7-4 Responding to an Error Message
This describes the error messages that may appear on the
machine’s display screen, and how to take action to rem-
edy the problem. If the action described here does not
correct the problem, or if an error message not described
here appears, contact your authorized Roland DG Corp.
dealer.
[Emergency Stop COVER OPEN]
An emergency stop occurred because the front cover
was opened while the spindle was rotating.
Operation cannot be continued. Switch the power off and
back on, then redo the operation from the start.
☞ P. 40, "Starting and Quitting"
[Emergency Stop S-overload[*]]
An emergency stop occurred because of a spindle-
motor error.
This is caused by prolonged high load on the motor or by
excessive torque being applied momentarily. Resuming is not
possible. Switch the power off and back on, revise the cut-
ting parameters, then redo the operation from the start.
If this message persists even after revising the cutting param-
eters, contact your authorized Roland DG Corp. dealer.
Note: The kind of load applied is indicated as “S” (short), “L”
(long), “P” (peak), or “T” (temperature).
☞ P. 40, "Starting and Quitting"
[Emergency Stop Z AXIS error]
An emergency pause occurred because Z-axis descent
failed to stop.
Resuming is not possible. The spindle head may be locked
while automatic Z control is set to "ON." Switch the power
off and back on, then check the position of the lock lever for
the spindle head. After checking, redo the operation from
the beginning.
If this message continues to appear, contact your authorized
Roland DG Corp. dealer.
☞ P. 40, "Starting and Quitting," p. 82, "The Position of the Lock
Lever," and p. 108, " Examples of Settings for Cutting Parameters"
[Emergency Stop RPM error]
An emergency stop occurred because rotation of the
spindle failed to reach the specified rpm.
Operation cannot be continued. The cause is a motor error
or the like. Switch off the power and contact your autho-
rized Roland DG Corp. dealer.
☞ P. 41, "Shutdown"
[Cannot find *- LIMIT SW]
An emergency stop occurred because initialization
failed.
Switch the power off, remove any cutting waste or other ob-
structions impeding operation of the spindle head, then redo
the operation from the start. If the message persists even af-
ter redoing the operation from the beginning, contact your
authorized Roland DG Corp. dealer.

[I/O Err:Framing/Parity Error]
This is displayed when the parameter settings for
communication with the computer are unsuitable.
Pressing pauses the machine. Because unin-
tended operation may occur, we recommend using the
“pause” menu displayed on the screen to select “STOP” and
quit operation.
Revise the communication parameters on the machine and
the computer (the settings for baud rate, parity, number of
stop bits, and data bit length). When a serial connection is
used, this error message may appear if the computer is re-
started while the machine is powered up.
☞ P. 50, "Stopping Cutting," p. 85, "Submenus"
[I/O Err:Buffer Overflow]
The machine’s memory experienced an overflow.
Pressing pauses the machine. Because unin-
tended operation may occur, we recommend using the
“pause” menu displayed on the screen to select “STOP” and
quit operation.
Possible causes include unsuitable communication param-
eters for a serial connection. Revise the communication pa-
rameters on the machine and the computer (the settings for
baud rate, parity, number of stop bits, and data bit length).
