The position of the DC servo motor can be controlled by a STEP/PULSE and DIRECTION digital interface similar to stepper motors. The PULSE/STEP, DIRECTION inputs are optically isolated. Both inputs work with 2.5V, 3.3V or 5V logic drive signals. This drive is fully compatible with Mega torque encoder motors & Rhino IG52 servo encoder motors.


Features

  • Smooth, quiet operation at all speeds and Zero-Backlash DC Servo Motor Performance.
  • Input supply voltage from 12VDc to 48VDC.
  • Selectable Gain Multiplier and Selectable Error Limit.
  • PULSE and DIRECTION inputs with opto-isolated interface.
  • Pots for tuning of Proportional, Integral and Differential Gains and also 1 pot for limiting the current.
  • 2.5V, 3.3V and 5V compatible PULSE and DIRECTION inputs with 2-wire opto-isolated interface.
  • LED indication for power and error states.
