Tool axis direction tool length compensation amount modification handle mode signal
CNGTL<G156#3>
[Classification] Input signal
[Function] Selects tool axis direction tool length compensation amount
modification handle mode.
[Operation] If this signal is set to 1 when the following conditions are satisfied, tool
axis direction tool length compensation amount modification handle
mode is set:
1. Manual handle interrupt mode is set.
2. Tool axis direction tool length compensation mode (G43.1)
is set.
3. The axis selection signal of the first manual pulse generator
is set to the value set in the parameter (No. 7556).
NOTE
If more than one of the tool axis direction handle
mode signal (ALNGH), tool axis right-angle direction
handle mode signal (RGHTH), tool tip center rotation
handle mode signal (RNDH), and tool axis direction
tool length compensation value modification mode
signal (CNGTL) are set to 1, none of these modes are
set. Instead, normal handle feed mode is set.
