Solution
Re-back up the data on the
keypad.
Check the related settings;
Check the surrounding
environment, and
interference effects
Check the related settings;
Check the communication
set mode selection;
Check the surrounding
environment, and
interference effects
Check the line: switch on the
matching resistor.
Set the same baud rate;
Check the surrounding
environment, and
interference effects
Check whether the motor wiring
is normal
Replace the hall component;
Replace the main control board.
Check the load to ensure it is
proper, and increase
detection time;
Check whether the
parameters are set properly.
Check the load and ensure the
set
load is normal;
Check whether the
parameters are set correctly;
Increase the maladjustment
detection time.
Check the load and overload
pre-alarm threshold
