Cause
Corresponding resistor is not
dialed
The communication baud
rate is uneven
The ambient interference is
too strong.
The Ethernet communication
is not selected to right.
The ambient interference is
too strong.
The connection is not sound
The communication baud
rate is uneven
The ambient interference is
too strong.
PID1 feedback value
continues P22.45 and is
smaller than P22.44
PID1 feedback value
continues P22.47 and is
larger than P22.46

Solution
Draw out the correspond resistor
Set the same baud rate
Check the environment and
avoid the interference.
Check the communication
method selection.
Check the environment and
avoid the interference.
Check the connection
Set the same baud rate
Check the environment and
avoid the interference.
Check PID1 actual feedback
value is normal
Check PID1 feedback detection
device has no fault
Check PID1 actual feedback
value is normal
Check PID1 feedback detection
device has no fault
