14.30 Real-Time Tuning 2 (Rapid Traverse Time Constant)
The acceleration/deceleration time constant is not switched in the following cases.
 When the derivative calculation of the optimum time constant is not completed. (The derivative calculation of the optimum
time constant will be executed at the next timing for the switch, and then the acceleration/deceleration time constant will be
changed.)
 When the inertia estimation is stopped.
The acceleration/deceleration time constant is set to the maximum value of time constant in the following cases.
(Acceleration/deceleration time constant reset)
 When the acceleration/deceleration time constant reset signal is commanded by PLC signal.
 When "#1428 RT2rst (time constant reset) is set to "1". (The acceleration/deceleration time constant will be the maximum
value of time constant at the time of reset commanded.)
