Non-volatile
Memory Data
Error
An error of data saved
in the non-volatile mem-
ory was detected.
Power interruption or
noise occurred while
parameters other than
the safety were saved
Save data after setting the parame-
ter again, and cycle the power sup-
ply.
Power interruption or
noise occurred while the
motor identity informa-
tion was saved
Execute Motor Setup, and cycle the
power supply.
Power interruption or
noise occurred while
safety parameters were
saved
Clear the FSoE slave address, exe-

Non-volatile
Memory
Hardware
Error
An error occurred on the
non-volatile memory.
False detection due to a
data read error that was
caused by excessive
noise
After you cycled the power supply, if
this error occurs continuously
although the error is reset, the
non-volatile memory is faulty.
Replace the Servo Drive.

Drive Prohibi-
tion Input
Error
Both the Positive Drive
Prohibition (POT) and
the Negative Drive Pro-
hibition Input (NOT)
turned ON.
An error occurred on the
switch, wire, power sup-
ply, and wiring that was
connected to the Posi-
tive Drive Prohibition
Input (POT) or Nega-
tive Drive Prohibition
Input (NOT).
Check and correct an error on the
switch, wire, power supply, and wir-
ing that is connected to the Positive
Drive Prohibition Input or Negative
Drive Prohibition Input.
False detection
occurred because the
control signal power
supply was turned ON
slowly.
Check whether the control signal
power supply (12 to 24 VDC) is
turned ON slowly, and adjust the
timing if it is slow.

Drive Prohibi-
tion Detected
The operation was
stopped according to
the user setting
because the motor ran
in the prohibited direc-
tion when the Drive Pro-
hibition was enabled.
Incorrect or broken wir-
ing of Positive Drive
Prohibition Input (POT)
or Negative Drive Prohi-
bition Input (NOT)
Correct the wiring if the Positive
Drive Prohibition Input (POT) or
Negative Drive Prohibition Input
(NOT) is wired incorrectly.
If the cable is broken, replace it.
Incorrect setting of the
Drive Prohibition Input
Review the setting of the drive pro-
hibition input port and set it cor-
rectly.

exceed the maximum number of
rotations.
