Modes of Operation
The drive can be configured in the following three modes
1. Mode 0: Analog speed control mode:
a. In this mode the speed of the Rhino DC Servo motor can be controlled by an externally connected
Potentiometer.
b. Speed can be increased or decreased manually based on requirement using potentiometer.
c. The drive will provide full torque at all speeds within the range.
d. However the potentiometer has to be connected via a voltage divider to provide a maximum of 3.3 volts
so as to not damage the drive.
e. Also the Enable, Brake and direction pins have to beconnected as perconfiguration requirements.
2. Mode 1: Digital Speed control mode with direction control:
a. In this mode the speed and direction of the DC servo motor is settable / controllable via a Computer or any
microcontroller board like Arduino or PLC or anyother Modbus ASCII compatible device.
b. Like the analog mode here there is no compromise in the torque output of the motor irrespective of the
operational speed and voltage supply and control at higher speeds.
c. This mode can be used when multiple motors are to be used to run at exactly the same RPM and same
torque even though the voltage supply might be different.
d. Also in this mode the direction of the motor can be controlled digitally via Modbus ASCII commands to run
the dc servo motor in both directions
e. In applications like conveyor belts where speed control is critical and industrial robotic applications like
solar cleaning robots where straight line motion is critical for correction operation of the equipment, the
digital speed control mode can provide optimal results.
3. Mode 2: Position Control Mode:
a. In this mode Speed, Direction, Acceleration and Position of motor can be controlled.
b. The position control mode is suitable in applications where exact movement of motor is required. This
can beused in precision applications like machine control, motion control or robotics.
In all modes absolute encoder position and speed is available on Modbus.
