E1.602: Angle auto-tuning failure
Cause:
Abnormal jitter is reported by the encoder during the angle auto-tuning.
Probable Cause Conrming Method Corrective Action
Abnormal encoder
feedback data
Check if the encoder communication is
interrupted.
Check the encoder
hardware wiring
E1.610: Servo drive overload
Cause:
Heat accumulation of the servo drive reaches the fault level.
E1.620: Motor overload
Cause:
Heat accumulation of the motor reaches the fault level.
Probable Cause Conrming Method Corrective Action
1. Wiring of the
motor and encoder
is incorrect or in
poor contact.
Check wirings between the servo drive,
servo motor and 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 outputting
effective torque
higher than the
rated torque for a
long time.
Conrm the overload characteristics of the
servo drive or servo motor.
Check whether the average load ratio
(200B-0DH) remains greater than 100.0%
for 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 a
single run.
4. The gain 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.
