RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Control Interface (CTRL) RoboClaw 120A, 160A and 200A use Molex style female connectors. The following tables list the pins and their available functions. All pins are 5V tolerant and output 3.3V for compatibility with processor such as Rasberry Pi and Arduino. CTRL1 and CTRL2 pins are low side drivers at 40VDC, 3A per output. R/C pulse input, Analog and TTL can be generated from any microcontroller such as a Arduino or Rasberry Pi.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Encoders (ENC) RoboClaw supports dual quadrature encoders with up to 9.8 million pulses per second. In addition, a wide range of sensor inputs including potentiometers and absolute encoders are supported. The encoder pins are not exclusive to supporting encoders and have several functions available. The encoder inputs were isolated on a separate connector for wiring convenience.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Digital Driver (DRV) RoboClaw includes two general purpose 40V at 3Amp output I/O for controlling brakes, contactors and inductive devices. The DRV pins in combination with a simple circuit can be used to regulate the regenerative function of RoboClaw allowing use of DC power supplies. The DRV pin functions are defined using Motion Studio. They can also be setup using packet serial commands. See RoboClaw User Manual for examples.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Motor and Battery Terminals Data Sheet RoboClaw utlizes screw terminals for both motor channels and main battery connections. The screw teminals are secured with a M5 screw and nut. The screw and nut are easily replacable if necessairy. The recommend ring termials can be purchased from Digi-Key A112030-ND and can support up to 6AWG wire.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Logic Battery (LB IN) The logic circuit of RoboClaw can be powered from a secondary battery wired to LB IN. A logic battery will prevent brownouts when the main battery is low or under heavy load. The positive (+) terminal is located at the board edge and ground (-) is the inside pin closest to the heatsink. Encoder Power (+ / -) The pins labeled + and - are the source power pins for encoders.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Main Battery Screw Terminals The main power input can be from 6VDC to 34VDC on a standard RoboClaw and 10.5VDC to 60VDC or 80VDC on an HV (High Voltage) RoboClaw. The connections are marked + and - on the main screw terminal. The plus (+) symbol marks the positive terminal and the negative (-) marks the negative terminal. The main battery wires should be as short as possible. ! Do not reverse main battery wires or damage will occur.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Control Modes RoboClaw has 4 main functional control modes explained below. Each mode has several configuration options. The modes can be configured using Motion Studio or the built-in buttons. Refer to the RoboClaw User Manual for installation and setup instructions. RC Using RC mode RoboClaw can be controlled from any hobby RC radio system. RC input mode also allows low powered microcontrollers such as a Basic Stamp to control RoboClaw.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Wiring Safety In all system with movement, safety is a concern. This concern is amplified when dealing with higher voltages. The wiring diagram below illustrates a properly wired system. An external main power cut off is required (SW1). The external cut off can consist of a high amperage mechanical switch or a contactor.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Contactors, Relays and Solenoids As a safety precaution a contactor, relay or solenoid with the proper ratings for the planned load should be used (RY1). The disconnect devices contacts should be rated for the total current output of both motor channels combined. The disconnect device can be controlled by the DOUT pins or a simple manual switch. The DOUT pins are designed to control inductive loads.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Logic Battery An optional logic battery is supported. Under heavy loads the main power can suffer voltage drops, causing potential logic brown outs which may result in uncontrolled behavior. A separate power source for the motor controllers logic circuit, will remedy potential problems from main power voltage drops. The logic battery maximum input voltage is 34VDC with a minimum input voltage of 6VDC.
