Distributed servodrives save time and space

21 October, 2013

At the SPS/IPC/Drives show in Germany in November, Siemens will be unveiling a range of integrated servomotors and drives designed to save cabinet space and cabling by being mounted in or on machinery. 

Up to 12 of the Sinamics S120M distributed servodrives can be run from one adapter module, depending on the power required, and any number of adapter modules can be run from an appropriately dimensioned power supply.

Moving the power module out of a cabinet into the motor that drives an axis allows both the volume and the air-conditioning of a cabinet to be reduced. It also reduces the time needed for cabling. The distributed design of the drive also increases flexibility both for new machines and for upgrades. The integrated drive is particularly suitable for modular machine designs, for large machines, or for installations with limited space for the cabinet.

The Sinamics S120M, available in ratings from 0.25–1.5kW, is the distributed version of Siemens’ Sinamics S120 modular drive. A pre-assembled hybrid cable containing all of the signal and power cables reduces the total cable length, as well as cabling times.

Siemens S120M distributed servodrive can cut cabinet costs

The cable connects the distributed drives to an adapter module, which is, in turn, connected to a Sinamics S120 system in the cabinet. Safety functions are available for safe stopping and motion monitoring of the drives.

The distributed design allows parts of plants, or complete plants, to be modularised. Built-in digital inputs and outputs in the drive also enable convenient adaptation to the machine environment in applications such as packaging, printing, glass, and textiles industry.
