Rexroth speeds up commissioning of drive-based controls

Rexroth expands its modular IndraMotion for metal forming system with the addition of the Sequential Motion Control for drive-based motion logic integration. This means that Rexroth drastically reduces the time required for commissioning and programming of multiple-axis systems. As an alternative to straight PLC programming, Sequential Motion Control speeds up the realization of flying shear systems, feeder applications and gantry systems. The control solution, which is particularly suitable for the forming and general automation market involving up to six axes, offers advantages for modular machine concepts. The certified "Safety on Board" safety functions integrated in the IndraDrive servo-drives satisfy current safety standards and reduce machine downtimes associated with manual intervention.

For the new programming environment, Rexroth has upgraded and simplified the Syntax which is already well known from the 40,000 or so Rexroth CLM systems installed to date. This speeds up commissioning and shortens operator training periods. Sequential Motion Control provides a wide range of functions including jump and motion commands, mathematical tasks, electronic gearing and cam functions, and pre-defined commands for feeder and flying cut-off machines.

In a compiled IEC 61131-3 PLC environment, Rexroth also provides the editor software tool free of charge for use with PC systems. This enables the user to edit, load, debug, start and archive the programs. Comfort functions such as an input assistant and an online help system make it very user-friendly.

Sequential Motion Control provides a manual mode for setting up and referencing the axes, automatic mode for executing the programs and a parameterization mode. The master drive coordinates up to five further drives in hard real time through cross-communication with SERCOS III Ethernet. The multi-tasking system can control up to four tasks in parallel in automatic mode. Moreover, states and diagnoses can be called up at any time by a cyclical task. The user can monitor and adjust variables online. The solution supports fieldbus interfaces such as Profibus and Ethernet protocols for connection to the higher-level machine control system or control level.

Besides the high-performance Motion Syntax, users can also add their own extensions on the basis of an IEC 61131-compliant PLC task in order to meet application requirements quickly and flexibly. Drive solutions equipped with the Sequential Motion Control provide up to 175 inputs and 120 outputs. The certified "Safety on Board" safety functions integrated in the drive react to errors very fast within two msec without the need of a safety PLC. This reduces engineering effort even further and helps machine manufacturers with the further modularization of their machines.
