7.2.3 Troubleshooting
Take the current operation axis 1 as an example.
E1.101: abnormal system parameter
Cause:
The total number of parameters changes, which generally occurs after software updates.
The actual parameter values of group 2002h and its following groups exceed the limit, which
generally occurs after software updates.
Probable Cause Conrming Method Corrective Action
1. The control
power voltage drops
instantaneously.
Check whether the power is cut off
or whether an instantaneous power
failure occurs.
Restore the default setting
(2002-20h = 1), and rewrite the
parameters.
Measure whether the voltage on
the power supply side is within the
following specications:
380 V drive:
Effective value: 380 to 440 V
Allowed error: -10% to 10% (342 to
484 V)
Increase the power capacity or
replace the power supply with a
large-capacitance power supply.
Restore the default setting
(2002-20h = 1), and rewrite the
parameters.
2. Instantaneous
power failure occurs
during parameter
storage.
Check whether instantaneous power
failure occurs during parameter
storage.
Power on the system again, restore
the default setting (2002-20h = 1),
and rewrite the parameters.
3. The number
of times to write
parameters within
a certain period
exceeds the limit.
Check whether the parameter
update is performed frequently by
the host controller.
Change the parameter writing
method and rewrite parameters.
If the servo drive is faulty, replace it.
4. The software is
upgraded.
Check whether the software is
upgraded.
Reset the servo drive model and the
servo motor model, and restore the
default setting (2002-20h = 1).
5. The servo drive
is faulty.
If the servo drive is powered off and
powered on several times and the
default setting is restored, but the
fault persists, it indicates that the
servo drive is faulty.
Replace the servo drive.
E1.102: Abnormal communication initialization of coprocessor
Cause:
Multi-core communication initialization fault or core software version not matching
Probable Cause Conrming Method Corrective Action
1. The FPGA
software version
and the software
version of CPU
cores do not match.
View the FPGA software version (2001-03h),
the CUP0 software version (2001-04h), and
the CUP1 software version (2001-05h) via the
keypad or the Inovance servo commissioning
software. Check whether the non-zero values
of the most signicant bits are the same in the
two versions.
Contact Inovance for
technical support. Update
the software to make them
match.
2. The FPGA is
faulty.
The fault persists after the servo drive is
powered off and on several times.
Replace the servo drive.
