6.2.2 Troubleshooting
1. Er.101: Groups H02 and above parameters abnormal
Cause:
•
Total number of function codes changes, which generally occurs after software update.
•
The actual values of groups H02 and above parameters exceed the limit, which generally
occurs after software update.
Cause Conîš¿rming Method Corrective Action
1. The control
power voltage drops
instantaneously.
•
Check whether it is in the
process of cutting off the
control power (L1C, L2C) or
whether instantaneous power
failure occurs.
Restore the default setting (H02-31 =
1), and write the parameters again.
•
Measure whether the control
power voltage on the non-drive
side is within the following
speciîš¿cations:
220 V drive:
Effective value: 220 to 240 V
Allowed error: -10% to 10%
(198 to 264 V)
380 V drive:
Effective value: 380 to 440 V
Allowed error: -10% to 10%
(342 to 484 V)
Increase the power capacity or replace
with large-capacitance power supply,
restore the default setting (H02-31 =
1), and write the parameters again.
2. Instantaneous power
failure occurs during
parameter storage
•
Check whether instantaneous
power failure occurs during
parameter storage.
Re-power on the system, Restore the
default setting (H02-31 = 1), and write
the parameter again.
3. The times of
parameter writing
within a certain period
exceeds the limit.
•
Check whether parameter
update is performed frequently
from the host controller.
Change the parameter writing method
and write parameters again.
If the servo drive is faulty, replace it
4. The software is
upgraded.
•
Check whether the software is
upgraded.
Set the servo drive model and motor
model again, and restore the default
setting (H02-31 = 1).
5.The servo drive is
faulty.
•
If the servo drive is powered off
and powered on gain several
times and the default setting is
restored, but the fault remains,
it indicates that the servo drive
is faulty.
Replace the servo drive.
