Description of Fault Codes
‑37‑
Cause
Confirming Method
Solution
1. Multiple DIs are assigned
with the same function.
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 DI function No.
exceeds the maximum
number allowed for DI
functions
Check whether the MCU
program is updated.
Restore system parameters
to default values (H02.31 =
1) and restart the servo
drive.
● E122.2: Different DOs assigned with the same function
Cause
Confirming Method
Solution
The DO function No. exceeds
the maximum number
allowed for DO functions
Check whether DO function
numbers defined by H04.00
and H04.02 are abnormal.
Set the correct DO function
No.
● E122.3: Upper limit in the rotation mode invalid
Cause:
The upper limit (reference range) of the mechanical single‑turn position exceeds
2
31
in the absolute position rotation mode.
Cause
Confirming Method
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
Cause:
The same function is assigned to different VDIs. The VDI function No. exceeds the
maximum number allowed for VDI functions.
