The drive incorporates four sets of individually programmable acceleration and deceleration times.
Four acceleration and deceleration times can be selected if two Multi-Function Input Terminals
(n050 to n056) are set to ‘11’ (accel/decel time 1) and ‘27’ (accel/decel time 2).
B. n050 thru n056 : Multi-function Inputs Data 11 : Accel/Decel Time Selection 1
(Term. S1 thru S7)
Data 27 : Accel/Decel Time Selection 2
The following table shows which acceleration and deceleration times are selected by each
combination of accel/decel time select 1 (n050 thru n056 =11) and accel/decel time select 2
(n050 thru n056 = 27).
Accel/decel time Accel/decel time
Select 1 (terminal S1 Select 2 (terminal S1 Acceleration time Deceleration time
thru S7) thru S7)
OPEN OPEN Acceleration time 1 Deceleration time 1
n019 n020
CLOSED OPEN Acceleration time 2 Deceleration time 2
n021 n022
OPEN CLOSED Acceleration time 3 Deceleration time 3
n041 n042
CLOSED CLOSED Acceleration time 4 Deceleration time 4
n043 n044
C. n018 : Accel Time Setting Unit Factory setting: 0
Range : 0 = 0.1 seconds
1 = 0.01 seconds
In addition to determining the setting resolution, this parameter controls the range of n019 thru n022;if
the resolution is 0.01 sec., the range is 0.00 to 600.00 sec. If the resolution is set to 0.1 sec., the range
is 0.0 to 6000.0 sec.
