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).

Servo Drive. Return the Servo Drive to
the dealer that it was purchased from
and ask for investigation and repair.
