Description of Warning Codes
‑29‑
Cause
Confirming Method
Solution
1. The logic of the DI
assigned with FunIN.14 (P‑
OT function 14, positive limit
switch) is effective.
● Check whether a certain DI
in group H03 is assigned
with FunIN.14.
● Check whether the logic of
DI corresponding to the bit
of H0b.03 (Monitored DI
status) is effective.
Check the operation mode
and on the prerequisite of
ensuring safety, send a
reverse run command or
rotate the motor to
deactivate the logic of the DI
assigned with FunIN.14.
2. The servo position
feedback reaches the
positive software position
limit.
Check whether the position
feedback (H0b.17) is close to
the value of H0A.41.
Check whether the software
position limit is set in
H0A.40.
Ensure the servo drive
references are proper,
allowing the load travel
range to be within the
software position limit.
● E952.0: Reverse overtravel warning
Cause:
The logic of the DI terminal allocated with DI function 15 (FunIN.15: N‑OT, negative
limit switch) is effective.
Cause
Confirming Method
Solution
1. The logic of the DI
assigned with FunIN.15 is
effective.
● Check whether a certain DI
in group H03 is assigned
with FunIN.15.
● Check whether the logic of
DI corresponding to the bit
of H0b.03 (Monitored DI
status) is effective.
Check the operation mode.
On the prerequisite of
ensuring safety, send a
forward run command or
rotate the motor to
deactivate the logic of DI
assigned with FunIN.15.
2. The servo position
feedback reaches the
negative software position
limit.
Check whether the position
feedback (H0b.17) is close to
the value of H0A.43.
Check whether the software
position limit is set in
H0A.40.
Ensure the servo drive
references are proper,
allowing the load travel
range to be within the
software position limit.
● E954.0: Position command overflow
Cause
Confirming Method
Solution
in PR mode, the position
command is beyond the
limit.
1. Check the position
command.
2: Check the limit value.
Change the value of the
position command and the
limit.
● E971.0: Undervoltage warning for voltage drop protection
Cause
Confirming Method
Solution
The bus voltage is lower
than the undervoltage
threshold.
Check the bus voltage. Check the power supply.
● E980.0: Encoder algorithm error
