Digilent DMC-60
The DMC60C contains four RGB (Red, Green, and Blue) LEDs and one Brake/Coast CAL LED. The four RGB LEDs are located in the corners and are used to indicate status during normal operation, as well as when a fault occurs. The Brake/Coast CAL LED is located in the center of the triangle, which is located at the center of the housing, and is used to indicate the current Brake/Coast setting. When the center LED is off, the device is operating in coast mode. When the center LED is illuminated, the device is operating in brake mode. The Brake/Coast mode can be toggled by pressing down on the center of the triangle, and then releasing the button.
At power-on, the RGB LEDs illuminate Blue, continually getting brighter. This lasts for approximately five seconds. During this time, the motor controller will not respond to an input signal, nor will the output drivers be enabled. After the initial power-on has completed, the device begins normal operation and what gets displayed on the RGB LEDs is a function of the input signal being applied, as well as the current fault state. Assuming that no faults have occurred, the RGB LEDs function as follows:
PWM 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 illuminated Red and Off. |
Neutral Input Pulse Width |
All 4 LEDs illuminated Orange. |
Positive Input Pulse Width |
LEDs blink Green in a clockwise circular pattern (LED1 → LED2 → LED3 → LED4 → LED1). The LED update rate is proportional to the duty cycle of the output and increases with increased duty cycle. At 100% duty cycle, all 4 LEDs are illuminated Green. |
Negative Input Pulse Width |
LEDs blink Red in a counter-clockwise circular pattern (LED1 → LED4 → LED3 → LED2 → LED1). The LED update rate is proportional to the duty cycle of the output and increases with increased duty cycle. At 100% duty cycle, all 4 LEDs are illuminated Red. |

No Input Signal or CAN bus error detected |

All 4 LEDs illuminated solid Orange. |
Valid CAN Control Frame received within the last 100ms. The specified control mode resulted in a Positive Duty Cycle being Motor Output |
LEDs blink Green in a clockwise circular pattern (LED1 → LED2 → LED3 → LED4 → LED1). The LED update rate is proportional to the duty cycle of the output and increases with increased duty cycle. At 100% duty cycle, all 4 LEDs are illuminated Green. |
Valid CAN Control Frame received within the last 100ms. The specified control mode resulted in a Negative Duty Cycle being Motor Output |
LEDs blink Red in a counter-clockwise circular pattern (LED1 → LED4 → LED3 → LED2 → LED1). The LED update rate is proportional to the duty cycle of the output and increases with increased duty cycle. At 100% duty cycle, all 4 LEDs are illuminated Red. |
Fault Color Indicators
When a fault condition is detected, the output duty cycle is reduced to 0% and a fault is signaled. The output then remains disabled for 3 seconds. During this time the onboard LEDs (LED1-4) are used to indicate the fault condition. The fault condition is indicated by toggling between the top (LED1 and LED2) and bottom (LED3 and LED4) LEDs being illuminated Red and off. The color of the bottom LEDs depends on which faults are presently active. The table below describes how the color of the bottom LEDs maps to the presently active faults.
