This set of parameters is used to implement sleep and wake-up functions in water supply
applications.
During the running of the inverter, when the set frequency is less than or equal to the
sleep frequency of P8-51, after the delay time of P8-52, the inverter enters the sleep
state and stops automatically.
If the inverter is in the sleep state and the current running command is valid, when the
set frequency is greater than or equal to the P8-49 wake-up frequency, after the delay
time of the time P8-50, the inverter starts to start.
In general, please set the wake-up frequency to be greater than or equal to the sleep
frequency. When the wake-up frequency and sleep frequency are both set to 0.00 Hz,
the sleep and wake-up functions are invalid.
When the sleep function is enabled, if the frequency source uses the PID, whether the
sleep state PID is calculated or not is affected by the function code PA-28. At this time,
the PID stop operation (PA-28=1) must be selected.

When the running time of this startup reaches this time, the inverter outputs the "this
running time arrives" ON signal.

There is no motor overload protection function, there is a danger of motor
overheating damage. It is recommended to heat the relay on the motor;
1: At this time, the inverter judges whether the motor is overloaded according to the
inverse time curve of the motor overload protection. The shortest time to report motor
overload is 2 minutes. If you need to adjust the motor overload current and time, please set
P9-01.
(Be careful to confirm whether the rated current of the motor is correct before setting.)
Reduce the value of P9-01 to make the motor protection advance. The user needs to
correctly set the value of P9-01 according to the actual overload capacity of the motor. The
motor is overheated and the inverter is not alarming!

When the output power (U0-05) does not correspond to the expected value, the output power
can be linearly corrected by this value.
