SMC108v2

SMC108-WPv2 is a modern two-phase stepper motor driver developed and produced by WObit based on power stages made in DirectFET ™ technology. This ensured miniaturization of the driver's sizes with quite high control currents characteristic for large and medium-sized stepper motors with a flange size from 110 mm to 57 mm. The compact plastic housing allows the controller to be mounted on a typical DIN rail, and easy access to the switches and signaling diodes allows for quick controller configuration and preview of its operation status.

SMC108-WPv2 is a controller designed to work with a two-phase stepper motor with a bipolar (8- or 4-wire) or 6-wire unipolar winding switched as bipolar. It enables control with full step or step division 1/2, 1/4, 1/8, 1/16, as well as 1/5, 1/10, 2/5, forcing a constant current value in the winding, regardless of the value of the supply voltage. The direction of rotation is controlled using the DIR input. The ENABLE input allows the motor to run or disconnects the current from the motor.

Properties:

  • Power levels with modern DirectFET ™ technology
  • Microprocessor and specialized control system TMC239, equipped with a precise current control and overload control of the upper and lower branches of the power bridge
  • Supply voltage 15..75 DC
  • High rated current - max 7.5A per phase
  • Motor winding current selection: 3… 8 A
  • Step division: 1/1, 1/2, 1/4, 1/5, 2/5, 1/8, 1/10, 1/16
  • 23kHz transistor switching frequency
  • Optoisolated inputs
  • Automatic current reduction
  • Power and control signals on separable strips with screw connections
  • The housing is adapted to be mounted on a DIN rail
  • LED indicators for power / run / error

The driver's power stage is realized by means of miniature MOSFET transistors with modern DirectFET ™ technology. The minimization of losses and high switching efficiency of the power stage allowed for the miniaturization of the size of the controller.

The driver's power stage operates at a switching frequency of 20 kHz, and the mixed method of extinguishing the current results in energy savings with the optimal shape of the current waveform, which is related to the precision of the stepper motor movement (mixed decay). The TMC239 control system includes nonlinear D / A converters that allow to obtain a 1/16 step division, as well as a precise current and overload control system for the upper and lower branches of the power bridge.
