When the data is set to: 00: 00, the corresponding function does not work.
5.1.15 Historical malfunction
Record the historical
malfunction
information to facilitate the user to findout the cause of the
malfunction
and troubleshoot the peripheral fault.
The controller records up to 100 historical
malfunction
.

Functions description
Motor Variable
Frequency pressure
(
MPa)
00.70
When the pressure fluctuates near the pressure, the controller
adjusts the frequency of frequency
converter, so that the pressure of supply gas is close to the value set
here. (This parameter only works when the motor is variable
frequency or the fan motor is
variable frequency.).
Motor rising rate
1000
When PID is adjusted, it is used to limit the increment of
the result of each PID operation. To prevent the operation of
the air compressor, the
frequency increase too large, resulting in the motor
speed increase too fast.
Motor descent rate
1000
When PID is adjusted, it is used to limit the reduction of
the result of each PID operation. To prevent the operation of
the air compressor, the
frequency is reduced too much, resulting in the motor
speed decline too fast.
Motor Power
(
KW)
022.0
Set the rated power of the motor to calculate the actualpowerof
the motor when it is used in the Variable Frequency operation of the
motor (this parameter only works when the motor is variable
frequency or the fan
motor is variable frequency).
