BICO: Writing to parameter not permitted as the master control is active

¿Qué significa 201515 ?

This alarm occurs when an attempt is made to change the number of Command Data Sets (CDS) or copy from a CDS while the master control is still active. Parameters related to BICO (Bi-directional interconnection) configurations cannot be altered under these conditions to maintain system integrity. This is a functional restriction rather than a critical fault, typically requiring no immediate action as the system prevents an invalid operation.

• Attempting to change parameters related to Command Data Sets (CDS) or BICO interconnections (e.g., P0800, P0801) while the drive is enabled or running (master control active).
• Incorrect sequencing in the PLC program: trying to write configuration parameters before placing the drive into a disabled or parameterization-ready state (e.g., P0840=0).
• Drive operating in a safety-relevant mode (e.g., P9500 active) that prevents dynamic changes to control parameters.
• An external command (e.g., from a higher-level controller or HMI) is overriding local parameter changes.
• The 'master control' parameter (e.g., P0840) is configured to a source that is always active, preventing parameter changes.

1. 1

   1. Before attempting to modify BICO or CDS-related parameters, set the master control to OFF (e.g., P0840 = 0 from PLC or via operator panel).

2. 2

   2. Ensure the drive is in a safe, disabled state (e.g., main contactor open, STO active if applicable) before attempting parameter changes.

3. 3

   3. Sequence the PLC program to write these parameters only during initial commissioning or a controlled machine shutdown.

4. 4

   4. Check for any active safety functions (e.g., STO) that might be preventing parameter writes while active.

5. 5

   5. If using an engineering tool (e.g., TIA Portal), ensure online parameter changes are allowed, or perform an offline download.
