More often, stepper motors are being replaced by less expensive DC motors. In order to regulate these with high precision, SIGMATEK has developed the CSR 024 module, which has been designed to control DC motors up to a maximum of 85 W.
This highly accurate motor current regulator has been realized in the form of a C-DIAS module, which displays the motor current with an exact resolution. It has three digital inputs and an incremental encoder input with switchable TTL and RS422 levels. For LED lights, two outputs are available with 20 mA and 350 mA respectively; the brightness of which can be regulated. A controlled start-up process ensures smooth starting of the motor and prevents overloading the motor control cards. The CSR 024 current regulating module is ideally suited for backlash-free spindle drives as well as belt and gear drives.
