Stepper motor driver SMD‑8.0DIN

SMD‑8.0DIN is a new-generation stepper motor driver, which provides few control modes and performs excellent dynamics and high torque at high working speeds. The driver is intended to control stepper motors with maximum current per phase up to 8.0 A in bipolar mode. Mounting of the driver on a standard DIN rail makes it easier to place it at the place of production.

The main parameters of stepper motor driver SMD‑8.0DIN

  • Max. current per phase: 8.0 A
  • Power supply: 24 ‑ 48 VDC
  • Microstepping mode: 1, 1/2, 1/4,1/8, 1/16, 1/32, 1/64, 1/128

Additional features:

  • Built-in brake resistor for operation with a high inertia load
  • Possibility to connect external brake resistor
  • Two phase control modes: current control (high torque and better dynamics) or voltage control (silent and very smooth motion)
  • Microstepping up to 1/128
  • Holding current can be adjusted as 70% or 100% of full current value
  • Possibility to invert a signal ENABLE

The operation modes of SMD‑8.0DIN

  • Analog speed control - manual mode - it is used for smooth speed regulation without PC connection. The motor speed is proportional to internal potentiometer regulation. Direction and start/stop are controlled by digital inputs.
  • Pulse position control STEP/DIR - the standard position control mode, motor speed is proportional to a STEP voltage signals frequency, displacement is proportional to a STEP signals quantity. Rotation direction depends on a voltage level at DIR input. Additional ENABLE signal is also provided.

Functions and possibilities of stepper motor driver SMD-8.0DIN:

  • Pulse position control with standard logic low level voltage signals 0…1VDC and high level voltage signals 4…5 VDC (up to 24 VDC on condition that additional current limiting resistances are used) «STEP», «DIR» and «ENABLE» is provided;
  • Analog speed control is provided: using internal potentiometers;
  • The driver is equipped with an internal brake resistor. External brake resistor can be connected as well if needed;
  • Control of a current state of the driver and output of the relevant signal FAULT.
