12.1.3 LED Indicators (MP2200/MP2300)
For explanations of the LED indicators on MP2100M and MP2500MD respectively, refer to Machine Controller
MP2100/MP2100M User’s Manual Design and Maintenance (manual number SIEP C880700 01) and Machine Con-
troller MP2500/MP2500M/MP2500D/MP2500MD User’s Manual (manual number SIEP C880752 00).
( 1 ) LED Indicators
( 2 ) LED Indicator Meanings
The following table shows how to use the LED indicators to determine the operating status of the MP2200/MP2300, as
well as relevant error information when the LED indicator status indicates an error.
The status of the LED indicators on the front of the MP2200/MP2300 can be used to determine
the error status and meaning.
The locations in the program that need to be corrected can be determined by using the LED indi-
cator status to determine the general nature of the error, using the contents of system (S) registers
to check drawings and function numbers causing the error, and knowing the meaning of opera-
tion errors.
