If a fault is detected on the servo drive or motor a corresponding fault code will be shown on
the drive's LED display. Fault codes can also be transmitted via communication, see P0-01 and
P4-00 ~ P4-04 for display on controller or HMI.

Questions and answers
How can l run the command input correctly
To run the command input correctly for the Delta ASDA-B2-0121-B servo drive, follow these steps:
1. Ensure Proper Wiring: Do not change wiring while the power is connected. Verify all connections are secure.
2. Enable Emergency Stop: Ensure the emergency stop function is available before powering on.
3. Set Parameter P3-06: This determines how digital inputs (DI) accept commands, either through an external terminal or communication, as determined by P4-07.
4. Configure Digital Inputs: Set parameters P2-11 (DI2), P2-12 (DI3), and P2-13 (DI4) as needed for functional planning.
5. Check for Faults: If an error occurs (e.g., E0001), check the ROM data and contact Delta support if necessary.
6. Review Encoder and Output Pulse Settings: Ensure P1-76 and P1-46 are correctly set to avoid abnormal signal output.
7. Verify Serial Communication: Ensure proper settings to avoid communication errors.
Following these steps will help ensure the correct operation of the command input.
