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:
-
This drive provides a closed loop speed control for the dc system.
-
The motor programmed speeds are maintained irrespective of the voltages supplied.
-
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.
-
It is possible to run the motor in three different modes, analog speed control mode,joystick control mode and digital speed control mode.
-
It has short-circuit protection for the motor outputs, over-voltage and under-voltage protection and will survive accidental motor disconnects while powered-up.
-
This drive is configured using MODBUS ASCII protocol via UART.
-
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).
-
There are three user modes in the drive :
-
Mode0 - Analog Control Mode
-
Mode1 - Joy Stick Control Mode
-
Mode2 - Digital Speed Control Mode
General Specifications:
-
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)
