24 V supply error

SEW Eurodrive · Drives

What does 15 mean?

The 24 VDC supply voltage, which powers the MOVIMOT drive's control electronics, is faulty or missing. This is a critical voltage for the internal logic and communication.

Common Causes

  • Missing 24 VDC supply voltage
  • Unstable or out-of-tolerance 24 VDC supply voltage
  • Faulty external 24 VDC power supply

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Measure the 24 VDC supply voltage at the MOVIMOT drive's input terminals (e.g., X10 terminals 1 and 2) and compare against the nominal value.

  2. 2

    Verify the operational status and output voltage of the external 24 VDC power supply unit (PSU).

  3. 3

    Inspect the 24 VDC supply cabling from the PSU to the MOVIMOT drive for loose connections, damage, or insulation faults.

  4. 4

    Check for any external loads or devices connected to the 24 VDC circuit that might be causing an overload or short circuit condition.
