4.1 Troubleshooting
● E101.0: parameter error in H02 and above
Cause:
The total number of parameters changes, which generally occurs after software
update.
Values of parameters in groups H02 and above exceed the limit, which generally
occurs after software update.
Cause
Confirming Method
Solution
1. The voltage of the
control circuit power
supply drops
instantaneously.
1. Check whether the control
circuit (L1C, L2C) is in the
process of power‑off or
instantaneous power failure
occurs.
1. Restore default settings
(H02.31 = 1), and write
parameters again.
2. Enlarge the power capacity
or replace with a power
supply of higher capacity,
restore default settings
(H02.31 = 1) and write
parameters again.
2. Measure whether the input
voltage of the control circuit
cable on the non‑drive side is
within the following range:
220 V servo drive:
Value range: 220 V to 240 V
Allowable deviation: –10% to
+10% (198 V to 264 V)
380 V servo drive:
Value range: 380 V to 440 V
Allowable deviation: –10% to
+10% (342 V to 484 V)
Increase the power supply
capacity or replace with a
power supply of higher
capacity. Restore system
parameters to default
settings (H02.31 = 1), and
write parameters again.
2. Instantaneous power
failure occurs when saving
parameters.
Check whether
instantaneous power failure
occurs when saving
parameters.
Power on the system again,
restore system parameters to
default settings (H02.31 = 1),
and write parameters again.
3. The number of write
operations within a certain
period of time exceeds the
limit.
1. Check whether
instantaneous power failure
occurs during parameter
storage.
2. Check whether parameters
are updated frequently
through the host controller.
1. If the servo drive is faulty,
replace the servo drive.
2. Change the write mode
and write parameters
again.
