This group of function codes are used to realize sleep and wake up function.
During operation
：
when set frequency is less than or equals to sleep frequency(P8.51), inverter would
step into sleep state and stop after sleep delay time(P8.52).
If inverter is in sleep state and current running command is valid, when set frequency is no less than
P8.49 wake-up frequency, inverter will start to run after P8.50 wake-up delay time.
Generally, please set wake-up frequency no less than sleep frequency. Sleep function and wake-up
function are valid when both wake-up frequency and sleep frequency are set to 0.00 Hz.
When enabling sleep function(frequency source
：
PID) , PID calculation selection in sleep state is
influenced by function code PA.28(PA.28=1).

When the running time reached the P8.53 set value, inverter multi-function DO
output “Then running

P9.00=0
：
Without motor overload protection function. It is recommended to install a thermal relay
between the motor and the inverter.
P9.00=1
：
The inverter has overload protection function for the motor according to motor overload
protection inverse time limit curve.
Motor overload protection inverse time limit curve
：
220%×(P9.01)× motor rated current,it will report
motor overload fault after it lasts for one minute. When the operating current of the motor reaches the
current of 150%×(P9.01)times the rated current of the motor, it will report motor overload after it lasts 60
minutes.
Users can set value of P9.01 according to the motor actual overload ability.If the parameter is set too
big, it may cause danger of motor overheating damage without inverter fault report.
P9.02
Motor overload pre-alarm
coefficient
50%~100%
80%
☆
This function is used before motor overload fault by giving pre-alarm signal through multi-function
terminal DO.This pre-alarm coefficient is used to determine the warning timing before motor overload
protection. The higher the value,the shorter the warning timing will be.
When the inverter output current is accumulated more than the product of inverse time limit curve with
P9.02,multi-
function terminal DO output “Motor overload pre-alarm”ON signal.
P9.03
Over-voltage stall gain
0(no over-voltage stall)~100
