Rhino Motion Controls DC Drive RMCS-2304 with UART ASCII is a high performance dc motor drive (10–30 V DC upto 10A) designed for optimized operation of Rhino DC motors . 

The salient features of this drive:

1. This drive provides a closed loop speed control for the dc system.

2. The motor programmed speeds are maintained irrespective of the voltages supplied.

3. Also by using this drive, the rated torque of the motor is available at all speeds and the torque does not decrease with change in speeds.

4. It is possible to run the motor in three different modes, analog speed control mode,joystick control mode and digital speed control mode.

5. It has short-circuit protection for the motor outputs, over-voltage and under-voltage protection and will survive accidental motor disconnects while powered-up.

6. This drive is configured using MODBUS ASCII protocol via UART.

7. There is a function in the drive for setting the Modbus Slave Address from 1 to 7 using physical jumpers (Hardware Setting) or using MODBUS Tool Device (Software Setting).

8. There are three user modes in the drive :

   1.  Mode0 -  Analog Control Mode

   2.  Mode1 - Joy Stick Control Mode

   3.  Mode2 -  Digital Speed Control Mode

• Input Supply Voltage: 10 to 30V

• Peak Current: 5A

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

• Dimensions : 67mm x 56mm x 13mm

Analog Control Mode:

• In this mode motor can be controlled using an external potentiometer through ADC input.

• In analog mode connect ENA (Pin 4) to GND (Pin 8) to Enable motor.

• Speed of motor can be changed in analog mode by moving an external potentiometer.

Joystick Control Mode:

• In this mode motor can be controlled using a Joystick Module.

• Direction and Speed of motor can be changed moving the joystick forward and backward.

• Motor will stop at Zero position of the joystick.

• In Joystick Mode connect ENA (Pin 4) to GND (Pin 8) to Enable motor.

Digital Control Mode:

• In this mode drive can be controlled digitally through ASCII communication using Modbus Poll.

• Direction/Speed/enable and acceleration of the motor can be change in digital control mode using Modbus poll( similar software can be used)
