1:
Dec-to-stop mode 2
After the inverter receives stop command, it lowers its output frequency and decelerates
to stop according to the preset Dec time. During Dec process, when output frequency is
equal to the frequency set by P1.06, the inverter starts DC braking according to the DC
braking time and voltage defined by P1.07 and P1.08.
2:
Free run to stop
After the inverter receives the stop command, it stops its output immediately; the
motor will decelerate to stop according to its inertia.
P1.06 Initial frequency of DC injection braking
Setting rang: 0.00~20.00Hz
Initial frequency of DC injection braking: It is the frequency when the inverter's output
frequency is decreased to zero along the Dec curve in Dec-to-stop process, which is shown in Fig.
6-4.
In the process of Dec-to-stop, when the preset frequency is lower than the initial frequency
of Stop DC injection braking, the inverter‘s output frequency is decreased to zero.
If the running condition has no strict requirements for braking, the initial frequency of DC
injection braking should be set as low as possible.
P1.07 DC injection braking time
Setting range: 0.0, 0.1~60.0s
P1.08 DC injection braking current
Setting range: 0.0~100.0% (inverter‘s rated current)
DC injection braking time: the time for maintaining output DC injection braking in inverter's
stopping process.
DC injection braking current: percentage of braking voltage when the inverter stops in DC
injection braking mode.
When the DC injection braking time is set to 0 second., the DC injection braking function is
disabled.
P1.09 Acc/Dec mode selection
Setting range: 0, 1
Acc/Dec modes 0 and 1 are valid in Start, Stop, FWD/REV, Acc and Dec process.
0:
linear mode
In Acc/Dec process, the relationship between output frequency and Acc/Dec time is
linear. The output frequency increases or decreases at the constant slope as shown in
Fig. 6-5.
