Cause
Confirming Method
Solution
The upper limit of the
mechanical single‑turn
position exceeds 2
31
.
Check the setting of the
mechanical gear ratio, the
upper limit of mechanical
single‑turn position and the
electronic gear ratio when
the servo drive runs in the
absolute rotation mode
(H02.01 = 2).
Reset the mechanical gear
ratio, the upper limit of
mechanical single‑turn
position and the electronic
gear ratio to ensure the
upper limit of the
mechanical single‑turn
position (reference range)
does not exceed 2
31
.
● E122.4: Different VDIs assigned with the same function
Cause:
The same function is assigned to different VDIs. The VDI function No. exceeds the
maximum number allowed for VDI functions.
Cause
Confirming Method
Solution
1. Two or more VDIs are
assigned with the same
function No.
Check whether DI function
numbers set in group H17
are repetitive.
Change any repetitive
number.
2. The VDI function No.
exceeds the maximum
number allowed for VDI
functions
Check whether the MCU
program is updated.
Restore system parameters
to default values (H02.31 =
1) and restart the servo
drive.
● E122.5: DI and VDI assigned with the same function
Cause:
The same function is assigned to different VDIs. The VDI function No. exceeds the
maximum number allowed for VDI functions.
Cause
Confirming Method
Solution
Two or more DIs and VDIs
are assigned with the same
function No.
Check whether DI function
numbers set in groups H03
and H17 are repetitive.
Assign different DI function
numbers to these
parameters, and then re‑
energize the control circuit
to activate the assignment,
or switch off the S‑ON signal
and send a "RESET" signal
to activate the assignment.
● E122.7: Fully closed‑loop parameter setting error
Cause:
Cause
Confirming Method
Solution
When H0F.00 is not 0, set
H02.01 to 2 (absolute
position rotation mode)
Check the value of H02.01 if
fully closed‑loop is used.
Set the value of H02.01 to 2
if fully closed‑loop is used.
E122.9: Fully closed‑loop function pin conflict
