15.3 Error Code Table
15.3.1 AMP Errors (From 00FF 0000H)
• Alarms/errors occurred on the AMP side are output from FP7 MC Unit as error codes.
• The AMP errors differ depending on the types of AMP. For details of the processing for AMP
errors, refer to the manual of servo amplifiers.
• When an AMP error occurs, the servomotor automatically becomes free. Execute the servo
on request again after clearing the error.
How to read AMP error codes
• An AMP error is divided into a main code and sub code.
• The error codes stored in the error annunciation area of FP7 MC Unit are hexadecimal 4-
digit codes. The main codes (decimal) of AMP errors are converted to hexadecimal and
stored. The error codes equivalent to sub codes are not stored.
