Er.520 Vibration alarm
1. If conditions permit, reduce motor speed or reduce speed loop gain.
2. Correctly set the moment of inertia ratio.
3, set the vibration detection value (Pn187) and the sensitivity of vibration
detection (Pn186) appropriately.

Overload
(instantaneous
maximum load)
1.Check if the motor is blocked during running
2. Check if there is any problem with the motor wiring (phase sequence and
connection) and encoder wiring.
3. Consider the operating conditions and load to determine whether the driver or
motor is selected properly
4. Observe whether the motor has a large jitter during the operation and whether
there is a large noise. If so, adjust the gain parameters to eliminate noise or jitter.
At the same time, use a virtual oscilloscope to monitor the motor output torque
for abnormalities.

Er.730 DB overload 1
1, overloading when shutting down, resulting in overload of DB resistance,
trying to reduce operation speed or reduce load.
2, check whether the motor is driven by external force.
3, according to the needs of customers, we need to re evaluate whether we need
to go through the DB mode when stopping. If we don't need it, we can stop in
other ways.
4. If the fault is reported in the last operation, then a power up operation is
running.

Er.7A0 Radiator overheat
1, with a fan drive, check whether the air duct is blocked, and whether the fan is
damaged.
2, check the installation conditions of the driver, whether the heat dissipation
condition is good, and improve the heat dissipation condition of the driver as
much as possible.
3, check the driver's carrying condition. If the load is too heavy, you can suggest
that the customer replace the driver with high power section.
