SMC20 Resolver Feedback Board
The SMC20 resolver feedback board
provides direct interface between the
SMC20 and Vickers motors with 4, 6 or
8 pole resolvers. User selectable
resolutions of 16, 14, 12 and 10 bits are
provided via jumpers (see Table 2-5A).
The SMC20 software automatically
checks the jumper settings. Table 2-5B
shows the maximum RPM and number
of the counts per revolution for each
resolution setting.
