STEPPER DRIVER

Features and Benefits:
  • Operates from +12 to 80 VDC
  • Selectable run currents from 0.8 to 10 Amps Peak Holding and Running Torque
  • Step Resolutions from Full step, 2x, 4x, 5x, 8x, 10x, 16x, 25x, 32x, 50x, 64x, 100x, 125x, 128x, 250x, 256x Microstepping
  • Optically isolated inputs that can sink and source (3 to 24 VDC, 16mAmps)
  • Selectable Damping modes for smooth motion
  • Easy to configure without connecting to PC, utilizes DIP switches (Run and hold current, Step resolution, Smoothness setting)
  • Operating temperature of -40C to 85C
  • Operates in ambient temperature of -20C to 50C

 COM (Input)Opto Common input. Used to Optically Isolate the Input when a separate supply is connected. Connecting the +5VDC will make the Inputs Functional but the Inputs will NOT be Isolated. Note COM needs to be powered either by a separate supply or the +5VDC Pin in order for the Input/Outputs to function.Voltage: 3 - 24 VDC
Max Current: 20mA
 DISABLE (Input)Used to Disable drive. Active Low. A closed connection to GND will Disable the drive. This is a Sink or Source InputVoltage: 3 - 24 VDC
Max Current: 20mA
 STEP (Input)The Step output from a Pulse Generator is Input into this pin. Both an NPN and a PNP type PLC can be used for this input. Refer to Connection Diagrams for helpVoltage: 3 - 24 VDC
Max Current: 20mA
 DIR (Input)Used to switch Direction of motor. Active Low. A closed connection to GND will change direction. This is a Sink or Source Input.Voltage: 3 - 24 VDC
Max Current: 20mA
 +5 VDC (Input)Internal +5VDC Output. If Optical Isolation is not desired then it can be connected to COM Pin. DO NOT USE FOR EXTERNAL CIRCUITRY!Voltage: 5 VDC
Max Current: 80mA
