Fig. 6-5 linear Acc/Dec
1:
S curve mode
In Acc/Dec process, the relationship between output frequency and Acc/Dec time is
nonlinear. The output frequency increases or decreases according to the S curve shown
in Fig. 6-6.
Fig. 6-6 S curve Acc/Dec
P1.10 Time of S curve’ s start part
Setting range: 10.0 ~ 50.0 % (Acc/Dec time)
P1.11 Time of S curve’ s rising part
Setting range: 10.0 ~ 80.0 % (Acc/Dec time)
The function codes of P1.10 and P1.11 define the Acc/Dec parameters of S curve.
S curve start time is shown in Fig. 6-6 as
①
, which is the stage when the slope of output
frequency rises gradually.
S curve rise time is shown in Fig. 6-6 as
②
, which is the stage when the slope of output
frequency maintains phase.
S curve end time is shown in Fig.6-6 as
③
, which is the stage when the slope of output
frequency decreases to zero.
Note:
1. Limit of setting value: S curve start time + S curve rise time
≤

%
(Acc/Dec time).
