The motor itself is capable of providing position measurements using its TMCS-28 incremental encoder and hall sensors. Nonetheless, a wire position sensor was included to complement the motor’s measurement in an absolute way. 3. Control system design Regarding the control system shown in Fig. 5, and its electronic circuit in particular, the central part of the system is the motor driver, a brushless motor driver also from Trinamic, the TMCM-1630, powered by a 24V power supply.

It also includes a few safety features, such as an emergency button and a power relay. The latter is controlled by a custom endstop controller, which is constantly monitoring a PC status output and the endstops that were mounted in the moving beam’s path . A change in any of these inputs would then disconnect the power supply from the driver,
