Exponential Acceleration/Deceleration with Constant Acceleration/
Deceleration Time
With exponential acceleration/deceleration, the rate of acceleration/deceleration is deter-
mined by the Speed set in parameter Pn821 and the Time Constant for Exponential Curve set
in parameter Pn840. The Time Constant for Exponential Curve set in Pn840 is set to the time
required to reach 63.2% of the Speed set in Pn821.
If this acceleration/deceleration pattern is used, the time of acceleration/deceleration will
remain constant even if the Speed set in Pn821 is changed.
