Overview

The DMC 60 is an electronic speed controller designed for driving brushed DC motors. It utilizes synchronous

rectification to efficiently produce a variable output voltage that’s controlled by a PWM Input Signal. This makes

the DMC 60 ideal for use in robotics applications, including FIRST Robotics Competition.

The DMC 60.

 Sealed, ruggedized, and compact aluminum case

 Tie-wrap and through-bolt mounting – drop-in

replacement for Victor SP controller

 Four multi-color LED indicators sequence to

indicate speed, direction, and status for easier

debugging

 Brake / Coast Calibration button enables one-

touch setting changes and calibration

 Large gauge input/output cables with flexible

silicone insulation

 Integrated thermal sensing and protection –

current-foldback to prevent overheating and

damage

 15.625 kHz output switching frequency ensures

smooth and precise motor control

DMC 60™ Reference Manual The DMC 60’s aluminum case is electrically isolated and may be mounted directly to a robot using zip-ties or #8-32 screws. The case may become hot after pro-longed use in high current applications. For optimum performance it is recommended that the DMC 60 be mounted in a location that allows airflow over the top of the case and around both sides of the case.

DMC 60™ Reference Manual 5 Connecting the PWM Input Signal The DMC 60 continually measures the positive pulse width of the PWM Input Signal applied to the PWM Cable and maps it to an output voltage, or duty cycle. By default, a positive pulse width of 1.0 milliseconds corresponds to 100% duty cycle in the reverse direction (current flow from M- to M+), a positive pulse width of 2.

DMC 60™ Reference Manual what gets displayed on the RGB LEDs will be a function of the input signal being applied, as well as the current fault state. Assuming that no faults have occurred the RGB LEDs will function as follows: Servo Input Signal Applied LED State No Input Signal or Invalid Input Pulse Width Alternate between top (LED1 and LED2) and bottom (LED3 and LED4) LEDs being on and off. When on, the LEDs display color is orange.

If calibration was successful then the top and bottom LEDs will quickly alternate between Green and Off and the new calibration constants will be stored in non-volatile memory. If calibration failed, then the top and bottom LEDs will quickly alternate between Red and Off and the device will continue to operate using the existing calibration constants. Note: Calibration may only be performed while a servo input signal is present.
