Line voltage fault
Indramat · CLM01.3-M Flying Cutoff Control
¿Qué significa F383 ?
With HVR power supply units only! The mains voltage exceeds permissible tolerances of 3x 380...480V, ± 10%. This fault occurs when the incoming supply voltage is outside the acceptable operating range for the Indramat HVR power supply unit.
Causas comunes
- Mains voltage exceeds permissible tolerance (3x 380...480V, ± 10%) at the HVR power supply unit input.

- 1
Measure the incoming line voltage (phase-to-phase) at the input terminals of the Indramat HVR power supply unit (X1/L1, X1/L2, X1/L3).
- 2
Verify the measured voltage is consistently within the specified range of 3x 380...480V, ± 10%.
- 3
If the voltage is outside the range, check the upstream power distribution system for issues or ensure a correctly sized and configured matching transformer is used.
- 4
Consult the power utility if persistent voltage fluctuations or incorrect supply levels are detected on the main supply.
