Emerson unidrive M300 is ideal for applications that require cost effective integration into safety systems and advanced RFC-A open-loop motor control. M300 drive provides an upgrade path for Commander SK users who want a similar feature set with the addition of integrated dual STO inputs to provide SIL3/PLe conformity and enhanced RFC-A open-loop motor control. M300 frequency inverter has an easy-to-use fixed LED keypad as standard and a useful parameter guide on the front of the drive to enhance understanding when setting up and interrogating. Parameter sets can be easily saved or transferred between drives using the Unidrive M Connect PC tool or an SD card with AI-Back-up adaptor.
- M300 has integrated dual STO inputs for SIL3, PLe conformity, eliminating the need for external safety components
- Rotor Flux Control (RFC-A) gives maximum stability and control of induction motors at all powers.
- 180% motor overload suitable for heavy industrial machinery applications
- M300’s SI interface enables integration with a wide range of available industry standard fieldbuses and I/O
- Simple fixed LED keypad
- Useful parameter guide located on the front of the drive
- Use Unidrive M Connect or an SD card with the AI-Backup adaptor to clone and transfer parameter sets
- DIN rail mounting is supported below 1.5 kW
