The Variable Frequency of the wind motor is used to set the variable frequency parameters
of the wind motor.
Before the user modifies the variable frequency parameters of the wind motor, it is
necessary to verify the fan motor Variable Frequency password.
The main functions and functions are shown in the table below:

Fan motor Variable
Frequency temperature
(℃)
0078
Set the exhaust temperature when the air compressor is running
stably. When the exhaust temperature
fluctuates near this value, the controller adjusts the frequency of the
Frequency converter of the wind motor, so that the exhaust
temperature is close to the set value here. (This parameter only
works when the model is set to be variable frequency of the wind
motor, or
the fan motor is variable frequency.)
MAX Variable Frequency
temperature
(℃)
0085
Whentheexhausttemperatureisgreaterthanorequal to this value,
the output frequency of the wind motor Frequency converter is
controlled, which the upper
limit value of the frequency is set in the manufacturer's
parameters. (This parameter only works when the model is set to be
variable frequency of the
wind motor, or the fan motor is variable frequency.)
Fan motor Rising rate
1000
When PID is adjusted, it is used to limit the increment ofthe
resultofeachPIDoperation.Prevent the wind motor operation, the
frequency increase too large, resulting in the wind motor speed
increase too
fast.
Fan motor Descent rate
1000
When PID is adjusted, it is used to limit the reduction of
the result of each PID operation.
Inorderto prevent theaircompressorfrom running, thefrequency
decreasestoomuch,thiscausesthespeed
of the wind motor to drop too fast.
