Fig. 6-5 linear Acc/Dec
1:
S curve mode (reserved)
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).
2. In Acc/Dec Process, the parameters of S curve are set in symmetry.
P1.12 Restart after power failure
Setting range: 0, 1
0: Disabled;
1: Enabled; Function of restarting after power failure is enabled when the power supply
recovers.
P1.13 Delay time for restarting after power failure
Setting range: 0.0~20.0s
When the power recovers from failures, the time before the inverter restarts is the delay time.
This time is set according to the time needed by other equipment to recover when the power
supply recovers.
