Cause
Troubleshooting
Solution
1. The phase sequence of
the U, V, and W cables is
incorrect.
Check whether the servo
drive power cables are
connected in the correct
sequence at both ends.
Connect the U, V, and W
cables according to correct
phase sequence.
The interference signal
causes an error in the initial
phase detection of the
motor rotor upon power‑on.
The U/V/W phase sequence
is correct, but E234.0 occurs
when the servo drive is
enabled.
Power off and on the servo
drive again.
3. The encoder model is
wrong or the encoder is
wired improperly.
View the servo drive and
servo motor nameplates to
check whether the devices
used are Inovance SV660F
series servo drive and 23‑bit
servo motor.
Replace with a mutually‑
matching servo drive and
servo motor. For use of of
SV660F series servo drive
and 23‑bit servo motor, set
H00.00 to 14101. Check the
motor model, encoder type,
and encoder cable
connection again.
4. The encoder cable is aged
or corroded, or connected
incorrectly or loosely.
1. Check whether the
encoder cable provided
by Inovance is used and
whether the cable is
aging, corroded, or
connected loosely.
2. Switch off the S‑ON signal
and rotate the motor
shaft manually. Check
whether the value of
H0b.10 (Electrical angle)
changes as motor shaft
rotates.
Re‑solder, tighten or replace
the encoder cable.
5. The gravity load in vertical
axis applications is too large.
Check whether the load of
the vertical shaft is too large.
Adjust brake parameters
H02.09...H02.12 and check
whether the fault is cleared.
Reduce the load of the
vertical axis, increase the
stiffness level, or hide this
fault without affecting the
safety performance and
normal use.
6. Improper parameter
settings lead to excessive
vibration.
The stiffness level is set to
an excessively high value,
leading to excessive
vibration.
Set a proper stiffness level
to avoid excessive vibration.
