Section V. Parameter Function Table
forward&reverse rotations
It refers to the transit time at the 0Hz output point when the inverter switches between forward rotation
and reverse rotation. As shown in figure 5-15.

0
☆
Reverse rotation forbidden
1
It is used to set if the inverter could run in reverse rotation state. If reverse rotation is not permitted,
P8.13 should be set to 1.
P8.14

2
It is used to select the running status of the inverter when the set frequency is lower than the
frequency lower limit. HV590 offers 3 kinds of running mode to meet all kins of applications.
P8.15
Droop control 0.00Hz~10.00Hz
0.00Hz
☆
It is used for load distribution when multiple motors drive the same load.
Droop control refers to inverter output frequency decreasing with added load. In this way, motor with
heavy load output frequency decrease more, which could decrease the motor load to realize multiple motor
load uniformity .
This parameter is the output frequency declining value with rated output load.
P8.16
Accumulative power-on time
arrival setup
0h~65000h 0h
☆
When the accumulative power on time (P7.13) reaches the P8.16 set value, inverter multi-function
digital DO would output ON signal.
E.g
：
Inverter outputs fault alarm after 100-hour power-on time
：
Virtual terminal DI1 function
：
user-defined fault1
：
A1.00=44;
Virtual terminal DI1 valid state
：
from virtual DO1
：
A1.05=0000;
Virtual terminal DO1 function
：
power-on time arrived
：
A1.11=24;
Set cumulative power-on time to 100 hours
：
P8.16=100.
When accumulative power-on time reaches 100 hours, inverter outputs fault number 26= E.ArA.
