The slice type open-loop stepper drive module uses the X-bus bottom bus and is compatible with our company's XB6 series coupler modules. It can directly connect and control two-phase hybrid stepper motors, with built-in positive and negative limit switches, home position, brake input, as well as PP, PV, JOG, HM operating modes. The module has four output channels and seven input channels in total. The output channels support multiplexing for clutch output, device error output, arrival output interface; the seven input channels are respectively for positive limit switch, negative limit switch, home position switch , brake signal and three general inputs. Combined with its inputs/outputs it can meet most of the driving scenarios of stepper motors.
