Accel/Decel Time - YASKAWA V7 Technical Manual

5.2 ACCEL/DECEL TIME

A. n019 : Accel Time 1
n020 : Decel Time 1
n021 : Accel Time 2
n022 : Decel Time 2
n041 : Accel Time 3
n042 : Decel Time 3
n043 : Accel Time 4
n044 : Decel Time 4
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
(Term. S1 thru S7)
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).

C. n018 : Accel Time Setting Unit
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.
