RoboClaw 2x60AHV, 60VDC Motor Controller (V7C)
The RoboClaw motor controllers from Basicmicro (formerly Ion Motion Control) can control a pair of brushed DC motors using USB serial, TTL serial, RC, or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system. This version can supply a continuous 60 A per channel (120 A peak) and operates up to 60 V. This product is also sometimes referred to as the RoboClaw HV 2x60A.

The RoboClaws from Basicmicro (formerly Ion Motion Control) are a family of efficient, versatile, synchronous regenerative motor controllers. They can supply brushed DC motors with 7.5 A, 15 A, 30 A, 45 A, 60 A, 120 A, or 300 A continuous (depending on the model) at voltages from 6 V to 34 V, 6 V to 60 V, or 10.5 V to 60 V (also depending on the model), and they allow for peak currents well above the maximum continuous ratings. The “Solo” versions feature a single motor control channel while the dual versions (denoted by a “2x” in their names) offer two channels for controlling a pair of motors.

1 Battery Eliminator Circuit
The RoboClaws have a USB interface that acts as a virtual serial (COM) port, allowing it to be controlled directly from a computer, and they feature built-in commands for controlling acceleration, deceleration, distance, speed, current sense, voltage limits and more. Several other interface modes are supported by the RoboClaw as well: it can be controlled via TTL serial for use with embedded systems, RC hobby servo pulses for use as an RC-controlled electronic speed control (ESC), or analog voltages for use with potentiometers or analog joysticks.
RoboClaw automatically supports 3.3V or 5V logic levels, travel limit switches, home switches, emergency stop switches, power supplies, braking systems and contactors. Power supplies can be used by enabling the built in voltage clamping control feature. A built-in switching mode BEC supplies 5VDC at up to 1.2 A or 3 A (depending on controller model) for powering user devices.
The RoboClaws can be operated without feedback for open-loop speed control, or they can be used with a variety of feedback types for closed-loop speed or position control. Quadrature encoders with up to 19.6 million pulses per second are supported and can be auto tuned using Motion Studio, which is a free downloadable application. In addition, a wide range of sensor inputs such as potentiometers and absolute encoders are supported. RoboClaw’s closed loop functionality creates absolute control over speed and direction regardless of load changes.
RoboClaw incorporates several protection features including temperature, current, over voltage and under voltage limits. Several user definable settings such as maximum current limit, maximum and minimum battery voltages are provided for more refined control. The controller uses regenerative braking but can be configured with a voltage clamp circuit to limit the regenerative voltage when used with switching power supplies. The Basicmicro VClamp is a voltage clamp specifically designed to work with the RoboClaw and MCP to suppress such voltage spikes and is rated for use with supplies up to 60 V and currents up to 60 A.

With an operating supply range of 10.5 V to 60 V, the RoboClaw 2x60AHV is a higher-voltage version of the 2x60A (V6), which operates from 6 V to 34 V. The 2x60AHV, which is also sometimes written as HV 2x60A, also has a slightly modified heat sink, which features several tapped holes that can be used for directly mounting a pair of cooling fans. Aside from the sub-millimeter-tall bosses surrounding each tapped hole, the heat sink’s outer dimensions remain the same. This RoboClaw features a USB Micro-B connector that works with our USB micro-B cables.
RoboClaw 2×60AHV, 60VDC Motor Controller (V7B).
This V7B/V7C version is a slightly improved replacement for the 2x60AHV (V6). Specifically, the V7B/V7C has improved MOSFETs and heat sinking for better performance, and the built in 5V regulator (BEC) can now supply to 1.2 A, which is a significant improvement over the 300 mA max for earlier versions. The board size is the same and the locations of the key interface elements (e.g. buttons, terminal blocks, header pins, USB connector, and mounting holes) are unchanged, allowing this version to be used as a direct replacement for the V6 in typical applications.
Key features of the RoboClaw family

Basicmicro has written an Arduino library for the RoboClaw that makes it easy to interface these motor controllers with an Arduino. The library comes with several example sketches that demonstrate different methods of controlling the RoboClaw. They also have an application note that shows how to use their libraries to control a RoboClaw with an A-Star 32U4 programmable controller.
