Error and System Messages

B-4
Message Description
AXIS INVALID FOR G24/G25 The programmed axis was not AMPed for software velocity loop operation, and can not be used
in a G24 or G25 block. To use these features the axis programmed must be configured for
tachless operation (or be a digital servo).
AXIS IS HARD STOPPED, CANT ADJUST SERVO The torque limit of the servo can not be adjusted because, either the axis is in a hard--stopped
state, or some other axis on the same servo card is in a hard--stopped state.
AXIS MODULE POWER FAULT The current through the power output transistors is monitored. If the current exceeds a fixed
level (greater than 300% of controller rating) this fault will appear. Typical causes are a shorted
lead, motor malfunction, or malfunctioning power IGBTs.
AXIS MODULE OVER CURRENT One of the axis modules of your 1394 drive has been requested to provide too much current.
This is typically caused by Accel/Decel command from the CNC is requiring peak current for an
excessive amount of time, the machine friction or inertial/viscous load is excessive, the motor
has been improperly sized, a short circuit exists across the drive output terminals, logic supply
circuits have malfunctioned, or AC input is incorrectly wired.
AXIS MODULE BUSS VOLTAGE LOSS The DC bus supply was lost to the axis module. Check slider connections/termination strip or
there could be a blown link fuse.
AXIS MODULE OVER TEMP The 1394 contains a thermal sensor which senses the internal ambient temperature. Causes
could be: that the cabinet ambient temperature is above rating. The machine duty cycle
requires an RMS current exceeding the continuous rating of the controller. The airflow access to
the 1394 is limited or blocked. This does not necessarily indicate a motor over temperature.
Motor over temperture sensors should be wired directly into the E-Stop string.
AXIS MOVER CONFLICT WITH G16.3/G16.4 You have requested a PAL axis mover function on an angled wheel grinder. You can not use the
PAL axis mover in one of the angled wheel modes unless the PAL axis mover has control of
both the axial and the wheel axes.
AXIS NAME DUPLICATE Two or more axes have been assigned the same name in AMP.
AXIS NOT IN PROCESS You attempted to read/write a paramacro parameter for an axis that is not currently in the
process requesting the data. To access paramacro parameter data for an axis, that axis must
be in the process making the request.
AXIS POSITION INCORRECT Using the mid-start program function, you have searched to a block that does not create the
programmed contour if started from your current axis position. Be aware the mid-start operation
may have searched thru a offset operation that is not readily apparent to determine your axis
position. The mid-start operation is aborted. You must re-perform the mid-start operation and
either position the axes to the correct axis position, or use the {MOVE & EXIT} softkey to find the
correct axis position.
AXIS SELECT NOT ALLOWED The {AXIS SELECT} softkey was pressed when no axis select option is available. Axis select is
only available on large screens and normal character size screen for systems that contain more
then 9 axes total or dual process systems with more than 8 axes in a process. It is not available
when the small screen (showing all system AMPed axes) is being viewed.
AXIS TYPE-POSITION LOOP ERROR In patch AMP, an axis was assigned a position loop type that is illegal for the axis type assigned
to that axis.
B
BACKUP VERSION OF AMP WAS COPIED TO RAM The AMP in RAM was erased (battery backup failed) or corrupted, so the control automatically
copied the version of AMP in backup memory into RAM memory. (The control stores AMP in
backup, but works from the copy of AMP in RAM memory.)
BAD DAC MONITOR PATCH AMP ENTRY An invalid value was entered into patch AMP parameter #86 or #87. Either parameter allows
the axes to be monitored through the servo module (DAC) analog output. See documentation
provided by Allen-Bradley on patch AMP, or contact Allen-Bradley customer support service.
BAD FIRST POCKET BLOCK When performing an irregular pocket cycle, the first pocket block should be away from the
pocket start/end corner, not toward it. The move to the start/end corner is generated based on
the coordinates programmed in the pocket definition block itself.
BAD PAL PROM One of the PAL PROM chips (plugged into the main processor board) has failed or is not
plugged in properly.
