corresponds to neutral. When a neutral pulse width is detected, the present Brake/Coast setting is

applied to the output. The DMC60C expects the PWM Input Signal to have an input period between

2.9 and 100 milliseconds. The allows te update rate to be as high as 344 Hz or as low as 10 Hz.

The DMC60C's Input Signal Cable features a 0.1" pitch 3-pin female header that is compatible with

most RC / PWM Servo Controllers, allowing the DMC60C to be readily wired directly to those

devices. The Input Signal Cable consists of two wires, the signal wire (yellow), and the ground wire

(green).

4 Motor Controller LEDs

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:
