by Vickers
The 916339 board is produced by Vickers and sits within the Vickers Amplifier Boards series. This model functions as an interface that digitizes resolver feedback so a motion controller can read precise shaft position in industrial automation systems. By converting analog resolver signals into discrete count values, it enables closed-loop speed and position regulation on servo axes.
When the board is configured for 10-bit resolution with a 4-pole resolver, each mechanical revolution is divided into 2,048 digital positions; the same 10-bit depth paired with 6 and 8 poles yields 3,072 and 4,096 counts per turn respectively. Selecting 16-bit resolution greatly increases granularity: a 4-pole device produces 131,072 counts per revolution, while a 6-pole element generates 196,608 counts. These higher values improve fine positioning because the controller receives smaller angular increments, lowering interpolation error and enhancing velocity smoothness at slow speeds.
The board provides two feedback sockets in a single connector block rated at DB9 Male x2, allowing simultaneous resolver and auxiliary signal wiring without extra adapters. Its selectable conversion depths—10/12/14/16 Bit—let a commissioning engineer balance update rate against required accuracy. Internally, it processes data from 2 independent resolver channels, so twin transducers on the same shaft can be compared for redundancy or averaged for noise reduction. Mechanical compatibility is broadened because the electronics recognize resolvers wound for 4, 6, 8 pole pairs, eliminating the need for multiple board variants in mixed-motor installations.
