Limitation

Correct setting of an entry-inhibition area

If an entry-inhibition area is incorrectly set, it may not be possible to make the area effective. Avoid
making the following settings:
-

L < L1 or W < W1 in the chuck-shape settings.

D2 < D3 in the tail stock-shape settings.

A chuck setting overlapping that of the tail stock.

When you use only the chuck or only the tail stock

Setting of direction of entry-inhibition area for a chuck and of entry-inhibition area for a tail stock is
decided by a big and small relation between CZ and TZ. Even when you use only the chuck or only the
tail stock, please set a big and small relation between CZ and TZ appropriately. Please refer to "Setting of
direction of chuck and of tail stock" for details.

If you not use the entry-inhibition area for a chuck, please set 0 to L, L1, W and W1 of the chuck-shape
settings.
If you not use the entry-inhibition area for a tail stock, please set 0 to L, L1, L2, D, D1, D2 and D3 of the
tail stock-shape settings.

Retraction from the entry-inhibition area

If the tool enters the entry-inhibition area and an alarm is issued, switch to manual mode, retract the tool
manually, then reset the system to release the alarm. In manual mode, the tool can be moved only in the
opposite direction to that in which the tool entered the area.
The tool cannot be moved in the same direction (further into the area) as it was traveling when the tool
entered the area.
When the entry-inhibition areas for the chuck and tail stock are enabled, and the tool is already positioned
within those areas, an alarm is issued when the tool moves.
When the tool cannot be retracted, change the setting of the entry-inhibition areas, such that the tool is
outside the areas, reset the system to release the alarm, then retract the tool. Finally, reinstall the original
settings.

Coordinate system

An entry-inhibition area is defined using the workpiece coordinate system. Note the following.
<1> When the workpiece coordinate system is shifted by means of a command or operation, the

entry-inhibition area is also shifted by the same amount.

Machine coordinate system

Entry-inhibition
area

Old workpiece
coordinate system

Entry-inhibition
area

New workpiece
coordinate system

Fig. 2.3.11 (f)

Use of the following commands and operations will shift the workpiece coordinate system.
Commands:

G54 to G59, G52, G50 (G92 in G code system B or C)

Operations:

Manual handle interrupt, change in offset relative to the workpiece reference point, change in
tool offset (tool geometry compensation), operation with machine lock, manual operation with
manual absolute signal off

<2> When the tool enters an entry-inhibition area during automatic operation, set the manual absolute

signal, *ABSM <Gn006.2>, to 0 (on), then manually retract the tool from the area. If this signal is
“1”, the distance the tool moves in manual operation is not counted in the tool coordinates in the
workpiece coordinate system. This results in the state where the tool can never be retracted from the
entry-inhibition area.

Warning

WARNING

1 If an alarm is issued, the tool stops before it enters the entry-inhibition area when

bit 7 (BFA) of parameter No. 1300 is set to 1.

When bit 7 (BFA) of parameter No. 1300 is set to 0, an actual stop position can
be in the entry-inhibition area beyond the specified profile because the CNC and
machine system stop with some delay in time. For this reason, for safety, set
profile data a little larger than the actual profile. The extra distance, L, required for
this purpose is calculated from a rapid traverse rate as follows:
L = (rapid-traverse-rate)

1/7500

For example, when a rapid traverse rate of 15 m/min is used, set profile data 2
mm larger than the actual profile.
The profile of a chuck or tail stock can also be set using parameters Nos. 1330 to
1348.

ALARM SIGNALS

When an alarm is triggered in the CNC, the alarm is displayed on the screen, and the alarm signal is set to
“1”.
If the voltage level of the memory backup battery falls to below a specified level while the CNC is turned
off, the battery alarm signal is set to “1”.

Signal

Alarm signal AL<Fn001.0>

[Classification] Output signal

[Function] The alarm signal reports that the CNC is in an alarm state.

The following are the alarms that may be issued:
(a)  TH alarm
(b)  TV alarm
(c)  P/S alarm
(d)  Overtravel alarm
(e)  Overheat alarm
(f)  Servo alarm

[Output cond.] The alarm signal is set to “1” when:

The CNC is placed in the alarm state.

The alarm signal is set to “0” when:
-

The alarm has been released by resetting the CNC.

Battery alarm signal BAL<Fn001.2>

[Classification] Output signal

[Function] The battery alarm signal indicates that the voltage of the battery for the memory has

fallen to below a specified level while the CNC is off. In general, this signal is used to
turn on an LED to notify the operator.

[Output cond.] The signal is set to “1” when:

The battery voltage has fallen to below the specified level.

The signal is set to “0” when:
-

The battery voltage has risen to the specified level or higher.
