Controls for highest work-piece quality

The user-specific parameters and the start-up data are entered directly on the module or on a separate setting module. With this parameter module setting data can also be entered in another axis. A user-friendly interface monitors operation and reports faults via a 7-segment display and relay output levels. In addition to this single-axis control plug-in unit a simpler variant is also available with a standard interface in the single-axis as well as in the double-axis version. The main spindle and asynchronous motor drives work with a field-oriented control. The closed-loop algorithms are executed on a microprocessor. Parameters provide the basis for specific drive data and start-up settings. Limit comparators signal the operating status to the machine control.

Control plug-in units with high-performance digital setpoint interface for drive bus.

Even higher processing speeds with digital drive controls are standard for productive workpiece processing.

• A digital signal processor ensures high-precision direct control of the axis drive motor per module
• Sophisticated high dynamic control algorithms make workpieces more exact, reduce the down times of the controlled system
• High control quality means the highest precision for your machine
• Precontrols reduce downtimes of the controlled system
• Highest dynamic characteristics can be achieved with linear motors;theoretical speeds up to 300 m/min and accelerations up to 45 g can be achieved werden
• Communication between the SINUMERIK 840D and SIMODRIVE 611 takes place with the drive bus on a real-time synchronous and bidirectional basis with a data rate >30 Mbaud for up to 31 axes
• speed setpoint values and process-dependent precontrols for drives axes
• actual position values prepared in the drive axes from the indirect and direct measuring systems to the machine axes
• four million increments per motor revolution assure highest position quality
• With the digital link the operator panel of the SINUMERIK 840D be used as a start-up and diagnostics tool for drives
• fast start-up using menu assistance
• each optional start-up support in the SINUMERIK 840D accepts the controlled system identification of the feed drive axes and, in addition, independent determination and setting of the speed controller parameterization. A start-up of the feed drives in approximately 5 min./axis can take place with the optional start-up support after preselecting three dynamic categories.
• reproducible settings of the control characteristic qualities, since digital control is not subject to drift and offset influences.
• machine and drive data records of reference machines can be loaded quickly into the standard machine
• "On Board"-Tools erübrigen die teuren Inbetriebnahme- und Servicemeßmittel
• "on-board tools" make expensive start-up and means of service measurement superfluous
• it is possible to "listen in" to the drive from a distance of hundreds or even thousands of kilometers via teleservice
• operating data are displayed directly for the operator on the NC panel
