　　The RM6 design concept is based on energy-efficient applications, and the core control technology uses the latest IGBT control technology and digital control system. In addition to providing a user-friendly operating interface, the interface required for a variety of energy-saving applications is simultaneously developed, making it easier to implement energy-saving applications from factory to life. RM6 will be your best choice for saving electricity costs and a few barrels of friendly environment.

1. Provide standard RS-485 communication function and control the inverter through man-machine or PC through Modbus RTU communication interface.
2.Built-in PID control function, can be applied to constant voltage control.Pressure switch start and stop control and pressure abnormality protection function are provided to make constant pressure control more recommended and easy to monitor.
3.With the inverter temperature display, temperature warning and detection, the fan maintenance function can be planned.The inverter over-temperature warning can be set to pre-alarm and notify the maintenance before the fan failure, avoiding the inverter overheating shutdown, reducing the equipment shutdown loss and maintaining the system stability.
4.With inverter fan temperature control start and stop control.The inverter temperature control fan start-stop function can be set to save energy and extend the life of the fan, and extend the fan cleaning and maintenance cycle.
5. The 25KG or higher horsepower model uses an iron cooling fan. The replacement method adopts the upper or front replacement design. The fan has a long service life and is easy to maintain, reducing the burden on maintenance personnel. When the power is off, the fan can run for about 1 minute to remove the waste heat.
6.The frequency converter provides 9 quick monitoring status displays, making it easy for the operator to master the system status.Output frequency, output voltage, output current, heat sink temperature, set pressure, and actual pressure are displayed simultaneously...etc.
7.The inverter is designed to be hot-swappable and can be pulled out to a display distance of up to 100M.The operator wire shares the general computer network cable and 8-pin terminal, which is easy to install and configure.
8.A wide carrier frequency adjustment range of 800~15KHZ can be provided according to different system requirements.The system carrier frequency can be set to 800HZ at the lowest, effectively reducing high-frequency radiation interference, up to 15KHZ, reducing motor noise.
9.With torque motor frequency and torque control.Two sets of analog inputs are provided to control the frequency and torque of the torque motor separately.
10.Provide parameter password lock, set parameter lock and hide parameter setting value, effectively prevent system parameter outflow and human error input. Guarantee the safety of important parameters and enjoy perfect after-sales service.
