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 &Â 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.
