Tool life count override signals *TLV0 to *TLV9<G154#0, G154#1, G155>
[Classification] Input signal
[Function] If time is specified as the life count type, the life count can be
overridden by setting bit 3 (LFV) of parameter No. 7401 to 1. This
signal consists of ten binary code signals. The signal and override
value are related as follows:

Where:
When *TLVi is 1, Vi = 0.
When *TLVi is 0, Vi = 1.
Each signal has the following weight:
Signal Magnification
*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 20.0.
When all the signals are set to 1, the override value is 0. Set a
value from 0 to 99.9 in 0.1-time steps.
[Operation] The actual cutting time is counted and multiplied by the override value
obtained by the signals. The calculated time is used as the basis for
tool-life management. For example, assume that the override value is
0.1, and the time required for actual cutting is 1000 seconds. Then, the
tool life count time is 100 seconds.
