Inovance SV670P Series - Communication Cable Selection

Description of Fault Codes
‑36‑
Cause
Confirming Method
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
Cause:
The junction temperature parameter is identified incorrectly.
Cause
Confirming Method
Solution
Junction temperature
parameter CRC check failed
Check that the junction
temperature parameter is
present
Rewrite the junction
temperature parameter.
● E122.1: Different DIs allocated with the same function
Cause:
The same function is assigned to different DIs.
The DI function No. exceeds the maximum number allowed for DI functions.
Cause
Confirming Method
Solution
1. Multiple DIs are assigned
with the same function.
Check whether DI function
numbers set in group H03
are repetitive.
Change any repetitive
number.
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 the DO function
numbers defined by H04.00,
H04.02 and H04.04.
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.
