Introduction 

– Salient Features 

Rhino Motion Controls RMCS-3001 is 250W RTU Modbus high performance brushless dc drive. It supports (15

–48V DC) 

and it is designed for optimized operation of Rhino brushless DC motors with Hall sensor. This is an amazing cost effective 
solution to provide closed loop/open loop control for various applications. The salient features of this drive: 
 

 

This drive provides a closed loop/open loop speed control for the brushless dc system. 

 

 

The drive will provide full torque at all speeds within the range. 

 

 

This drive is designed for smooth and quiet operation without compromising on torque and control at higher 
speeds. 

 

 

There is an LED indication for power and error states in this drive. 

 

 

It is possible to run the motor in four different modes. 

 

 

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 RTU protocol through RS485 Communication. 

 

 

There is a function in the drive for setting the Modbus Slave Address from 1 to 247 using MODBUS Tool Device 
(Software Setting). 

 

 

There is an onboard Potentiometer to control speed of motor in Analog control mode. 

 

 

There are five user modes in the drive : 

 

o

 

Mode 0: Analog Open Loop Mode 

o

 

Mode 1: Digital Closed Loop Mode 

o

 

Mode 2: Digital Open Loop  Mode 

o

 

Mode 3: Analog Closed Loop Mode 

o

 

Mode 4: Analog Closed Loop Minimum Speed Control Mode
