What communication protocol would you prefer to use in your application?
A-BAR-E Series: Closed-loop motorized electric cylinders with built-in stepper motors, motor encoders, and controllers
To control actuator position, simply transmit on the RS-232 port the unit number of the device you want to move, a simple move command and the position desired. After the move, the actuator will report its position through the RS-232 link.
Zaber's A-Series devices have an indexed knob that provides convenient manual control for versatile operation even without a computer. In velocity mode, turning the knob starts the device moving at a constant speed, and every increment increases or decreases the speed by a configurable amount. In displacement mode, each increment of the knob moves the device by a configurable distance. Pushing in the knob for 5 seconds switches between the modes. You can also issue a stop command by depressing the knob during any operation.
For a detailed list of available commands, see the A-BAR-E User's Manual.
