The DB-28104 mounts directly to the DMC-21x3 Ethernet motion controller to perform interpolation of up to four sinusoidal encoders. Compact in size at 3.51 x 3.075 in., the board delivers high position feedback resolution, eliminating the need for ultra high-resolution encoders. The DB-28104 accepts quadrature signals from standard sinusoidal encoders and interpolates the signals to achieve a high resolution. Measuring only 4.25 x 7 in. for one through four-axis models and 4.25 x 10.75 in. for five through eight axes, the DMC-21x3 motion controller is designed for cost-sensitive and space-sensitive applications, come in one through eight axis versions, and can control step or servomotors on any combination of axes. Additionally, this card level controller handles many modes of motion including linear and circular interpolation, contouring, electronic gearing, and ecam. The DMC-21x3 is also available with plug-in, multi-axis amplifier boards that eliminate wiring between the controller and drives.
