Exponential Acceleration/Deceleration with Bias with Constant
Acceleration/Deceleration Time
With exponential acceleration/deceleration with bias, the rate of acceleration/deceleration is
the same as described in
f
, but a bias is applied. The Time Constant for Exponential Curve
set in parameter Pn840 is set to the time required to reach the following speed.
Speed = Bias Speed set in Pn841 + (Speed set in Pn821 - Bias Speed set in Pn841)
×
0.632
If this acceleration/deceleration pattern is used, the acceleration/deceleration time will
remain constant even if the Speed set in Pn821 is changed. If the Bias Speed set in Pn841 is
set to 0, then the acceleration/deceleration pattern will be the same as the exponential accel-
eration/deceleration pattern described in
f
.
