Microstep driver

With CW and CCW limit inputs

Using step and direction signals to operate a motor, the DR-38M intelligent microstep driver offers speed sensed fast/slow decay and ramped jog speed inputs, as well as CW and CCW limit inputs. A 4A, 40V microstep driver, it accepts signals over 28V and works with many PLC controllers. The driver features a RS-232 adapter for customizing configuration memory when removed, or adding input features when attached. Measuring less than 3.25 x 4.25 inches, it has step choices from high torque full step and smooth 1/8 micro step. Step driver may be used in shuttle control applications by converting the step and direction signals to quadrature inputs with an encoder option. Advanced Micro Systemswww.stepcontrol.com Enter 620

Driven by a host microprocessor through an 8-bit or 16-bit bus interface or through an asynchronous bi-directional serial port, the motion processor allows users to offload motion control functions from the applications host. The step motor controller is designed for automation, industrial control, and robotics applications. Performance Motion Deviceswww.pmdcorp.com Enter 626

Linear drive

Mitigates backlash

This linear drive design, intended to eliminate the need for additional drive systems in the company's linear drive units, converts rotary motion input from the drive shaft into linear output with zero backlash. With a control lever on the load-bearing drive unit, users may adjust the angle of contact between the bearing assembly and shaft to allow for changes to travel direction and pitch. No changes to the motor of control settings are necessary to provide automatic reversal of the drivehead, nor are clutches, cams, or gears needed. Amacoil Inc.www.amacoil.com Enter 627
