CdE Code Error (SoftPLC) fault in delta drive

CdE Code Error (SoftPLC) fault in delta drive troubleshooting

Description

Modern Delta drives (like C2000 Plus) have a built-in PLC (Programmable Logic Controller). CdE indicates that the PLC program running in the background has crashed, encountered an infinite loop, or is corrupted.

Causes

1. Corrupt Program: The WPLSoft or ISPSoft program uploaded to the drive was interrupted during download.
2. Logic Error: The PLC code contains a mathematical error (e.g., dividing by zero) or an infinite "While" loop that freezes the processor.
3. Resource Overflow: The program is trying to access registers or memory addresses that do not exist.

Solution

Software reset:
1. Disable PLC: Set Parameter 00-02 (or PLC function parameter) to "Stop PLC" or "Disable". Reboot the drive.
2. Re-download: Connect your PC, re-compile the PLC program, and download it again to the drive.
3. Check Logic: Review your ladder logic for errors.
4. Factory Reset: If the drive is stuck, perform a factory reset to wipe the PLC memory.
