A.E72 Feedback Option Module Detection Failure The connection between the SERVOPACK and the Feedback Option Module is Faulty. Check the connection between the SERVOPACK and the Feedback Option Module. Correctly connect the Feedback Option Module. The Feedback Option Module was disconnected. — Execute resetting configuration error in option modules (Fn014) and turn the power supply OFF and then ON again. A Feedback Option Module fault occurred. — Replace the Feedback Option Module. A SERVOPACK fault occurred. — Replace the SERVOPACK. A.Eb1 Safety Function Signal Input Timing Error The lag between activations of the input signals /HWBB1 and /HWBB2 for the HWBB function is ten second or more. Measure the time lag between the /HWBB1 and /HWBB2 signals. The output signal circuits or devices for /HWBB1 and /HWBB2 or the SERVOPACK input signal circuits may be faulty. Alternatively, the input signal cables may be disconnected. Check if any of these items are faulty or have been disconnected. A.F10 Main Circuit Cable Open Phase
(With the main power supply ON, voltage was low for more than 1 second in an R, S, or T phase.)
(Detected when the main power supply was turned ON.) The three-phase power supply wiring is incorrect. Check the power supply wiring. Confirm that the power supply is correctly wired. The three-phase power supply is unbalanced. Measure the voltage at each phase of the three-phase power supply. Balance the power supply by changing phases. A single-phase power is input without setting Pn00B.2 (power supply method for three-phase SERVOPACK) to 1 (single-phase power supply). Check the power supply and the parameter setting. Match the parameter setting to the power supply. A SERVOPACK fault occurred. — Turn the power supply OFF and then ON again. If the alarm still occurs, the SERVOPACK may be faulty. Replace the SERVOPACK. CPF00 Digital Operator Transmission Error 1 The contact between the digital operator and the SERVOPACK is faulty. Check the connector contact. Insert securely the connector or replace the cable. Malfunction caused by noise interference. — Keep the digital operator or the cable away from noise sources. CPF01 Digital Operator Transmission Error 2 A digital operator fault occurred. — Disconnect the digital operator and then re-connect it. If the alarm still occurs, the digital operator may be faulty. Replace the digital operator. A SERVOPACK fault occurred. — Turn the power supply OFF and then ON again. If the alarm still occurs, the SERVOPACK may be faulty. Replace the SERVOPACK.
