Maximum motion dynamics with the JetMove 400 series
08 April 2009
The JetMove 400, the latest drive family of Jetter in Ludwigsburg, was designed for highly precise axis movements and also for very dynamic applications.
These drives are used in particular when both precision and dynamics are required at the same time. Together with a fast Ethernet real time bus they guarantee high-precision coupling of several axes.
The JetMove 400 runs with a controller cycle of 100 kHz. This results in maximum path accuracy of the drives. External interference is compensated for directly and mechanical vibration is actively damped. Additional complex control algorithms to compensate for interference are no longer necessary. The result is a high level of precision and dynamics combined with a robust drive.
In order to enable controlling in the 100 kHz range, the corresponding signals such as the current value or position value are processed with an even higher cycle. The signals are evaluated by a FPGA. This enables a degree of speed and accuracy which is unknown in conventional servo-drives. Axes limited by running noises become much smoother and can be controlled at a higher speed and rigidity. On the other hand, stationary precision is also a decisive criterion for controllers.
Up to 32 axes can be coupled to the Ethernet realtime bus. With a synchronisation cycle of 10 kHz and a maximum jitter of less than 100 ns, axes involved in a co-ordinated motion synchronise with one another extremely quickly and precisely.
Axes with a controller from the JetMove 400 series are used, for example, in the following applications: Machine tools, printing machines, pick-and-place robots, medical technology, laser machining, high-precision test and measuring instruments and also in highly dynamic applications from the semiconductor sector, such as wire bonders or wafer handling machines.
