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 19.6 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 - IONMC.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Digital Driver (DRV) RoboClaw includes two general purpose 40V at 3Amp output for controlling brakes, contactors and other high load 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 can be defined using Ion Studio. They can also be setup using packet serial commands. See RoboClaw User Manual for examples.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Logic Battery (LB+) The logic circuit of RoboClaw can be powered from a secondary battery wired to LB+. A logic battery will prevent brownouts when the main battery is low or under heavy load. The positive (+) terminal is labeled LB+ and ground (-) is shared. The minimum input voltage is 6VDC and the maximum is 14VDC. ! Failure to remove LB-MB jumper when a logic battery is in use, will result in damage.
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 Ion 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 Basics RoboClaw must be wired correctly to ensure safe and reliable operation. The wiring diagram below illustrates one of several possible wiring configurations. An external main power cut off solution should be incorporated for safety. Regeneration will occur if the motors are moved when the system is off causing possible erratic behavior.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Logic Battery An optional logic battery supply 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 circuits, can remedy potential problems from main power voltage drops. The logic battery maximum input voltage is 12VDC with a minimum input voltage of 6VDC.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Contactors, Relays and Solenoids As a safety precaution an external power disconnect device should be used. A disconnect such as a contactor, relay or solenoid with the proper ratings for the planned load. 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.
RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet Bridging Channels RoboClaws dual channels can be bridge to run as one channel, effectively doubling its current capability for one motor. Damage will result if RoboClaw is not set to bridged channel mode before wiring. Download and install Ion Studio. Connect the motor controller to the computer using an available USB port. Run Ion Studio and in general settings check the option to combine channels.
