Compared to the classic 1 Vpp interface, using the MHSSI interface enables direct integration of bearing-free encoder kits into Mitsubishi CNC systems. An additional signal converter box is not required, which saves installation space in the machine and reduces costs for the system. Wiring is greatly simplified and additional connectors as potential error sources are avoided.
Compared to the first generation MiniCODERs, the resolution of the new digital MiniCODERs has been increased 16-fold. This is available up to a maximum speed of 100,000 rpm. When used in high-speed spindles, improved surface quality can be achieved by increasing control accuracy. The integrated signal conversion also allows precise positioning in the scope of a few arcseconds.
In addition to speed and position, the MiniCODERs also record the temperature at the b-side bearing. This makes it possible to monitor the condition of the bearings during warm-up as well as spindle operation under load. The additional transmission of warning and error messages via the digital MHSSI protocol supports Condition Monitoring.
