IndraDrive Mi: Entirely cabinet-free and modular

Bosch Rexroth IndraDrive Mi

The IndraDrive Mi enables machine manufacturers to integrate all electric drive components directly into the machine. The result: Entirely cabinet free, modular machines with a minimized footprint.

Rexroth is moving the complete drive technology from the cabinet to the machine with decentralized supply and mains modules.

Plant space is valuable. Which is why end-users demand more compact machines in order to increase their production capacities within an existing space. Separate control cabinets take up a lot of space. For this reason, Bosch Rexroth has now developed the technology to make cabinet-free technology a reality. In addition to the company’s proven motor-integrated and near-motor IndraDrive Mi drives, the company has developed decentralized supply and mains modules. Now machine manufacturers can integrate all drive components directly into the machine without the need for a control cabinet. Rexroth designed the cabinet-free supply and mains modules like its motor-integrated and near-motor drive modules with IP65 classification to protect against dust and water stream protection for robust use directly in the machine.

The mains module includes a mains filter, mains regulator and even the mains protection in one device. The energy recovering power supply, control electronics, brake resistor and brake transistors are located in the supply module. The machines and modules are connected to the power supply directly without deviation via the cabinet. This reduces machine assembly wiring by 90 percent.

With the decentralized modules, machine manufacturers can also connect up to 30 IndraDrive Mi units in series in a cable harness up to 200 meters long. Significantly more drives can be switched in series, depending on power consumption, cable length and selected options. In adjacent near-motor drives, a newly developed hybrid plug further reduces assembly work. These protected connector pieces, used for communication and power supply, are simply plugged into an adjacent IndraDrive Mi unit by assembly technicians

Connect to any Control

The IndraDrive Mi offers the following multi -Ethernet protocols: Sercos, PROFINET IO, EtherNet/IP, EtherCAT, and POWERLINK allowing the user to connect to essentially any control.

Increased Modularity

The cabinet-free drive technology extends the possibilities of modularized machine concepts. Machine manufacturers can pre-assemble modules and then connect them to one another at the cabinet without any further work. In addition, Rexroth increases the modularity with standardized interfaces for communication: the IndraDrive Mi supports all of the common Ethernet-based protocols, such as ProfiNet, EtherNet/IP and EtherCAT, and Sercos the automation bus all on one piece of hardware The hardware remains identical and selection occurs purely via software.

To achieve consistent modularization, machine manufacturers are increasingly reallocating control functions to the individual machine modules. With the drive-integrated control unit from Rexroth, drive functions, motion control and motion logic merge into an open automation platform. This IEC 61131-3 standards-based motion logic system controls complex motion tasks. The drive-based control by Rexroth coordinates up to nine IndraDrive Mi units as slaves in real time.

Save energy. Save costs.

The IndraDrive Mi Cabinet-free power supply is a regenerative power supply, returning excess energy to the power grid therefore reducing energy consumption. In Smart Energy Mode it prevents peak loads and greatly reduces average energy consumption. The result of this is better grid compatibility, and the same machine performance with smaller components to reduce cost
