WRSTEP SERIES: range of bipolar drivers for the control of low-to-medium power two-phase stepper motors

WIDE-RANGE-Azionamenti-bipolari-per-comando-motori-passo-passo-www.widerange.it

WRSTEP is a range of bipolar drivers for the control of low-to-medium power two-phase stepper motors.

Managed by an 8-bit PIC 16F870 microcontroller, they enable the independent generation of steps in different modes of operation which may be set by means of dip-switches:

  • Each time they are activated they perform a set number of steps before stopping

  • Continuous operation via Enable input

  • Start-stop operation

  • Operation with external clock

The program installed also makes it possible to:

  • Select the operating mode – whole step, half-step, quarter-step, eighth-step

  • Select the nominal current

  • Vary the speed via an internal or external potentiometer or an analogue 0-10 Vcc signal

  • Change the direction through an external signal

  • Activate/Deactivate the acceleration/deceleration ramps

  • Select a range of operation speeds

  • Select the current via a dip-switch

  • Reduce stand-by current automatically when the machine is not operating

All input signals are optically shielded and controllable by open collector logics of the NPN or PNP type, depending on the software installed.

The strong aluminium heatsink allows for perfect heat dissipation and easy assembly.

They are particularly suitable for controlling the movement of unwinders, rewinders and of positioning systems.
