Solution
The upper limit of the
mechanical single‑turn
position exceeds 2
31
in the
absolute position rotation
mode.
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
Description:
The same function is assigned to different VDIs. The VDI function No. exceeds the
maximum number allowed for VDI functions.
Cause
Troubleshooting
Solution
1. The same function is
assigned to different VDIs
Check whether parameters
in groups H03 (H03.02,
H03.04...H03.20) and H17
(H17.00, H17.02...H17.30) are
assigned with the same non‑
zero DI function No.
Assign different DI function
numbers to parameters in
groups H03 or H17, and then
restart the control circuit to
activate the assignment, or
switch off the S‑ON signal
and send a "RESET" signal
to activate the assignment.
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
Description:
The same function is assigned to different VDIs. The VDI function No. exceeds the
maximum number allowed for VDI functions.
Cause
Troubleshooting
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.
Change any repetitive
number.
● E122.8: small lower limit of the rotation mode
Description:
The lower limit of the mechanical single‑turn position is less than 1.
