Amplifiers
There are a few options for configuring Atlas units for stand alone operation:
• Pro-Motion can be used with the Atlas Developer’s Kit to program Atlas units
• The user can develop their own NVRAM programming system by utilizing the SPI (Serial Peripheral
Interface) Atlas command protocol. For more information refer to the
Atlas® Digital Amplifier
Complete Technical Reference
.
• PMD offers custom pre-configured Atlas units. For more information contact your local PMD sales
representative.

Force Control
The Brushless DC and DC Servo Atlas units can be used for general purpose force control applications such as remote
teleoperation, force feedback, solonoid actuation, and any other general purpose valve/actuator control where a
precisely controllable current is needed.
In this application the torque command may be sent continuously by the host microprocessor or from time to time as
required by the application. In either case the Atlas provides very accurate current/torque control resulting in smooth
and precise application of force.
