Details
Remedy
0001
DOG OVERRUN (Dog overrun)
When returning to the reference point‚
the near-point detection limit switch did
not stop over the dog‚ but overran the
dog.
• Increase the length of the near-point
dog.
• Reduce the reference point return
speed.
0002
Z-AX NO CRSS
One of the axes did not pass the
Z-phase during the initial reference point
return after the power was turned ON.
• Move the detector one rotation or more
in the opposite direction of the reference
point‚ and repeat reference point return.
0003
INVALID RET (Invalid return)
When manually returning to the
reference point‚ the return direction
differs from the axis movement direction
selected with the AXIS SELECTION
key.
• The selection of the AXIS SELECTION
key’s +/– direction is incorrect. The error
is canceled by feeding the axis in the
correct direction.
0004
EXT INTRLK (External interlock)
The external interlock function has
activated (the input signal is "OFF") and
one of the axes has entered the interlock
state.
• As the interlock function has activated‚
release it before resuming operation.
• Check the sequence on the machine
side.
• Check for broken wires in the interlock
signal line.
0005
INTRL INTRLK (Internal interlock)
The internal interlock state has been
entered.
The absolute position detector axis has
been removed.
A command for the manual/automatic
simultaneous valid axis was issued from
the automatic mode.
• The servo OFF function is valid‚ so
release it first.
• An axis that can be removed has been
issued‚ so perform the correct
operations.
• The command is issued in the same
direction as the direction where manual
skip turned ON‚ so perform the correct
operations.
• During the manual/automatic simul-
taneous mode‚ the axis commanded in
the automatic mode became the manual
operation axis. Turn OFF the manual/
automatic valid signal for the
commanded axis.
• Turn ON the power again‚ and perform
absolute position initialization.
