Chapter 5 Parameter Introductions
P1.06 Time of S-curve initial
P1.07 Time of S-curve rising
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:
S curve Acc/Dec mode is suitable for the conveying load such as elevator and
conveying belt.
P1.08 Stop mode
0: Deceleration to stop
2: Deceleration +DC braking
Note:
 0: Dec-to-stop

After receiving the stop command, the inverter reduces its output frequency
within the Dec time, and stops when the frequency decreases to zero.
 1: Coast-to-stop
 After receiving the stop command, the inverter stops output immediately and the
load stops under the effects of mechanical inertia.

2: Dec-to-stop +DC injection braking
 After receiving the stop command, the inverter reduces its output frequency
according to the Dec time and starts DC injection braking when its output
frequency reaches the preset frequency of braking.
 Refer to the Notes of P1.09~P1.12 for the functions of DC injection braking.
