fans, hoists, and grinding machines.
- Others: Any industrial automation scenarios that require reliable and programmable motor drives.
6. Installation and Maintenance
Installation
- Follow the mechanical installation guidelines in 750‑IN001 (Installation Instructions). Secure the drive to a cabinet or bracket that meets heat dissipation requirements.
- Complete the power wiring: The AC input must be connected to a pre-charging circuit, and the DC input is optional. Ensure the terminal block labels are clear.
- Connect communication modules (such as EtherNet/IP and DeviceNet). Configure the corresponding drive station in the PLC.
- Perform on-site commissioning: Use RSLogix 5000 (or Studio 5000) to download and verify parameters.
Maintenance
- Regularly check if the heat dissipation channels are blocked, and maintain smooth air circulation.
- Inspect the tightness of terminals to prevent poor contact caused by loosening.
- Conduct annual calibration and functional self-tests in accordance with the recommendations in 750‑TD100 (Technical Data).
- If a fault code appears, refer to the troubleshooting chapter in the user manual. Alternatively, obtain technical support from Rockwell Automation customer service
