Signals
- Deceleration starting signal
*APDEC<HDI1>
[Classification] Input signal (High-speed DI interface)
[Function] This signal makes the approach speed shift from the parameter value to the
value calculated by gap control.
The high-speed approach operation is ended and the gap control axis starts decelerating.
[Operation] Deceleration starting signal can command to decelerate the gap control axis from the
approach speed when PRM No.15840#2(GDS) is 1.
The signal should be kept 1 at normal status and switched to 0 at deceleration start point.
Switching the signal to 0 makes ending the high-speed approach operation and starting the
deceleration of the axis while switching the deceleration request receive signal (APDON) to
1.
The deceleration starting signal uses HDI1 of high-speed DI interface.
High-speed DI signals except for HDI1 can be used by other functions.
Please refer to FANUC Series 16i-MODEL B connecting manual (hardware) (B-63523) for
details of the high-speed DI interface.
- Pierce point signal
LPP<HDI2>
[Classification] Input signal (High-speed DI interface)
[Function] This signal stops the gap control axis and starts the next block.
[Operation] This signal can stop the approaching of gap control axis when PRM No.15840#4(LPP) is 1.
Switching the signal to 1 during approaching of gap control axis makes quick stop of the gap
control axis and starting the next block.
The pierce point signal uses HDI2 of high-speed DI interface.
High-speed DI signals except for HDI2 can be used by other functions.
Please refer to FANUC Series 16i-MODEL B connecting manual (hardware) (B-63523) for
details of the high-speed DI interface.

The larger the gap control gain is set, the faster the approach speed is and the shorter the approach time is. However, raising the gap control gain too
  • Page 3- High-speed approach operation The approach operation when the gap control axis high-speed approach function is effective is as follows. (1) When the gap control is started, the gap control axis starts the approach operation at the approach speed (PRM No.15845). Please set the acceleration time con
  • Page 4Operation at Pierce point The gap control axis can be stopped at an arbitrary position to pierce a hole while approaching. The procedure is explained with using the following example part program. (1) Specify PRM No.15840#4(LPP) for 1 and specify Pierce point stop signal (NPDS) for 1, and this opera
  • Page 5The gap control axis immediately stops without deceleration when the pierce point signal is set to 1. So, setting the piercing point signal to 1 with the axis moving at high speed might cause shock in the machine. Please slow down the gap control axis by using the deceleration beginning signal (* AP
