RMCS-1123 is Rhino Motion Controls new and improved DSP based micro-stepping drive for 1.8deg Bipolar Stepper Motors. It is designed for smooth and quiet operation without compromising on torque and control at higher speeds. It has short-circuit protection for the motor outputs, over-voltage and under-voltage protection.

The RMCS-1123 achieves micro-stepping using a synchronous PWM output drive and high precision current feedback and this is absolutely silent when the motor is stopped or turning slowly. It virtually eliminates stopped-motor heating regardless of power supply voltage using a DSP based PID current control loop.

The RMCS-1123’s closed-loop control gains are calibrated on start-up based on motor characteristics and also adjusted dynamically while the motor is in motion. This control algorithm makes it capable of achieving better torque at higher speeds in comparison to comparable drives in its range.

The PULSE/STEP, DIRECTION and ENABLE inputs are optically isolated. The inputs work with 2.5V, 3.3V or 5V logic drive signals. The input drive current is 5mA at 2.5V so almost all logic family (74LS, 74HC, etc.) can be used to drive these inputs. Each input provides individual anode and cathode connections to the opto-isolator allowing for multiple input drive interfaces.


Micro-Stepping Drive Features

  • Smooth and quiet operation at all speeds and extremely low motor heating

  • Industrial grade performance for 2-Phase Bipolar, 4-Phase and Uni-polar Stepper Motors

  • Input supply voltage from 12VDc to 40VDC

  • Selectable peak coil current from 0.25A to 2A

  • Inaudible 20kHz current chopping frequency

  • Selectable half-current during motor standstill to further reduce motor heating

  • Selectable micro-steps up to 6400 steps per rotation for a 1.8deg stepper motor

  • Higher motor torque and higher speeds achievable due to advanced loop control algorithm

  • 2.5V, 3.3V and 5V compatible PULSE, ENABLE and DIRECTION inputs with 2-wire opto-isolated interface

  • Short-circuit protection for the motor outputs, over-voltage and under-voltage protection

  • LED indication for power and error states

  • This drive is without chassis
