Chapter 9 Troubleshooting
The load is too heavy.
The motor keeps output
of effective torque higher
than the rated torque for a
long time.
Confirm the overload
characteristic and
operation instructions of
the servo drive or servo
motor.
Increase the drive, motor capacity,
reduce the load, increase the
acceleration and deceleration time.
The acceleration/
deceleration is too
frequent or the load
inertia is too large.
View inertia ratio, confirm
start-stop cycle
Increase the acceleration and
deceleration time.
The gain adjustment is
inappropriate, the rigidity
is too strong, the motor
vibrates and the sound is
abnormal
Observe whether the
motor vibrates and
generates noise during
running.
The servo drive or motor
model is set incorrectly.
The motor block occurs
due to mechanical
factors, resulting in very
heavy load during
running.
Check the running
reference and the
actual motor speed by
using the drive debugging
platform or the operation
panel.
Eliminate mechanical factors.
Note:You can clear the fault or re-power on the system 60s after occurrence of the overload
fault.
The read/write error of
the control parameters
occurs.
Confirm whether the
instantaneous power
failure occurs in the
process of writing
parameter.
After restoring the default parameter
(P02.22), re-enter the parameters.
Writing parameter times
exceeds the maximum
within a certain time.
Confirm whether the
change of parameters is
frequent from the host
device.
Change the parameter writing
method and write again.
Abnormal serial
port
communication
Improper setting of
communication
parameters.
Confirm the function code
setting.
Set the correct baud rate,
communication data format, etc.
