ATLAS® Digital Amplifiers
ATLAS® Digital Amplifiers are compact single-axis amplifiers that provide high-performance torque control of DC brush, brushless DC, and step motors. They are packaged in a compact solderable module and utilise standard through-hole pins for all connections.
High Performance in an Ultra-Compact Package
ATLAS® Digital Amplifiers are used for direct control of motor torque, or in conjunction with higher-level controllers for velocity or positioning applications. Their very compact size and high-power output make them ideally suited for applications such as laboratory automation, scientific instruments, general-purpose motion control, HVAC, fan & pump controllers, and industrial motor control applications. ATLAS Amplifiers are provided in both vertical and horizontal mounting configurations, and with and without heat sink attachment tabs.
Programmability
ATLAS® digital amplifiers provide many advanced control features including user-programmable gain parameters, performance trace, field-oriented control and I2t current management. Atlas amplifiers are powered from a single supply voltage, providing automatic protection from overcurrent, undervoltage, overvoltage, overtemperature, and short-circuit faults.
Flexibility
The ATLAS® family drives are designed to work seamlessly with PMD’s Magellan family of Motion Processor ICs. As an alternative, 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 & direction
input mode is provided.
