•
Total number of function codes is abnormal at EEPROM reading/writing operation.
•
The setting range of function codes is abnormal, which generally occurs after software
update.
Cause Conrming Method Corrective Action
1. An EEPROM fault
occurs.
Check the causes according to the
method of Er.101.
Restore the default setting
(H02-31 = 1), and power on the
servo drive again.
2. The servo drive is
faulty.
The fault remains after the drive is
powered off and powered on again
several times.
Replace the servo drive.
5. Er.108: Parameter storage fault
Cause:
•
Parameter values cannot be written to EEPROM.
•
Parameter values cannot be read from EEPROM.
Cause Conrming Method Corrective Action
1. EEPROM writing is
abnormal.
Modify a parameter, power on the servo
drive again, and check whether the
modication is saved.
If the modication is not saved
and the fault remains after
the servo drive is powered off
and powered on again several
times, replace the servo drive.
2. EEPROM reading is
abnormal.
6. Er.120: Product model matching fault
Cause:
•
The rated motor current is larger than the rated current of the servo drive.
Cause Conrming Method Corrective Action
1. The product (motor
or servo drive) SN does
not exist.
•
View the servo drive and motor
nameplates and check that the
equipment you are using is the
IS620P series servo drive and 20-
bit servo motor (-U2***) of Inovance.
Meanwhile, check whether H00-00
(Motor SN) is 14000.
The motor SN does not exist.
If you use the IS620P series
servo drive and 20-bit servo
motor (-U2***) of Inovance,
ensure that H00-00 = 14000.
•
View the servo drive SN (H01-02)
and check whether the servo drive
SN exists by referring to section 2.3.
The servo drive SN does not
exist. Please set the servo
drive SN correctly by referring
to section 2.3.
2. The power classes of
products such as motor
and servo drive do not
match.
•
Check whether the servo drive
SN (H01-02) and the bus motor
SN (H00-05) match by referring to
section 2.3.
Replace the unmatched
product by referring to section
2.3.
