Acceleration and deceleration rounded corners: the time P40.10 - P40.13 of the arc segment added to
improve the smoothness of the beginning and end segments of the acceleration and deceleration
process. The arc segment curve time is suitable for conveyors carrying fragile items or for
applications requiring smooth velocity regulation.
P40.10 - P40.13 are the S-curve (velocity curve) parameters during motor operation when the switch
multi-speed set is set. They specify the acceleration time (P40.02), deceleration time (P40.03),
speed-up rounded corner time (P40.10 and P40.11), and deceleration rounded corner time (P40.12
and P40.13). These parameters directly affect the characteristics of S curve and therefore also
directly relate to the running efficiency and riding comfort of motor. The specific positions of the
above parameters in the motor operation S-curve are shown in Figure 7-20.
P40.14 parameter is mainly used for the elevator application scenario: P40.14=1, acceleration state
rounding corner suppression; P40.14=2, deceleration state rounding corner suppression; P40.14=3,
enabling both acceleration and deceleration state rounding corner suppression.

By setting of P40.15 and P40.16, P40.04 - P40.09 acceleration and deceleration can be corresponded
according to actual speed.
