Description of Fault Codes

Cause
Confirming Method
Solution
1. The same function is
assigned to different VDIs
Check whether H03.02,
H03.04...H03.20 and H17.00,
H17.02...H17.30 are set with
the same non‑zero DI
function No.
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.
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.
Change any repetitive
number.
● 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
Cause:
The frequency division output pin conflicts with the fully closed loop second
encoder pin.
Cause
Confirming Method
Solution
The frequency division
output pin conflicts with the
fully closed loop second
encoder pin.
Check the setpoint of H05.38
and H0F.03.
Disable frequency‑division
output.
● E136.0: Encoder ROM motor parameter check error
Cause:
When reading parameters in the encoder ROM, the servo drive detects that no
parameters are saved there or parameter values are inconsistent with the
setpoints.
