RMCS-3001 RS485 modbus is Rhino Motion Controls introductory Brushless low voltage (15–48 V) DC drive 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 and will survive accidental motor disconnects while powered-up.
The ENABLE, BRAKE and DIRECTION inputs are optically isolated. These inputs work with 2.5V to 5V logic drive signals. Motor will run on application of +ve input supply to ENABLE pins. To facilitate the direction change of Motor shaft, dedicated DIR pin is given. After applying the +ve input supply to DIR pin, power reset is required. BRAKE feature provided for braking the motor rotation.
General Specifications:
- Input Supply Voltage: 15 to 48V
- Rated current : 5A
- Peak Current: 20A
- Smooth and quiet operation at all speeds and extremely low motor heating
- Fully configurable position and velocity loop
- Delivers up to 5A of continuous current
- 2.5V, 3.3V and 5V compatible BRAKE, DIRECTION and ENABLE 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
- Ambient Temperature : 0-70°C
