Set the transition time at the output 0 Hz during the forward/reverse
transition of the inverter, as shown in Figure 6-17.

Use this parameter to set whether the inverter is allowed to run in the
reverse state. If the motor is not allowed to reverse, set P8-13=1.

Running mode when
set frequency lower

limit
Default
:
0
0: Run at the following
frequency limit
1: Stop
2: Zero speed operation
When the set frequency is lower than the lower limit frequency, the
running status of the inverter can be selected by this parameter.

Droop control

10.00Hz
Default
:
0.00Hz
This function is generally used for load distribution when multiple motors
are dragging the same load.
The droop control means that as the load increases, the output frequency
of the inverter decreases, so that when multiple motors are dragged by the
same load, the output frequency of the motor in the load drops more, thereby
reducing the load of the motor and realizing the operation of multiple motors.
The load is even.
This parameter refers to the frequency drop value of the output when the
inverter outputs the rated load.

Default
:
0h
When the accumulated power-on time P7-13 reaches the power-on time
set by P8-16, the inverter multi-function outputs ON signal.

Accumulative running
time threshold
When the accumulated running time P7-09 reaches this set running time, the
inverter multi-function outputs ON signal.
Used to set the running time of the inverter.

If the parameter is set to 1, if the running command of the inverter is valid
(for example, the terminal running command is closed before power-on), the
inverter does not respond to the running command, and the running
command must be removed once. After the running command is valid again.
The inverter responds.
This parameter relates to the safety protection function of the frequency
converter.
