F2.07 Rising time of S ramp Range:10~80%【60.0%】
F2.06 and F2.07 are only active when the Acc/Dec
mode is S-ramp Acc/Dec mode(F2.05=1), and
F2.06+F2.07≤90%.
Starting process of S-shape curve is shown in Fig. 5-15
as “①” , where the change rate of output frequency
increases from 0;
Rising process of S-shape curve is shown in Fig. 5-15
as “②”, where the output frequency’s changing rate is
constant;
Ending process of S-shape curve is shown in Fig. 5-15
as “③”, where the changing rate of output frequency
decreases to 0;
S-ramp Acc/Dec mode is suitable for the conveying load
such as elevator and conveying belt.
F2.08 Stopping mode Range:0. 1. 2【0】
0: Dec-to-stop
After receiving the stopping command, the drive reduces
its output frequency according to the Dec time, and
stops when the frequency decreases to 0.
1: Coast-to-stop
After receiving the stopping command, the drive stops
outputting power immediately and the motor stops under
the effects of mechanical inertia.

2: Dec-to-stop+DC injection braking
After receiving the STOP command, the drive reduces
its output frequency according to the Dec time and starts
DC injection braking when its output frequency reaches
the initial frequency of braking process.
Refer to the introductions of F2.09~F2.12 for the
functions of DC injection braking.

Range: dependent on

F2.12 DC injection braking

Range: dependent on
drive’s model【0.0s】
DC injection braking waiting time at stop: The duration
from the time when operating frequency reaches the DC
injection braking initial frequency(F2.09) to the time
when the DC injection braking is applied.
The drive has no output during the waiting time. By
setting waiting time, the current overshoot in the initial
stage of braking can be reduced when the drive drives a
high power motor.
The range of DC injection braking current and time are
dependent on drive’s model, see Table 5-2.
DC injection braking current at stop is a percentage of
drive’s rated current. There is no DC injection braking
when the braking time is 0.0s.

F2.13 Dynamic braking Range:0,1【0】
0: Dynamic braking is disabled
1: Dynamic braking is enabled
Note:
This parameter must be set correctly according to the actual
conditions, otherwise the control performance may be
affected.
F2.14 Ratio of working time of braking
kit to drive’s total working time
Range:0.0~
100.0%【2.0%】
This function is effective for the drive with built-in braking
resistor.
Note:
Resistance and power of the braking resistor must be taken
into consideration when setting this parameters.
