MIV22-3-V5

The part number MIV22-3-V5 from Okuma, a part of the MIV Series, is designed to function as an advanced variable frequency drive. It operates with input voltages between 380V and 480V AC and is capable of producing adjustable output values from 0 to 480V AC. This product manages an impressive output frequency range of 0 to 400 Hz, catering to demanding industrial applications requiring variable speed control for motors.

With a power rating set at 22 kW, this drive efficiently supports tasks requiring robust electrical performance. Its operational current rating is specified at 45 A, facilitating significant power delivery while maintaining optimal energy usage. An overload capability that permits operation at 150% of the rated current for short durations—up to 60 seconds—offers flexibility during peak operational demands.

Control methodologies include vector control and V/f control, empowering this device to fine-tune motor behavior under varying load conditions. Forced air cooling is implemented to ensure consistent thermal management, which is vital in maintaining performance criteria over extended periods. The unit is designed with an IP20 enclosure rating, safeguarding its internal components from relatively low environmental threats typical of indoor settings.

The MIV22-3-V5 functions effectively within a temperature range of -10°C to 50°C during operation and -20°C to 70°C during storage. It also tolerates humidity levels of up to 95% non-condensing, making it suitable for a variety of industrial environments. Communication with this drive is facilitated through Modbus RTU protocol, allowing integration with monitoring and control systems. It is intended for wall mounting, simplifying installation and providing convenient access in operational areas.
