Chapter 5 Detailed Function Introductions

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.
P1.16 Stopping holding frequency
Setting range: 0~Maximum frequency [0.00Hz]
P1.17 Stopping holding time
Setting range:0~3600.0s [0.0s]
Notes:
The stopping holding frequency: under the conditions of press the STOP key or other normal stopping, the
operation frequency will drop to stopping holding frequency, then drop to 0.
When stopping holding time is 0, stopping holding frequency is invalid; when current setting holding
frequency is greater than the operation frequency, stopping holding frequency is invalid.
P1.18 Dynamic braking selection
Setting range: 0,3 [3]
0: Dynamic braking is disabled
1: Dynamic braking is enabled
2: Use flux brake
3: Use energy consumption and flux brake
Tips:
On occasions where the load inertia is not great and there is no special requirements on the deceleration time,
magnetic flux braking can be used only without connecting braking resistor; while on occasions where the
rotary inertia is great, and fast stopping is required, it is suggested to set the parameter to 1 or 3 and select the
matching dynamic braking unit and braking resistor.
15kW and below models is designed with built-in braking unit.
P1.19 Dynamic braking usage
Setting range: 30.0% to 100.0% [100.0%]
Notes:
The larger the set value is, the better the braking effect will be got, but the temperature rise of the braking
resistor will be greater. Therefore, setting of this parameter should consider the impedance and power of the
braking resistor, choose the appropriate usage to achieve a balance between rapid braking and avoiding
braking resistor overheat.
Dynamic braking operation voltage point relates to stall overvoltage point (Pd.11). For 380V input models,
dynamic braking operation voltage point is about 52V lower than stall overvoltage point (namely the default
operation point is 700V); for 220V input models, dynamic braking operation voltage point is about 23V lower
than stall overvoltage point (namely the default operation point is 350V). Please see Pd.11 description for
more details.
P1.20 Trip-free handling
Setting range: 0 ~ 2 [ 0]
0: It will be fault Uu1 after Trip-free
1: Give an alarm Uu within instantaneous stop time, and give
fault Uu1 afterwards;
2: It will give an alarm Uu after Trip-free
P1.21 Trip-free time
Setting range: 0.5-10.0s [This value depends on the inverter
model]
