This manual is a guide for using the MITSUBISHI CNC M800/M80 Series.
This manual is prepared on the assumption that your machine is provided with all of M800/M80 Series functions. Confirm the
functions available for your NC before proceeding to operation by referring to the specification issued by the machine manufacturer.
Notes on Reading This Manual
(1) This manual explains general parameters as viewed from the NC.
For information about each machine tool, refer to manuals issued from the machine manufacturer.
If the descriptions relating to "restrictions" and "allowable conditions" conflict between this manual and the machine manufacturer's instruction manual, the later has priority over the former.
(2) This manual is intended to contain as much descriptions as possible even about special operations.
The operations to which no reference is made in this manual should be considered impossible.
CAUTION
For items described as "Restrictions" or "Usable State" in this manual, the instruction manual issued by the machine tool
builder takes precedence over this manual.
Items not described in this manual must be interpreted as "not possible".
This manual is written on the assumption that all option functions are added.
Refer to the specifications issued by the machine tool builder before starting use.
Refer to the Instruction Manual issued by each machine tool builder for details on each machine tool.
Some screens and functions may differ depending on the NC system (or its version), and some functions may not be possible. Please confirm the specifications before use.

Some screens and functions may differ depending on the NC system (or its version), and some functions may not be pos-
sible. Please confirm the specifications before use.
(2) Adjustments
Do not adjust or change the parameter settings greatly as operation could become unstable.
In the explanation on bits, set all bits not used, including blank bits, to "0".
(3) Troubleshooting
If the battery low warning is issued in the controller side, save the machining programs, tool data and parameters in an
input/output device, and then replace the battery. When the battery alarm is issued, the machining programs, tool data and
parameters may have been destroyed. Replace the battery and then reload the data.
If the battery low warning is issued in the drive unit side, immediately replace the battery. Replace the batteries while applying the drive unit's control power.

overran the dog.
Remedy
Increase the length of the near-point dog.
Reduce the reference position return speed.
M01Some ax does not pass Z phase0002
Details
One of the axes did not pass the Z-phase during the initial reference position return after the power was turned
ON.
Remedy
Move the detector one rotation or more in the opposite direction of the reference position, and repeat reference position return.
M01R-pnt direction illegal0003
Details
When manually returning to the reference position, the return direction differs from the axis movement direction
selected with the AXIS SELECTION key.
Remedy
The selection of the AXIS SELECTION key's +/- direction is incorrect. The error is canceled by feeding the
axis in the correct direction.
M01External interlock axis exists0004
Details
The external interlock function has activated (the input signal is "OFF") and one of the axes has entered the
interlock state.
Remedy
As the interlock function has activated, release it before resuming operation.

part systems.
Selected an axis other than the 1st axis when the manual speed command was issued.
A travel command has been issued to an axis stopped by the collision detection function.
Remedy
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 simultaneous 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.
Turn OFF the "tool length measurement 1" signal to start the program by the manual speed command.

was validated.
The sensor signal turned ON at a position within 100 μm from the final entry start position.
Remedy
Turn the tool measurement mode signal input OFF, and move the axis in a safe direction.
Disabling the sensor signal also clears the operation alarm.
(Note) When the "tool length measurement 1" signal is disabled, the axis can be moved in either direction. Pay

Y07Too many axes connected00xy
Details
The number of axes connected to each channel exceeds the maximum number of connectable axes.
The exceeded number of axes per channel is displayed as alarm No.
x: Exceeded number of axes at drive unit interface channel 2 (0 to F)
y: Exceeded number of axes at drive unit interface channel 1 (0 to F)
This alarm also occurs when the drive unit is connected only with the 2nd channel without connecting with the
1st channel.
Remedy
Remove connected axes from the channel whose alarm No. is other than '0' for the number displayed as the
alarm No. Keep the number of connected axes to or less than the maximum that can be connected.
(Note 1) The number of axes is limited per each drive unit interface channel.
(Note 2) Maximum number of axes that can be connected differs depending on whether or not an expansion
unit is available or the setting of '#11012 16 axes for 1ch (Connecting 16 axes for 1ch)'.
With the expansion unit, up to eight axes can be connected to a channel. Without the expansion unit, up
to eight axes are allowed when '#11012 16 axes for 1ch (Connecting 16 axes for 1ch)' is set to '0', sixteen
axes when set to '1'.
(Note 3) If this alarm occurs, the alarm 'Y03 Message: Drive unit unequipped' will not occur.
(Note 4) This alarm is displayed taking precedence over the alarm 'Y08 Too many drive units connected' and
'Y09 Too many axisno connected'.

The exceeded number of drive units per channel is displayed as alarm No.
x: Exceeded number of drive units at drive unit interface channel 2 (0 to F)
y: Exceeded number of drive units at drive unit interface channel 1 (0 to F)
Remedy
Remove drive units from the channel whose alarm No. is other than "0" for the number displayed as the alarm
No. Keep the number of connected drive units to 8 or less.
(Note 1) The drive unit is not counted when all the axes connected to it are invalid.
(Note 2) If this alarm occurs, the alarm "Y03 Message: Drive unit unequipped" will not occur.
(Note 3) The alarm "Y07 Too many axes connected" and "Y09 Too many axisno connected" are displayed tak-
ing precedence over this alarm.
Y09Too many axisno connected00xy
Details
The No. of the axis (drive unit's rotary switch No.) connected to each channel is bigger than the No. allowed.
If the axis No. of each channel is bigger than the No. allowed, "1" is displayed for the alarm No.
x: "1" when the axis No. at drive unit interface channel 2 is too big
y: "1" when the axis No. at drive unit interface channel 1 is too big
Remedy
For the channel whose alarm No. is "1", keep the axis No. (drive unit's rotary switch No.) not bigger than the
No. allowed.
(Note 1) The axis No. is limited per each drive unit interface channel.
(Note 2) The biggest allowed connected axis No. differs depending on whether or not an expansion unit is avail-
able or the setting of "#11012 16 axes for 1ch (Connecting 16 axes for 1ch)". The biggest connectable
axis No. is as shown below.
With the expansion unit, axes No. '0' to '7' can be connected.
Without the expansion unit, axes No. '0' to '7' are allowed when '#11012 16 axes for 1ch (Connecting 16
axes for 1ch)' is set to '0', axes No. '0' to 'F' when set to '1'.
(Note 3) If this alarm occurs, the alarm "Y03 Message: Drive unit unequipped" will not occur.
(Note 4) This alarm is displayed taking precedence over the alarm "Y08 Too many drive units connected".
(Note 5) The alarm "Y07 Too many axes connected" is displayed taking precedence over this alarm.

Some contactors take a while to be shutdown after the servo ready is turned OFF, and the servo ready was
turned ON in the meantime.
Remedy
Make sure that contactor's auxiliary B contact signal is output correctly to the device set on "#1330

24VDC power is not supplied to SDIO connector correctly. (SDIO 4A pin supply voltage was dropped to 16V
or less, or 1ms or more instant power interrupt was detected.)
In this case, "Pw sply:Inst pw interpt(DC24V)" alarm occurs because the contactor control output signal cannot
be controlled.
