  • Page 2Outline The approach speed of the gap control function is controlled according to the value multiplied the gap control gain and the gap deflection. 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
  • Page 6Signals - Deceleration starting signal *APDEC [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.

  • Page 7- Deceleration request receive signal NPDS [Classification] Input signal [Function] This signal notifies admitted input of Pierce point signal (LPP) to PMC. [Operation] The gap control axis is stopped if Pierce point signal is input when this signal is 1. The Pierce point signal is not acce
