Description of Fault Codes
‑84‑
● EB01.4: Max. value of single‑turn position exceeded in rotation mode
Cause:
The target position exceeds the upper/lower limit of the unit position in the single‑
turn absolute mode.
Cause
Confirming Method
Solution
The target position exceeds
the upper/lower limit of the
unit position in the single‑
turn absolute mode.
Check whether the set target
position is within the single‑
turn upper/lower limit.
Set the target position to a
value within the upper/
lower limit.
● EB02.0: Excessive position deviation in fully closed‑loop mode
Cause:
The absolute value of position deviation in fully closed‑loop mode exceeds the
value of H0F.08 (Excessive position deviation threshold in fully closed‑loop mode).
Cause
Confirming Method
Solution
1. U/V/W output phase loss
or incorrect phase sequence
occurs on the servo drive.
Perform a no‑load trial run
on the motor and check the
wiring.
Connect cables again
according to the correct
wiring diagram or replace
the cables.
2. The servo drive U/V/W
cables or the encoder cable
is disconnected.
Check the wiring.
Connect the cables again.
The servo drive power
cables must be connected in
the correct order at both
ends. Replace with new
cables if necessary and
ensure cables are connected
properly.
3. The motor is stalled due
to mechanical factors.
Check the reference and
motor speed (H0b.00)
through the software tool or
keypad.
References in the position
control mode: H0b.13 (Input
position reference counter)
References in the speed
control mode: H0b.01
(Speed reference)
References in the torque
control mode: H0b.02
(Internal torque reference)
Check whether the reference
value is not 0 but the motor
speed is 0 rpm in the
corresponding mode.
Eliminate the mechanical
factors.
