MCST 3601 drive electronics for stepper motors

Searching the multitude of available programmable motion controllers for a controller that is ideally suited to miniaturised stepper motors with phase currents of sometimes less than 100 mA was once a real challenge. The MCST 3601 series has now emerged from the cooperation between FAULHABER and Trinamic GmbH, the motion controller specialist for stepper motors. This controller is compact and flexible and, above all, is perfectly suited to the whole range of FAULHABER micro stepper motors.

The series, which is equipped with a microcontroller and a driver, can precisely regulate phase currents from 10 mA to 1.1 A and, at the same time, can be operated with a supply voltage that can vary between 9 and 36 VDC. Thanks to simple and fast communication with a PC via USB 2.0, all types of movements can be programmed using the available software. The ten inputs and outputs also allow external variables to be taken into consideration. Since the controller is designed as a test electronics system, users can adopt the predefined architecture according to their requirements and integrate the components in the platform of their specific industrial application.

Furthermore, the MCST 3601 series can actuate stepper motors in micro stepping mode. In this operating mode, up to 256 micro steps can be programmed per full step. This allows the resolution of the controlled rotary or linear movement to be increased considerably and/or the vibrations caused by the motor to be reduced. This possibility will be welcomed in optics applications in particular as here work is performed at resolutions in the micrometre range.
