Control Voltage Error

What does S-0-0011 Bit 4 mean?

A Class 1 Diagnostic indicating an issue with the DDS 2.1 drive's internal control voltage supply. This often means that one or more internal low-voltage DC supplies (e.g., 24V, 5V) required for the control electronics are out of tolerance or absent, leading to a drive shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.

• Internal power supply fault within the DDS 2.1 drive.
• Instability or loss of the external 24VDC supply connected to the drive's control terminals (if applicable).
• Excessive load on auxiliary outputs supplied by the drive's internal control voltage.
• Faulty wiring or poor connection to the control voltage input terminals.
• Damaged control board components affecting voltage regulation.

Click steps to track your progress.

1. 1

   Measure the external 24VDC control supply voltage at the drive's input terminals to confirm it is stable and within specification.

2. 2

   Inspect control wiring and connections to the DDS 2.1 for loose terminals, damage, or corrosion.

3. 3

   Disconnect non-essential auxiliary loads powered by the drive's control voltage to check if the error clears.

4. 4

   Check the diagnostic LEDs or display on the DDS 2.1 for more specific indicators of internal power supply issues.

5. 5

   If no external causes are found, internal drive component failure is likely, requiring professional diagnosis or replacement.
