EMC 10: Bad CC Encoder Error

The Bad CC Encoder error indicates that the EMC 10 is unable to properly communicate with or receive position information from the Color Change (CC) system. This can be caused by configuration issues, wiring problems, a faulty Color Change Board, or a problem with the 4-Axis PCB.

Verify Machine Configuration

Begin by confirming that the machine is configured correctly as an EMC 10.

Refer to the EMC 10 Operation Manual and follow the machine configuration procedure. An incorrect machine configuration can generate color change-related errors.

Check Color Index Alignment

A Bad CC Encoder error can sometimes be related to the same issues that cause an Off Color Index Error.

Verify that the needle case is properly indexed and review the troubleshooting procedures outlined in the Off Color Index section of the manual.

Inspect the Color Change Harness

Check the Color Change harness connections at both ends of the cable:

• At the rear of the Color Change PCB
• At the 4-Axis PCB

Ensure that all connectors are fully seated and free from damage.

A loose or disconnected harness can cause communication failures and may also generate a CC Command Error.

Inspect the Color Change Board

If the harness connections are secure, inspect the Color Change Board (CC Board) for signs of damage or failure.

In many cases, a defective Color Change Board can cause encoder communication errors and prevent proper needle case positioning.

Reseat the 4-Axis PCB

If the problem persists, power down the machine and reseat the 4-Axis PCB according to the procedures outlined in the EMC 10 Technical Manual.

Poor PCB connections can occasionally cause intermittent communication problems.

Replace the 4-Axis PCB

If all previous checks have been completed and the Bad CC Encoder error remains, the 4-Axis PCB may require replacement.

Summary

Common causes of a Bad CC Encoder error include:

• Incorrect EMC 10 configuration
• Off Color Index conditions
• Loose or damaged Color Change harness connections
• Faulty Color Change Board (CC Board)
• Poor 4-Axis PCB connection
• Failed 4-Axis PCB

Following these troubleshooting steps will resolve most Bad CC Encoder errors and restore proper color change operation on the EMC 10.
