Delta Electronics ASDA-B Series manual Encoder error, Emergency stop activated

Chapter 5 Trial Run and Tuning ProcedureASDA-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).
