Solution for RDC6612U Controller Intershift Head Unable to Perform Operations

To address the issue of the RDC6612U controller's inter head being unable to perform operations, the following steps can be taken to systematically troubleshoot:

1. Check the Enable Status and Signal State of Each Axis
First, confirm that each motion axis of the ganged head (such as the X and Y axes) is properly enabled. Access the controller's I/O monitoring or drive status interface to observe whether each axis driver is in a "Ready" state and if there are any alarm signals. If a certain axis is not enabled or the driver reports an error, the ganged head will be unable to perform coordinated operations due to safety locks. You will need to reset the driver or check if the corresponding emergency stop or limit switch signals have been triggered.

2. Confirm the Correct Processing Array Mode
Be sure to check the array method of the graphics in the file. If a solid-line array is used (i.e., graphics are connected by actual line segments), the ganged head will not work — because the controller will recognize the entire drawing as one complex, continuous path, rather than multiple independent processing units. To activate the ganged head, you must use a virtual array (also known as array copy or matrix copy) to ensure the graphics are independent individuals. During operation, after selecting the graphics in RDWorks software, you should generate the layout using the "Array Copy" function and confirm that the output processing path does not contain connecting lines.

3. Recheck Hardware Connections and Parameter Configurations
Inspect the communication cables between the ganged head and the controller for looseness or damage, especially the cables in the cable carrier that are prone to wear during high-frequency movement. Simultaneously, access the controller parameters to verify that the working mode of the ganged head (e.g., "Head 1 + Head 2 Alternating/Synchronous") matches the actual hardware configuration, and ensure that the spacing parameters between each head have been accurately entered.
