FRONT PANEL INDICATORS
There are 14 green and red light emitting diodes (LEDS) on the front panel of the MMC120. These LEDS
provide status information about the module and each of the two axes.
The LED labeled "F" is the FAIL indicator for the MMC120 microprocessor. If the FAIL indicator is red, the
drive outputs are disabled and the axes will not move unless the valve is out of null.
The LED labeled "Active" indicates the status of communications over the backplane. When this LED is
green, communication is normal. When it is off, communication has stopped.
The numbered LEDS indicate the status of the axes.
NOTE: There are three transducer errors: No Transducer, Transducer Noise, and Transducer Overflow. The default
AUTO STOP settings will make any of these errors cause a Hard Stop, set the output of the axis to the
current drive null, and turn on its red LED. Once the transducer error has been corrected, a new command
to the axis will turn the red LED off.

outputs disabled
