Performance Motion Devices ATLAS® Digital Amplifiers provide high-performance torque control for DC brush, brushless DC, and step motors. They are packaged in a compact, solderable module and are ideal for use in positioning motion control, velocity control, and precision force control applications. ATLAS Digital Amplifiers are used for direct control of motor torque, or in conjunction with higher-level motion controllers. Their very compact size and high power output make them ideally suited for applications such as medical equipment, laboratory automation, scientific instruments, general-purpose motion control, force feedback, and actuator controls. ATLAS Amplifiers are provided in vertical and horizontal mounting configurations, with three power levels, and two package sizes.
ATLAS Digital Amplifiers utilize proprietary digital current control and switching technology for exceptional efficiency and quiet motor operation. Control features include user-programmable gain parameters, performance trace, field oriented control, and I2t current management. ATLAS amplifiers are internally powered from a single motor supply voltage, and provide automatic protection from overcurrent, undervoltage, overvoltage, overtemperature, and short circuit faults.
The ATLAS family has been designed to work seamlessly with Magellan Motion Control ICs. Alternatively, they can be used with dedicated FPGAs, digital signal processors, or general-purpose microprocessors. Communication is via SPI (Serial Peripheral Interface) using a simple, packet-oriented protocol. For step motors, in addition to the SPI format, a pulse and direction input mode is provided.
