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. Then click “Save Settings” in the device menu. When operating in bridged channel mode the total peak
current output is combined from both channels. The peak current run time is dependant on heat build up. Adequate cooling
must be maintained. For more information see the RoboClaw user manual.
Bridged Channel Wiring
The RoboClaw 120A, 160A and 400A models are wired the same for bridge channel mode. When bridged channel mode is
active the internal driver scheme for the output stage is modied. The output leads must be wiring correctly or damage will
result. The motor output wire M1B is connected to M2A to form one side. Then M2B is connected to M1A to form the other
side.
