Multi Axis Positioning Motion Controller
The diagram below shows a PMD Magellan MC58000 series or MC55000 series multi-axis motion control IC being
used with two or more Atlas Amplifiers to provide control of brushless DC, DC Brush, or Step Motors in a
positioning application. If desired each axis can control a different motor type, so that, for example, brushless DC
motors can be used along with step motors in the same controller.

Microprocessor-Based Motion Controller
The diagram below shows the Atlas Amplifier being driven by a general purpose microprocessor that provides high
level path generation and servo loop closure and outputs continuous desired torque commands or desired position
increments for step motors to the Atlas Amplifier via the SPI (Serial Peripheral Interface).

Stand Alone Step Motor Amplifier
The diagram below shows the Atlas Amplifier being directly driven by pulse & direction signals. These signals may
come from a microprocessor, a control card, or any other existing motion control device that outputs pulse & direction
signals. In this mode the Atlas unit operates ‘stand-alone,’ and utilizes configuration control parameters previously
stored into the Atlas unit’s NVRAM (non-volatile) memory.
