A.E4 MDT Loss • Fiber optics are cut.
• Servo board is defective.
• SERCOS IF is defective.
• Manually readjust the fiber
optics cabling.
• Replace the Servopack.
• Replace the SERCOS IF.
• Check if the fiber optics connector
is detached or if the connection is
cut.
• Check for alarms such as cuts in
servo board communications.

initialization of the
SERCOS communications.
NP1MT009E
A.E7 SERCOS IF Error • Occurs at power ON. • SERCOS IF is not connected
correctly.
• SERCOS IF is defective.
• Check that the connector
between the SGDH and the
SERCOS IF is connected properly.
• SERCOS IF is defective.
(DPRAM is defective).

CPF00
CPF01
Digital Operator
Transmission Error 1
Transmission Error 2
• Occurs at power ON when
the digital operator is connected
or when the digital operator is
connected after power ON.
(Whether transmission is
established is determined by
checking the data code of the
signal that is sent every approx.
100 msec from the Servopack.
If the data code is normal,
transmission is established.)
• Imperfect connection between
the digital operator and
Servopack.
• Digital operator defective.
• Servopack defective.
• Incorrect cable or connection
between the digital operator and
Servopack.
• Digital operator control defective.
• Servopack defective.
• Insert the connector again or
replace the cable.
• Replace the digital operator.
• Replace the Servopack.
