Troubleshooting and Maintenance
Error No. 99.0
Error No. 99.0 may occur due to the timing between safety input 1/2 and error clear input.
This error will occur if both of the following conditions are met:
 An error was cleared when at least one of the input photocouplers for safety inputs 1 and 2 was
OFF (which means that a Safety Input Error (Error No. 30.0) had occurred).
 At least one of the input photocouplers for safety inputs 1 and 2 was turned from OFF to ON in a
specific period during the error clear process (See below).
*1 Error No. 99.0 will occur if at least one of the input photocouplers for safety inputs 1 and 2
is turned from OFF to ON.
Precautions for Correct Use
Be sure to clear the error after turning ON the photocouplers for safety inputs 1 and 2 again.
99 0
Other errors • An error signal was detected due to
excess noise or some other problem.
• An error was reset when safety input 1
or 2 was not in a normal state (one of the
input photocouplers is not ON).
• Turn OFF the power once, and turn it
ON again.
• If the error is displayed even after the
power is turned ON again, the system
may be faulty. Stop using the system,
and replace the Servomotor and/or the
Servo Drive. Return the Servo Drive to
the dealer that it was purchased from
and ask for investigation and repair.
• Reset the error when both safety input 1
and 2 are in a normal state (the both
input photocouplers are ON).
Other numbers
The control circuit malfunctioned due to
excess noise or some other problem. The
self-diagnosis function of the Servo Drive
was activated, and an error occurred in
the Servo Drive.
• Turn OFF the power once, and turn it
ON again.
• If the error is displayed even after the
power is turned ON again, the system
may be faulty. Stop using the system,
and replace the Servomotor and/or the
Servo Drive. Return the Servo Drive to
the dealer that it was purchased from
and ask for investigation and repair.
