Manual -SDC106 –27.10.2014 –v.1.1
2. Driver description
SDC106 is a simple driver designed for dc motors, which provides control of velocity and direction of
motor rotation. Motor velocity is given by an external potentiometer, or by external analog signal
with a range of 0..5 V (given by e.g. PLC driver). Controlling of revolution direction is made by
optically insulated Dir input. Start input determines if motor is rotating or is stopped. To supply driver
you should use non-stabilized feeder, with external power supply equal to rated voltage of
connected motor. Feeder should have a large electrolytic capacitors on output for receiving returning
energy from a driver (BACK EMF). While connecting the driver pay attention to correct polarisation of
power supply, because conversion + with –will cause damage of the driver.
