MTDV series are a compact robust designed motion controller for bipolar stepper motors with winding currents up to 1.2A working at 24V DC. MTDV has a wide product range which allows them to drive from 1 to 4 stepper motors in both open or close loop operations (by means of 1 to 4 encoders) to control different type of motorized optics and motion stages. It features the Ethernet communication interface commonly employed in industrial applications, allowing plug and play operations (USB and RS485 are already implemented at the hardware level and can be developed upon request. Together with a user-friendly Web interface, it is possible to operate the controller with high configurability without installing any software. The controllers are compatible with TCZRS series for changing the magnification and MZMT12X, 12X continuous macro zoom lenses with motorized control. It is also compatible with encoder based XY linear motion stages, which are frequently used for metrology application. MTDV can also be controlled from the customer application using the functions of the provided DLL library. DLL library and code examples can be downloaded from the Opto-Engineering® website. MTDV controller lets you easily set specific F-number, focus and/or zoom settings when used in combination with any compatible lens model (i.e. TCZRS and MZMT12X series) by downloading a specific configuration file from our website containing a lookup table of preset values. Specific configurations can be saved in the controllers non-volatile memory. In order to connect MTDV1CH-22A2 to TCZRS series and to connect MTDV2CH-22A2 to MZMT12X series, a suitable cable indicated in the specification table must be ordered separately. MTDV features a solid aluminum housing and can be easily mounted on a DIN rail for easy integration in any industrial automation environment.
