Description of Warning Codes
‑21‑
● E831.0: AI2 zero offset too large
Cause
Confirming Method Solution
1. The wiring is incorrect or
interference exists.
Check the wiring according
to the correct wiring
diagram.
Use shielded twisted pairs
and shorten the circuit
length. Increase AI2 input
filter time.
2. The servo drive is faulty.
Disconnect AI1 and measure
whether the actual terminal
voltage exceeds 0.5 V.
If not, replace the servo
drive.
● E834.2: AI2 overvoltage
Cause
Confirming Method Solution
1. The wiring is incorrect or
interference exists.
Check the wiring according
to the correct wiring
diagram.
Use shielded twisted pairs
and shorten the circuit
length. Increase AI2 input
filter time.
2. The input voltage is too
high.
Measure whether the actual
terminal voltage exceeds
11.5 V.
Adjust the input voltage to a
value lower than 11.5 V.
● E834.2: AI2 overcurrent
Cause
Confirming Method Solution
1. The wiring is incorrect or
interference exists.
Check the wiring according
to the correct wiring
diagram.
Use shielded twisted pairs
and shorten the circuit
length. Increase AI1 input
filter time.
2. The input current is too
large.
Check the value of H0b.22.
Adjust the input current to a
value lower than 21 mA.
● E900.0: DI emergency braking
Cause:
The logic of the DI terminal (including the hardware DI and virtual DI) allocated
with DI function 34 (FunIN.34) is effective.
Cause
Confirming Method
Solution
The DI function 34
(EmergencyStop) is
triggered.
Check whether the logic of
the DI assigned with
FunIN.34 (EmergencyStop) is
active.
Check the operation mode
and clear the active DI
braking signal without
affecting the safety
performance.
● E902.0: DI setting invalid
Cause:
DI function parameters are set to invalid values.
