Encoder Error; Emergency Stop Activated; Reverse Limit Switch Error - Delta Electronics ASDA-B Series User Manual

Chapter 5 Trial Run and Tuning Procedure|ASDA-B Series
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).
