Delta Electronics ASDA-AB manual Reverse limit switch error, Forward limit switch error

Chapter 5 Trial Run and Tuning ProcedureASDA-AB Series

„If it is necessary to use “Emergency Stop (EMGS)” as input signal, the users only need to confirm that which of digital inputs DI1~DI8 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~DI8 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~DI8 are not set to “Reverse inhibit limit (CWL)”. (The setting value of parameter P2-10 to P2-17 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~DI8 is set to “Reverse inhibit limit (CWL)” and check if the digital input signal is ON (It should be activated).

5)When display shows:

Forward limit switch error:

Please check if any of digital inputs DI1~DI8 signal is set to “Forward inhibit limit (CCWL)” and check if the signal is ON or not.

Corrective Actions:

„If it is no need to use “Forward inhibit limit (CCWL)” as input signal, the users only need to confirm that if all of the digital inputs DI1~DI8 are not set to “Forward inhibit limit (CCWL)”. (The setting value of parameter P2-10 to P2-17 is not set to 23.)

„If it is necessary to use “Forward inhibit limit (CCWL)” as input signal, the users only need to confirm that which of digital inputs DI1~DI8 is set to “Forward inhibit limit (CCWL)” and check if the digital input signal is ON (It should be activated).
