■ E3.602: Angle auto-tuning failure
Cause:
Abnormal jitter is reported by the encoder during the angle auto-tuning.
Probable Cause ConrmingMethod Corrective Action

Checkiftheencodercommunicationis
disturbed.
Checktheencoderhardware
wiring.
■ E3.610: Servo drive overload
Cause:
Heat accumulation of the servo drive reaches the fault level.
■ E3.620: Motor overload
Cause:
Heat accumulation of the motor reaches the fault level.
Probable Cause ConrmingMethod Corrective Action
1. Wiring of the motor and
encoder is incorrect or in
poor contact.
Checkwiringsbetweentheservodrive,theservo
motor and the encoder according to the correct
"wiring diagram."
Connect the wirings according
to the correct wiring diagram.
Preferably use the cables
recommended by Inovance.
When self-made cables are
used, prepare and connect
the cables according to the
hardware wiring instructions.
2. The load is too heavy.
Themotorkeepsoutput
of effective torque higher
than the rated torque for
a continuous operation.
Conrmtheoverloadcharacteristicsoftheservo
drive or motor.
Checkwhethertheaverageloadratio(200B-0DH)
is larger than 100% for a long time.
Use a servo drive of larger
capacity and matching servo
motor.
Reduce the load and increase
the acceleration/deceleration
time.
3. Acceleration/deceleration
is too frequent or the load
inertia is too large.
Calculate the mechanical inertia ratio or perform
the inertia auto-tuning. Then view 2008-10h (load
inertia ratio).
Checkthesinglerunningcyclewhentheservo
motor runs circularly.
Increase acceleration/
deceleration time during single
running.
4. The gain adjustment is
improper, or the stiffness
is too high.
Checkwhetherthemotorvibratesandproduces
abnormal noise during running.
Re-adjust the gain.
5. The servo drive or motor
model is set incorrectly.
View the bus motor model in 2000-06h and servo
drive model in 2001-0Bh.
View the servo drive nameplate
and set the servo drive model
in 2001-0Bh correctly and use a
matching servo motor according
to Section 2.3.
