Error and System Messages
This appendix serves as a guide to error and system messages that can
occur during programming and operation of the 9/Series control. We listed
the messages in alphabetical order along with a brief description.
Important: To display both active and inactive messages, press the
{ERROR MESAGE} softkey found on softkey level 1. For details, see
chapter 2.
Important: This appendix covers only error and system messages.
PAL-generated operator messages generally appear on lines 21 and 22 of
the CRT and should be described in documentation prepared by the
machine tool builder.
Message Description
Symbols
(+) 15V SUPPLY FAILURE + 15 Vdc is not available at the main processor board. Check the wires from the main power
supply and connector CN07 on the main processor board.
(--) 15V SUPPLY FAILURE -- 15 Vdc is not available at the main processor board. Check the wires from the main power
supply and connector CN07 on the main processor board.
(+) OVERTRAVEL PROGRAM ERROR If axis motion continues along the programmed path, the indicated axis will reach or exceed the
positive software overtravel limit (runtime error).
(--) OVERTRAVEL PROGRAM ERROR If axis motion continues along the programmed path, the indicated axis will reach or exceed the
negative software overtravel limit (runtime error).
(+) OVERTRVL PRGRAM ERROR: The end-point of the commanded move will cause the indicated axis to reach or exceed the
positive software overtravel limit (pre-execution error).
(--) OVERTRVL PRGRAM ERROR: The end-point of the commanded move will cause the indicated axis to reach or exceed the
negative software overtravel limit (pre-execution error).
+/-- SIGN ERROR A + or -- sign was found out of place when a numeric value was being decoded. Check the
active program block for programming format errors.

1394 AXIS MODULE MISMATCH At power turn on the system identified an axis module in the 1394 rack that is misconfigured in
AMP. If an extra axis module is present in the 1394 rack it should either be fully configured or
not configured at all in AMP even if that axis module is not used or detached.
1394 RING COMMUNICATIONS ERROR At power up the internal communications ring which runs through the front of the 1394 system
and drive modules was either not connected, a device on the ring experienced a hardware
failure, or a device on the ring was discovered to be misconfigured once a command was sent to
the device. Make sure all axis modules and the end terminator are properly connected to
complete the communication ring.
1746 RACK CARDS MISMATCH The I/O configuration for the 1746 I/O rack that was downloaded from ODS, or resides in the
PAL PROMs, contradicts what is actually in the rack (devices must match slot-for-slot).
1771 RACK CARDS MISMATCH The I/O configuration for the 1771 I/O rack that was downloaded from ODS, or resides in the
PAL PROMs, contradicts what is actually in the rack (devices must match slot-for-slot).
