Chapter 5 Parameter Introductions
deceleration, if the output frequency is at or below the “DC injection braking
frequency at stop, the DC injection braking function will startup.
◆DC injection braking current at stop is a relative percentage of inverter rated current.
The DC injection braking function is disabled, when the braking time is 0.0s. The
setting range of Type G is 0.0～100.0%, and Type P is 0.0～80.0%.
◆DC injection braking time is the DC injection braking holding time. This time cannot
be set too long; otherwise, it will cause the inverter overheating. When the DC
injection braking time is set to zero, the DC injection braking function is disabled.
 Tips:
This function will start up after inverter received stop command. Usually, it is used to
improve the stop precision and not for deceleration braking in common running. If
faster stop required, braking energy regeneration unit should be fitted, or the inverter
that has the function of brake energy regeneration should be selected.
P1.13 Dynamic braking selection
Range: 0,1【1】
0: Dynamic braking is disabled 1: Dynamic braking is enabled
 Tips:
Only valid to inverter that power is lower than 15 kW; If set to 1, entering dynamic
braking automatically in Dec time would improve control capacity.
P1.14 Voltage of working time of braking
Range: 360～750【1 phase:380V
Three-phases: 700V】
P1.14 Utilization ratio of working time of
braking
Range: 0.0～100.0%【100.0%】
Note:
◆Models power equal to 4kW and below: P1.14 is set as braking point voltage , it
cannot be set too low and need consider the inverter model..
◆Models power equal to 5.5kW and above
: Resistance and power of the braking
resistor must be taken into consideration when setting this parameter. If set to 5.0%,
total DC injection braking time in effect will be equal to 5.0s; Start point of DC
injection braking voltage: 710V
P1.15 Trip-free treatment
Range: 0～2【0】
1: In trip-free time give Uu1 alarm,
otherwise report Uu1
0: once trip-free, report Uu1
2: once trip-free, give Uu alarm
