Prepare for industry 4.0 with new drive
The IndraDrive Mi servodrive from Bosch Rexroth Corp. breaks free of the control cabinet.
Featuring what the manufacturer calls cabinet-free technology, a novel drive can help users slash the amount of cabling on shop floors and prepare for industry 4.0.
In operations involving machine tools, drives work with motors in the performance of functions, such as part loading and unloading, tool handling, and lifting and lowering spindles. In a conventional setup, however, the drives are located in a control cabinet while the motors are with the machine. Drives and motors are connected to each other via power and communications cables. This means that 50 cables would be needed to connect 25 drives in the control cabinet to their corresponding motors on the machine.
This arrangement changes dramatically when machine tool users opt for the IndraDrive Mi servodrive from Bosch Rexroth Corp., Hoffman Estates, Illinois. Combining the drive and motor, the IndraDrive Mi is located on the machine rather than in a control cabinet. All the drives in a particular setup are connected in series through a single hybrid cable that transmits both power and communications signals.

Integration of the drive and motor into an individual unit greatly reduces the hardware in the control cabinet, according to Bosch Rexroth.
Also, “you don’t have to expend energy cooling off the drives with an air conditioning system,” said Joaquin Ocampo, product manager of motors and drives.
The setup can be cabinet-free with the addition of an IP65 power supply module, which eliminates the need for power supply components in the control cabinet. A cabinet-free arrangement can lower the amount of power and communicationscabling needed for an application by up to 90%, Bosch Rexroth reports.
Besides cabinet-free operation, the IndraDrive Mi features open-core engineering, simplifying communication between the programmable logic controller machine tool environment and PC users.
“OCE allows programmers using C, Java or any other high-level PC language to control or obtain information from our products,” Ocampo said.
