5-6 Setting the Acceleration/Deceleration Time
The following description provides information on parameters related to
acceleration and deceleration time settings.
Trapezoidal
and S-shape acceleration and deceleration are available. Us -
ing the S-shape characteristic function for acceleration and deceleration
can reduce shock to the machinery when stopping or starting.
H Setting the Acceleration/Deceleration Time (n16 through n19)
•Two acceleration times and two deceleration times can be set.
•The
acceleration time is the time required to go from 0% to 100% of the maximum fre -
quency and the deceleration time is the time required to go from 100% to 0% of the
maximum
frequency . The actual acceleration or deceleration time is obtained from the
following formula.
Acceleration/Deceleration time = (Acceleration/Deceleration time set value)
×
(Frequency reference value) ÷ (Max. frequency)
Acceleration time 2 and deceleration time 2 are enabled by setting 1 1 for acceleration/
deceleration time selection in any of the n36 through n39 parameters for multi-function
input.
Deceleration time 2 is also enabled by emergency-stop settings 19, 20, 21, and 22 in
any
of the n36, n37, n38, and n39 parameters for multi-function input with n04 for inter -
ruption mode selection set to 0 (i.e., deceleration stop).
