Description of Fault Codes
‑32‑
The servo drive model parameter cannot be identified.
Cause
Troubleshooting
Solution
Model parameter CRC check
failed
Check that the model
parameter is present.
Write the model parameter
again.
● E120.8: Junction temperature parameter check error
Description:
The junction temperature parameter is identified incorrectly.
Cause
Troubleshooting
Solution
Junction temperature
parameter CRC check failed
Check that the junction
temperature parameter is
present.
Rewrite the junction
temperature parameter.
● E122.1: Different DIs assigned with the same function
Description:
The same function is assigned to different DIs.
The DI function No. exceeds the maximum number allowed for DI functions.
Cause
Troubleshooting
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
Troubleshooting
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
Description:
The upper limit (reference range) of the mechanical single‑turn position exceeds
2
31
in the absolute position rotation mode.
