System Messages - Alphabetical List *Unexpected end of file* (-504) Explanation: (1) If a file was being loaded from the disk, the end of the file was encountered unexpectedly. (2) If a program is reading a file, this error code merely indicates that the end of the file has been reached and should not be interpreted as a real error. (3) This message results if a CTRL+Z is pressed in response to a program PROMPT. (4) A break condition was detected on a serial line. User action: (1) Try again to read the file. (2) Close the file and continue program execution. (3) Treat the program as having been aborted early by user request. *Unexpected PSS state* Code nnn (-1110) Explanation:
The software has detected an unexpected change in the power sequencing control hardware. The code value indicates what state has been encountered. This error should never be seen, and may indicate a software or hardware problem on either the AWC or CIP. User action: If safe to do so, attempt to enable HIGH POWER and note any different error messages which occur. If this error persists, contact Omron Adept Customer Service. *Unexpected text at end of line* (-451) Explanation: The previous command or instruction cannot be recognized by eV+, possibly because of a mistyped function name or because an argument was specified where none is allowed. User action:
Reenter the line, correcting the syntax error. *Unexpected zero index* Belt n (-1012) Explanation: A zero index signal was received from the encoder for this motor belt at an unexpected time. The encoder may be gaining or losing counts, there may be a hardware problem with the zero index signal, or the Counts per zero index configuration parameter may be set incorrectly. User action: Continue to use the system. Contact Omron Adept Customer Service if this error occurs repeatedly. *Unexpected zero index* Mtr n (-1005) Explanation: A zero index signal was received from the encoder for this motor at an unexpected time.
The encoder may be gaining or losing counts, there may be a hardware eV+Language Reference Guide, v2.x, 18319-000 Rev A Page 658
