Fan drive
● Compared with fan speed control by the belt drive, fan
speed control by the direct drive has a wider application
range which is not subject to the transmission ratio.
● The fan is controlled over RS485. You can view the fan
power and speed in real time on the display module and
can obtain fault information including fan blockage,
overvoltage, and undervoltage. The features allow you to
view the status and locate a fault.
