Acceleration and Deceleration Operations
Section 7-4
Exponential Acceleration/Deceleration Curve
The acceleration/deceleration for the exponential acceleration/deceleration
curve is determined by the Servo Parameters
Exponential Accelera-
tion/Deceleration Bias (Pn810) and Exponential Acceleration/Deceleration
Time Constant (Pn811). The speed set in Exponential Acceleration/Decelera-
tion Bias (Pn810) is used as the start speed. The time until reaching 63.2% of
the difference between the speed command value and the start speed is set
in the
Exponential Acceleration/Deceleration Time Constant (Pn811).
When an exponential acceleration/deceleration curve is used, the accelera-
tion/deceleration time is always fixed regardless of the speed command value.
