Er.104: Programmable logic interruption
Cause Conrming Methods Corrective Action
1. The FPGA is faulty (E4.104).
The fault persists after you
power on the servo drive several
times.
Replace the servo
drive.
2. The communication between the FPGA and the
MCU is abnormal (Er.100).
3. The drive internal operation times out (Er.940).
Er.105: Internal program abnormal
Cause Conrming Methods Corrective Action
1. An EEPROM fault
occurs.
Check causes according to the method
of Er.101.
Restore default setting (H02-31 = 1), and
power on the servo drive again.
2. The servo drive is
faulty.
The fault persists after you power on
servo drive several times.
Replace the servo drive.
Er.108: Parameter storage fault
Cause Conrming Methods Corrective Action
1. EEPROM writing is abnormal.
Modify a parameter, power on
servo drive again, and check
whether modication is saved.
If modication is not saved and the fault
persists after servo drive is powered on
several times, replace the servo drive.
2. EEPROM reading is abnormal.
Er.120: Product model matching fault
Cause Conrming Methods Corrective Action
1. Product (motor or
servo drive) SN does
not exist.
View servo drive and servo motor nameplates
to check that the equipment you are using is
IS650P series servo drive and 20-bit servo
motor (-U2***) of Inovance. Meanwhile, check
whether H00-00 (Motor SN) is 14000.
Servo motor SN does not exist. If you
use IS650P series servo drive and 20-
bit servo motor (-U2***) of Inovance,
ensure that H00-00 = 14000.
View servo drive SN (H01-02) and check
whether servo drive SN exists.
Servo drive SN does not exist. Set
servo drive SN correctly.
Power class of servo
motor and servo drive
does not match.
Check whether servo drive SN (H01-02) and
serial encoder motor SN (H00-05) match.
Replace unmatched product.
Er.121: S-ON signal invalid
Cause Conrming Methods Corrective Action
When servo drive is enabled
internally, external S-ON
signal is valid.
Check whether auxiliary functions (H0D-02,
H0D-03, H0D-12) are used and whether DI
function FunIN.1: S-ON is ON.
Set DI function FunIN.1: S-ON (both
hardware DI and virtual DI) to OFF.
Er.122: Product matching fault in absolute position mode
Cause Conrming Methods Corrective Action
The motor in absolute position
mode does not match or motor
SN is set incorrectly.
Check whether motor nameplate is multi-turn
absolute encoder motor.
Check whether H00-00 (motor SN) is correct.
Set H00-00 correctly or replace
matching motor according to
motor nameplate.
