RDIM16, Resolver-to-digital Interface

The RDIM is a plug-in module that can be connected via the standard MC-BUS, a motion control connector, to all Technosoft Development Tools. It provides excitation to the resolver and translates the returned angular analog information into a digital form, for motion control applications using motors with resolver feedback. The digital angular position output information is available on the MC-BUS in two forms:

• As a serial binary output, providing the absolute position. This output is available on the serial peripheral interface (SPI) pins of the MC-BUS;
• As 2 quadrature signals, A and B, and the Z (zero) pulse, emulating an incremental encoder. These signals are available on the quadrature encoder interface pins of the MC-BUS; The encoder-emulated outputs continuously produce signals equivalent to a 1024-line encoder. If these outputs are used with an encoder interface, this multiplies the resolution by 4, providing 4096 pulses per rotation.

Main Features:

• 12-bit serial absolute position
• 4 x 1024-line incremental encoder emulation
• Differential inputs for resolver signals
• Internal 7-kHz oscillator providing sinusoidal excitation up to 7.5 VRMS, 40 mA
• Short-circuit protection
• Standard MC-BUS connectors allowing direct connection to the MSK2xxx boards
• Internal step-up supply
• Powered via the MC-BUS connector
