P1.06 Time of S-curve initial
Range: 10.0 ～ 50.0% 【 20.0% 】
P1.07 Time of S-curve rising
Range: 10.0 ～ 80.0% 【 60.0% 】
Note:
P1.06 and P1.07 are only active when the Acc/Dec mode is S-curve mode (P1.05=1) and
P1.06+P1.07
≤ 90%.
Starting process of S-curve is shown in Fig. 5-1-5 as “ ① ”, where the changing rate of
output frequency increases from 0.
Rising process of S-curve is shown in Fig. 5-1-5 as “ ② ”, where the changing rate of
output frequency is constant.
Ending process of S-curve is shown in Fig. 5-1-5 as “
③
”, where the changing rate of
output frequency decreases to zero.
Tips:
Scurve Acc/Dec mode is suitable for the conveying load such as elevator and
conveying belt.

Note:
◆ 0: Dec-to-stop
After receiving the stop command, the ac drive reduces its output frequency within the
Dec time, and stops when the frequency decreases to zero.
