Title
Draw
The T series has two tool change types (the turret type and the ATC type). The turret type
uses only a T code to select a group, specify a tool offset value, and start tool life counting,
whereas the ATC type, like the M series, uses a T code to select a group and an M06
command to start tool life counting. With the ATC type, only the D code is used as a code
for specifying a tool offset value. The tool change type is selected by bit 3 (TCT) of
parameter No. 5040.
CAUTION
This function cannot be used when bit 1 (LGN) of parameter No.
5002 is set to 1 to use the same number as the tool selection number
to specify a geometric offset number.
- Life management B function
If the tool life management B function is enabled, the maximum tool life value can be
extended, and the tool life arrival notice signal can be output to post the arrival of the life
limit in advance when the remaining life (the life value minus the life counter value) has
reached the remaining life setting. The remaining life setting is registered as tool life
management data in the CNC in advance.
The tool life management B function is enabled by setting bit 4 (LFB) of parameter No.
6805 to 1.
If the tool life management B function is enabled, the function for selecting a tool group by
an arbitrary group number can be used.
The tool life management B function can be used. However, the function for selecting a
tool group by an arbitrary group number can be used only when the tool change type is the
ATC type (bit 3 (TCT) of parameter No. 5040 = 1).
- Maximum number of tool life management groups and multipath system
Up to 256 tool life management groups can be used in the entire CNC system.
For each path, set a maximum number of groups to be used in parameter No. 6813.
The maximum number of groups must be a multiple of the minimum number of groups
(eight groups). If the maximum number of groups is 0, the tool life management function
is disabled.
The total number of groups in the entire CNC system can be expanded to 1024 groups by
using an option for additional tool life management groups.
