14.30 Real-Time Tuning 2 (Rapid Traverse Time Constant)
Also, when the following conditions are satisfied, the acceleration/deceleration time constant is switched to the maximum
value of switching time constant "tmax" or the minimum value of switching time constant "tmin".
 When the estimated inertia ratio exceeds "#2400 RTJX" (Real-time tuning: maximum adaptive inertia ratio), the accelera-
tion/deceleration time constant will be the maximum value of switching time constant "tmax". (Refer to "Relation between
the estimated inertia ratio and optimum time constant" as shown in the previous figure)
 When the estimated inertia ratio is smaller than "#2237 JL" (Load inertia scale), the acceleration/deceleration time constant
will be the minimum value of switching time constant "tmin". (Refer to "Relation between the estimated inertia ratio and opti-
mum time constant" as shown in the previous figure)
 When tmin ≥ tmax, the acceleration/deceleration time constant will be the maximum value of switching time constant
"tmax".
 When tmax- tmin ≤ trng, the acceleration/deceleration time constant will be the maximum value of switching time constant
"tmax".
 When the value of tmax, tmin or trng is changed, the acceleration/deceleration time constant will be the maximum value of
switching time constant "tmax".
The setting values of "#2004 G0tL" (G0 time constant), "#2007 G1tL" (G1 time constant) and "#2158 G1btlx" (Per-axis pre-
interpolation cutting feed time constant) are not changed.
