M-SMC

When synchronous rotary and linear motions are needed, the following question has to be answered: How shall the individual axes be coordinated? The M-SMC software module offers a solution for this task. M-SMC calculates the position and velocity profiles of the drive axles and regulates them. For synchronization of motions the required gear ratios are taken into account and the axes are also accelerated and decelerated during the runtime. This enables an electronic gearbox to be implemented in the shortest possible time. 

• Software module for control, regulation and monitoring of motion axes
• Operation of individual axes or synchronized multi-axis motions
• Jerk-optimized motion profiles
• Several methods for axis synchronization (gearing)
• Configuration and diagnostics via the SolutionCenter
• Commissioning user interface (SMC-Monitor)
• Library for IEC 61131-3 PLC programs

Position synchronization by design 

Production processes often require the position synchronized motion of all drive axes involved. Variable speeds and different roller diameters also increase complexity. M-SMC provides a solution for this task by design. Master-slave relations including the required synchronization method can be defined by means of a configuration. During operation the slave axis can be synchronized at any time and stopped again. This enables application programs such as a flying saw to be implemented in only a few steps. 

Optimized motion profiles 

The approach to a new set position can mostly only be focused on either a minimum travel time or a minimally occurring jerk. The Sin-Lin interpolation function enables M-SMC to offer a solution that combines the benefits of both previous processes. This therefore makes it possible to achieve high production cycles while reducing wear on mechanical components at the same time.

M-SMC also makes it possible to adjust the target position of a motion axis even after it has been started. Therefore no deceleration and restarting is required. In this way, permanently set motion sequences can still be adjusted to workpiece tolerances during the runtime without any loss in production time.

Creating application programs easily 

M-SMC is integrated directly in the higher-level sequence program via the IEC 61131-3 library. This is where set positions are specified, motions are started and axes synchronized if required. Entries made via an HMI are also processed in this program 

The SMC-Monitor commissioning interface enables the full parameterization, operation and diagnosis of the software module. Highly dynamic processes are recorded directly on the controller by the Scope 3 software oscilloscope and fully visualized on the PC. In this way, a complete overview is always ensured. This not only shortens the time required for the initial commissioning, but also enables fast troubleshooting during operation.
