(5) S-shaped acceleration/deceleration C
When the FR-A5AP is fitted, S-shaped acceleration/deceleration C can be selected by setting "4" in Pr. 29
"acceleration/deceleration pattern". The S-shaped acceleration/deceleration C function allows the speeds of S-
shaped acceleration/deceleration to be set in the corresponding parameters and the required parameter to be
selected by the S-shaped acceleration/deceleration C switching terminal (X20).
Assign the function of the S-shaped acceleration/deceleration C switching terminal (X20) to any of the terminals
using Pr. 180 to Pr. 186 "input terminal function selection".

Also, Pr. 380 to Pr. 383 are used to set the ratio of the S-shaped acceleration/deceleration time (Ts) to the

Note: During acceleration/deceleration, switching cannot be made using the S-shaped acceleration/deceleration C
switching terminal (X20). When X20 is switched either ON or OFF during either acceleration or deceleration, the
effect of the switch (to select a different acceleration or deceleration shape) does not take effect until either the
acceleration or deceleration has stopped (i.e. a stable speed has been reached).
