(3) Adjusting the multi-step acceleration/deceleration time constants
[1] Measure the acceleration/deceleration waveform to the spindle's maximum rotation speed
using S command operation. (No. 1 spindle, No. 2 spindle)
Example of spindle acceleration/deceleration wa veform
[2] Calculate the multi-step acceleration/deceleration pattern based on the acceleration/
deceleration waveform for the spindle with a long acceleration/deceleration time.
Calculation of multi-step acceleration/deceleration
[3] Set the actual acceleration/deceleration time constant in the parameters while maintaining a
50% margin from each time constant calculated in step [2].
Setting the multi-step acceleration/deceleration parameters
[4] Try spindle synchronous acceleration/deceleration operation with the actual machine, and
confirm that the speed is accelerated or decelerated at 50% or less of the load meter value. If
the load meter value exceeds 50%, adjust the time constant again.
