■ E3.120: product model matching fault
Cause:
The motor model and drive model do not match or the parameter setting is incorrect, or the inverter module
recognition is incorrect.
Probable Cause ConrmingMethod Corrective Action
1. The product (encoder,
motor or servo drive) SN
does not exist.
Internal fault code 200B-2Eh=1120
Viewthemotornameplatetocheckwhether
themotorissuitable.Checkwhether2000-01h
setting is correct.
Set 2000-01h (Motor SN) correctly
according to the motor nameplate or
use a matching motor.
Internal fault code 200B-2Eh=2120
To view the drive model (2001-0Bh), please
refer to the "1.1 Model and Nameplate
Description of the Servo Drive" section on page
9tocheckwhetherthisdrivemodelexists.
If the drive SN does not exist, set
it correctly by referring to the "1.1
Model and Nameplate Description
of the Servo Drive" section on page
9.
2. The power rating of the
servo motor and does
not match that of the
servo drive.
Internal fault code 200B-2Eh=3120
Checkwhetherdrivemodel(2001-0Bh)
matches serial bus motor model (2000-06h)
by referring to the "1.1 Model and Nameplate
Description of the Servo Drive" section on page
9andthe"1.3SpecicationsoftheServo
Motor" section on page 13.
Replace products that are not
matching by referring to the "1.4
TableofServoSystemConguration
Specications"sectiononpage21.
3. Settings of inverter
model do not match
auto recognition results.
Checkwhetherfaultyaxis2001-10hand2001-
62h are the same.
Set 2001-10h the same as 2001-62h.
Replace the inverter module.
■ E3.121: invalid S-ON command
Cause:
When some auxiliary functions are used, a redundant S-ON signal is given.
Probable Cause ConrmingMethod Corrective Action
1. When the servo drive is
enabled internally, the
S-ON signal is turned on
via communication.
CheckwhethertheS-ONsignalissentfrom
the host controller when the auxiliary functions
(200D-03h, 200D-04h, 200D-0Ch) are used.
Turn off the S-ON signal from the
host controller.
■ E3.122: product matching fault in the absolute position mode
Cause:
The motor does not match in the absolute position mode or the motor SN is set incorrectly.
Probable Cause ConrmingMethod Corrective Action
1. The motor does not match in
absolute position mode or the
motor SN is set incorrectly.
Viewthemotornameplatetocheck
whether the motor is a multi-turn
absolute encoder motor.
CheckwhetherH0000(MotorSN)is
correct.
Set H0000 (Motor SN) correctly
according to the motor nameplate or
use a matching motor.
