-The DMC60C's response when a neutral duty cycle is applied to the output depends on the Brake / Coast setting. When the DMC60C is configured for Brake Mode, the M+ and M- leads are internally shorted when a neutral duty cycle is applied to the output, which causes an attached motor to resist rotation. If an attached motor is spinning, then its speed decreases at a much quicker rate than it would if the M+ and M- leads were allowed to float. When configured for Coast Mode, the M+ and M- leads float when a neutral duty cycle is applied to the output.+The DMC60C's response when a neutral duty cycle is applied to the output depends on the Brake/Coast setting.

-The current Brake / Coast setting is displayed by the Brake / CAL LED, which is in the center of the triangle located at the center of the housing. When the device is operating in Brake Mode, the LED is illuminated Red. When the device is operating in Coast Mode, the LED is off. The Brake / Coast setting can be toggled by pressing down on the center of the triangle, then releasing the button.+The current Brake/Coast setting is displayed by the Brake/Coast CAL LED, which is in the center of the triangle located at the center of the housing.

-When the DMC60C is connected to a CAN bus the Brake / Coast setting may be overridden by the CAN control frame. When the Brake / Coast override is active the Brake / CAL LED is overridden to display the setting specified by the CAN control frame. During this time the DMC60C employs the Brake / Coast mode that is specified in the CAN frame when applying the neutral duty cycle to the output.+When the DMC60C is connected to a CAN bus the Brake/Coast setting may be overridden by the CAN control frame.
