Machine Door Actuator

Protective Machine Door Actuator for Horizontal Doors

Thanks to functionality based on many years of experience, machine door actuators from SERVAX offer application-specific software and the latest generation of drive elements for the ideal solution both technically and economically. The basis for the new generation is the tried and proven TÜV certified (EN-13849-1 PLd) technology for personal access.

Key advantages at a glance:

  • Fast opening and closing times
  • Compact, space saving and maintenance free
  • Direct drive configurable with intelligent operating software

Typical areas of application:

  • Machine tools (lathing, milling, grinding etc.)
  • Die casting machines
  • General production machines

Overview

Safely Automate Horizontal Machine Doors

The use of automatic door drives in modern machines has increased in recent years. The trend towards automating every possible machine function also includes opening and closing the doors of protective machine hoods. Loading and unloading machines represents a particular source of danger for both the operating personnel and expensive loading robots.

These protective machine door actuators include the technology for implementing a safe force and speed limit for horizontal doors with door weights up to 750 kg and more. This enables safe compliance with the approved forces without requiring additional safety elements such as light barriers or two-handed operation. The drive is fitted with a protective function which triggers an immediate change of direction to prevent irreversible damage if an obstacle is encountered.

The intelligent operating software – SMDTuner – assures efficient commissioning of the drive. Thanks to the integrated AutoTuning, there is virtually no need to perform settings during commissioning.  The system is powered by 115/230VAC, features galvanically isolated 24VDC I/O, and has an opto-isolated interface to the machine PLC.  The SMDA drives continue to offer valuable support for implementing safe and reliable automated protective doors.

Software

Quick and Easy Operation Software

SMDTuner

With the user-friendly SMDTuner operating software, commissioning the protective door the first time is quick and easy. This PC program is used to parametrise the machine door actuator, start up the machine door actuator, query status values, and save the data so that data records already created can be archived for documentation purposes.

The software is easy to use and requires no special training. A wizard guides you through the submenus in just a few steps. The software lets you individually optimise all JANUS drive types for various door configurations. This reduces costs during commissioning and maintenance.
