6.2.4 Axis LED is red or Status LED shows a flashing symbol
If an axis LED is illuminated red and/or the Status display shows a flashing symbol, use the Error Log tool in WorkBench v5 to view a list of recent errors. Alternatively, type
PRINT AXISERROR and PRINT MISCERROR as separate commands in the WorkBench v5 Command window. Each of these commands will return an error code, a description of which can be found in the help file.
Press F1 and locate the AXISERROR and MISCERROR keywords. The Error Handling book contains topics listing the Status display indicators and basic error codes. Remember that many error codes are the sum of a bit pattern so may not be listed individually. For help on understanding bit pattern values, see the Bit pattern values topic in the Keywords book.
