Eaton has announced the M-Max series of sensorless vector adjustable frequency drives.
Users can program the microprocessor-based drives to tailor their performance for use with conveyor belts, transport drives, packaging machines, pumps and fans.
The M-Max product line uses a 32-bit microprocessor and insulated gate bipolar transistors. The standard drive includes a digital display and operating and programming keys.
The display provides drive monitoring, as well as adjustment and diagnostic information.
The keys are used for digital adjustment and programming of the drive, as well as for operator control.
Separate terminal blocks for control and power wiring are provided for customer connections.
The drives have a start-up wizard, condensed parameter list and a parameter upload and download tool.
They also feature RS-485/Modbus, standard proportional-integral controller and several fieldbus options, as well as include conformal coated boards, 50°C ratings and a temperature controlled fan.
The M-Max also supports the connection of external 24 volt control power to maintain control and communication in the case of a main power loss.
