Title

Tool life count override signals *TLV0 to *TLV9 <Gn049#0 to Gn050#1>
[Classification] Input signals
[Function] When the life count type is the duration specification type, the life count can be
overridden if bit 2 (LFV) of parameter No. 6800 is set to 1. Ten binary code
signals are used, and they correspond to override values as follows:
Override value
9
0i
{ 2
i
V
i
} times
where, if *TLVi is "1": Vi=0
if *TLVi is "0": Vi=1
Therefore, each signal has the following weight:
Signal Magnifi-
cation
*TLV0 0.1
*TLV1 0.2
*TLV2 0.4
*TLV3 0.8
*TLV4 1.6
*TLV5 3.2
*TLV6 6.4
*TLV7 12.8
*TLV8 25.6
*TLV9 51.2
Example: When *TLV7, *TLV6, and *TLV3 are set to "0", the override value is
calculated as follows:
12.8+6.4+0.8=20.0
The life count is multiplied by 20.
When all signals are set to "1", the override value is 0. Set an override value
within the range from 0 to 99.9 in steps of 0.1.
[Operation] The actual cutting time obtained by life counting by duration is multiplied by
the override value specified by these signals, and the multiplication result is
assumed to be the count time of tool life management. For example, let the
override value be 0.1, and the actually cutting time be 1000 seconds. Then, the
tool life count time is assumed to be 100 seconds.
