Solution
supply line;
Reset the rated current of the
motor
Check the load and adjust the
torque lift
Increase the ACC time;
Avoid the restarting after
stopping;
Check the power of the
supply line;
Select an inverter with bigger
power;
Select a proper motor
Check input power;
Check installation distribution
Check the output distribution;
Check the motor and cable
Dredge the air duct or change
the fan;
Low the ambient temperature
Check the external device
input
Set proper baud rate;
Check the communication
connection distribution;
Set proper communication
address;
Change or replace the
connection distribution or
improve the anti-interference
capability
Check the connector and
repatch;
Change the Hoare;
