Description
Acceleration time: The time required to go
from 0% to 100% of the maximum fre-
quency.
Deceleration time: The time required to go
from 100% to 0% of the maximum frequen-
cy.
Note The actual acceleration or decelera- Note The actual acceleration or decelera
tion time is obtained from the follow-
ing formula.
Acceleration/Deceleration time = Acceleration/Deceleration time =
(Acceleration/Deceleration time set
value) × (Frequency reference value)
÷ (Max. frequency)
Used to set S-shape acceleration/decel-
eration characteristics.
0: No S-shape acceleration/deceleration
(trapezoidal acceleration/deceleration)
1: S-shape acceleration/deceleration char-
acteristic time 0.2 s
2: S-shape acceleration/deceleration char-
acteristic time 0.5 s
3: S-shape acceleration/deceleration char-
acteristic time 1.0 s
Note When the S-shape acceleration/de-
celeration characteristic time is set,
the acceleration and deceleration
times will be lengthened according to
the S-shape at the beginning and
end of acceleration/deceleration.
Used to set internal frequency references.
Note Frequency reference 1 is enabled in Note Frequency reference 1 is enabled in
remote mode with n03 for frequency
reference selection set to 1. reference selection set to 1.
Note These frequency references are se-
lected with multi-step speed refer- lected with multi-ste
ences (multi-function input). See the
reference ages for the relationshi reference pages for the relationship
between multi-step speed refer-
ences and frequency references. ences and frequency references.
Used to set the inching frequency com-
mand.
Note The inching frequency command is
selected with the inching command
(multi-function input). The inching
frequency command takes prece-
dence over the multi-step speed ref-
erence.
