6.8 Approximate S-shaped Acceleration/Deceleration Function
The approximate S-shaped acceleration/deceleration reduces the load applied on the motor at the start of
operation and the stop of operation.
When the acceleration/deceleration mode (BFM#3 b6 or BFM#37 b6) is ON, both acceleration and
deceleration become approximate S-shaped acceleration/deceleration control.
1. Positioning operations for which approximate S-shaped acceleration/deceleration function
can be used
2. Operation
*1. When the acceleration time and the deceleration time are set individually by using the extension
positioning parameter, the approximate S-shaped acceleration/deceleration is executed at the value
set for the acceleration time.
