Tříkanálový kontrolér DC motorů DCM 03

DCM 03 is a pre­ci­si­on con­t­roller for an inde­pen­dent con­t­rol of up to three low-power DC motors or actua­tors. The typi­cal appli­cati­on of the devi­ce is posi­ti­o­ning of opti­cal ele­ments (mirrors, len­ses, etc.). A cus­tom-made modi­fi­cati­on of the con­t­roller called “Inter­nal Optics Posi­ti­o­ning Stage” is pre­sen­ted on the pho­to bellow. This pro­duct is used for posi­ti­o­ning of the main opti­cal sys­tem in the inter­acti­on cham­ber in PALS labo­ra­to­ry (Prague’s Aste­rix Laser Sys­tem, CZ).

The DCM 03 con­t­roller allows both stan­dard DC motor con­t­rol (open-loop sys­tems) and a feedback DC motor con­t­rol (clo­se-loop sys­tems throu­gh enco­der sig­nals). The tra­vel limit detecti­on is imple­men­ted too. The posi­ti­on of each motor/actuator is indi­ca­ted on a sepa­ra­ted 8-digit red LED nume­ri­cal dis­play. The con­t­roller can be ope­ra­ted either locally or remo­te­ly via RS-232 serial line. A stan­dard 3U-RACK is used as housing.

Functi­ons: sin­gle step, jog, coun­ter reset, spe­ed con­t­rol, local/remote regi­me.

Note: DCM 03 is a 3-chan­nel modi­fi­cati­on of DCM 08. It allows sequen­tial con­t­rol of up to eight DC motors or actua­tors. All fea­tu­res, functi­ons and para­me­ters are iden­ti­cal with DCM 08.
