Inovance SV660F Series - Fault Code Details

Description of Fault Codes

4. The software is updated.
Check whether parameter
values in group H02 and
above exceed the upper/
lower limit due to software
update.
Reset the servo drive model
and servo motor model, and
restore system parameters to
default settings (H02.31 = 1).
5. The servo drive is faulty.
If the fault persists though
parameters are restored to
default settings and the servo
drive is powered off and on
repeatedly, the servo drive is
faulty.
Replace the servo drive.
● E101.1: parameter error in group H00/H01
Description:
The total number of parameters changes, which generally occurs after software
update.
Values of parameters in groups H00 or H01 exceed the limit, which generally
occurs after software update.
Cause
Troubleshooting
Solution
The servo drive detects
whether parameter values in
groups H00 and H01 exceed
the upper/lower limit during
initialization upon power‑
on. If yes, the keypad
displays E101.1. Motor
parameters in group H00 are
read from the encoder.
Servo drive parameters in
group H01 are mapped
based on the servo drive
model defined by H01‑10.
Check groups H00 and H01
to find the parameter whose
value exceeds the limit.
Confirm whether this
parameter range is
abnormal.
Replace the motor or servo
drive.
● E101.2: Address error in read/write operation after the number of parameters
changes
Description:
Address error in read/write operation after the number of parameters changes.
Cause
Troubleshooting
Solution
The total number of
parameters changes after
software update, leading to
address error in read/write
operation.
Read H0b.90 and H0b.91
and obtain the abnormal
parameter group number.
Rectify the wrong values.
Restore default settings.
● E102.0: FPGA communication establishment error
