2) When display shows:
Encoder error:
Check if the wiring is correct. Check if the encoder wiring (CN2) of servo motor is loose or incorrect.
Corrective Actions:
„ Check if the user performs wiring recommended in the user manual.
„ Examine the encoder connector and cable.
„ Inspect whether wire is loose or not.
„ Check if the encoder is damaged.
3) When display shows:
Emergency stop activated:
Please check if any of digital inputs DI1~DI6 signal is set to “Emergency Stop” (EMGS).
Corrective Actions:
„ If it does not need to use “Emergency Stop (EMGS)” as input signal, the users only need to
confirm that if all of the digital inputs DI1~DI6 are not set to “Emergency Stop (EMGS)”. (The
setting value of parameter P2-10 to P2-15 is not set to 21.)
„ If it is necessary to use “Emergency Stop (EMGS)” as input signal, the users only need to
confirm that which of digital inputs DI1~DI6 is set to “Emergency Stop (EMGS)” and check if
the digital input signal is ON (It should be activated).
4) When display shows:
Reverse limit switch error:
Please check if any of digital inputs DI1~DI6 signal is set to “Reverse inhibit limit (CWL)” and check if
the signal is ON or not.
Corrective Actions:
„ If it does not need to use “Reverse inhibit limit (CWL)” as input signal, the users only need to
confirm that if all of the digital inputs DI1~DI6 are not set to “Reverse inhibit limit (CWL)”. (The
setting value of parameter P2-10 to P2-15 is not set to 22.)
„ If it is necessary to use “Reverse inhibit limit (CWL)” as input signal, the users only need to
confirm that which of digital inputs DI1~DI6 is set to “Reverse inhibit limit (CWL)” and check if
the digital input signal is ON (It should be activated).
