Pneumatic Scale was the first company in the U.S. to develop a rotary servo capper, using ELAU’s purpose-built PacDrive SCL technology, a self-contained servo module that eliminates the need for separate power amplifiers and electrical cabinets on the rotating turret.

In its Three-in-One packer, Goodman Packaging Equipment is the first to use PacDrive iSH Series Intelligent Servo Modules from Elau.

Unlike a conventional servo motor and drive, this self-contained servo module receives all power and communications from its own hybrid cable coming from a nearby distribution module.

No separate encoder cables are needed, and each module is fully synchronized through a digital motion bus running in its single hybrid cable. A central, shared power supply feeds these remotely located distribution modules.

The net result is reduced complexity and installed cost, says Goodman. Instead of a cabinet filled with servo drives and cable connections, only a single PacDrive automation controller and power supply are located in the electrical cabinet.

The servos and their distribution modules are installed around the machine, right at the point of use. And because they are IP-65 rated, they’re fully capable of routine washdown.
