P8-12
Positive reversal dead
time
0.0s
～
3000.0s
Default
：
0.0s
Set the transition time at the output 0Hz during the forward/reverse transition of the
inverter, as shown in Figure 6-15:

P8-13
Reverse control enable
0
：
Allow 1: Prohibit
Default
：
0
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.
P8-14
The set frequency is
lower than the lower limit
frequency.
0: Run at the following frequency limit
1: Stop
2: Zero speed operation
Default
：
0
When the set frequency is lower than the lower limit frequency, the running status of
the inverter can be selected by this parameter.
P8-15
Droop control
0.00Hz
～
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.
P8-16
Set
the
cumulative
power-on arrival time
0h
～
65000h
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.
