The SDLWx170 is a step motor “clock and direction” driver implemented through a new generation
DIGITAL SIGNAL PROCESSOR CONTROLLER. In a wall mounting housing the unit
integrates a microstep drive able to move the motor according to CLOCK, DIRECTION, CURRENT
BOOSTING and ENABLE control signals issued by an external master unit through the
5 –:- 24 Vdc driver’s inputs. The drive is also provided with FAULT and BUSY feedback outputs.
All the digital inputs and outputs are optoisolated. Dip-switches are available to user settings. The
unit is powered through one DC or AC bus and can drive the stepper motor in open velocity &
position loops, according to internal or external acceleration and deceleration ramps, while runnig
a real time checking of the critical working parameters as temperature rise, voltages and currents.
