Stepper Motor Power Stage MCD+ - PHYTRON - #1

Text version of the page

CONTROL The MCD+ is a bipolar power stage for driving 2 phase stepper motors. All operation parameters - phase currents, step resolution and preferential motor direction - are programmable by rotary switches or in the ServiceBus mode. The MCD+ is designed for power supplies from 24 to 70 VDC. The control pulse, motor direction, boost, activation and reset inputs are compatible with push-pull or open collector signals. The control inputs are electrically insulated from the supply and motor voltage. A special feature of the MCD+ offers 3 terminals for each signal input. Thus separate input terminals for 5 V and 24 V are available. Application The MCD+ is suitable for up to 450 Watts of shaft power that is ideal for controlling spindle and toothed belt drive systems for mechanical handling or assembly applications. The high step resolution makes the MCD+ the best solution for applications that have especially high demands on precision, smoothness and durability. MCD+ Compact Stepper Motor Power Stage with ServiceBus Rotary switch mode The run and the stop current can be changed between two ranges by the current range switch. These phase currents can be set in 15 increments up to 9 APEAK. In this operating mode the step resolution can be adjusted from full step up to 1/20 step. ServiceBus mode All settings are entered at the PC, which is easy to do with the free phytron software ServiceBus-Comm® for Windows®. In the ServiceBus mode the phase currents can be programmed in 100 mA increments, the step resolution from full step to 1/512 step and the current delay time from 1 to 1000 ms. ServiceBus-Comm® Highlights Compact design The complete device plus wall mounting brackets measures only 127 x 38 x 110 mm.
