When the temperature of the inverter radiator reaches the temperature, the multi-function
terminal HDO output "module temperature overheat" of ON signal.
Cooling fan working
mode
P8-48
Setting Range
The parameter sets cooling fan operation mode, when the value set to 0, inverter in the
running state makes fan to work, When the drive stops, the fan works if heatsink
temperature is above 40°C and stops if heatsink temperature is below 40°C.
When the value set to 1, the fan keeps working after power-on.

Hibernating frequency
P8-51
Setting Range
Hibernating delay time
P8-52
Setting Range
The hibernating and wakeup function is used in water supply application.
During drive running, when frequency reference is equal to or smaller than P8-51, the
Inverter enters hibernating state after delay set in P8-52.
In hibernating state a, if run command is valid, when frequency reference is equal to or
larger than P8-49, the AC drive wakes up after delay set in P8-50.
Generally, set wakeup frequency equal to or higher than hibernating frequency. If they are
set to 0, the function is disabled.
When frequency reference setting channel is PID reference, whether to perform PID
operation in hibernating state is determined by PA-28, perform PID operation in stop
state(PA-28 = 1).
Group P9:Fault and Protection
Motor overload protection Factory default
P9-00
Setting Range
Motor overload protection
gain
P9-01
Setting Range
P9-00 = 0:No motor overload protection, there may be the risk of overheating damage to
the motor, it is recommended install a thermal relay between inverter output (U, V, W) and
the motor.
P9-00 = 1: At this point, the inverter will judge whether the motor is overloaded according
to the inverse time limit curve of the motor overload protection.
The inverse time limit curve of motor overload protection is: 220% * (P9-01) * motor rated
