System Fault
Vacon · X4
¿Qué significa 1 ?
This fault indicates an internal microprocessor problem (sub-codes 0, 1, 2) or an incorrect thermistor profile (sub-code 3). These issues point to a fundamental problem with the drive's internal control system that cannot be resolved through basic troubleshooting. The drive requires specialized attention.
Causas comunes
- Internal control board hardware malfunction (e.g., ASIC failure, memory corruption).
- Processor watchdog timer expiry due to software execution deadlock.
- Incorrect thermistor type or profile selected in parameter P0-15 (Thermistor Type) causing invalid temperature readings.
- Damage to control board components from electrical transients or environmental stress (e.g., extreme heat, vibration).
- Firmware corruption during update process leading to improper initialization.

- 1
1. Record the sub-code displayed on the drive's HMI or through diagnostic software.
- 2
2. Verify parameter P0-15 (Thermistor Type) matches the connected thermistor's specifications.
- 3
3. Perform a factory reset via parameter P0-01 (Parameter Reset) to restore default settings and re-enter required parameters.
- 4
4. Measure the supply voltage at the drive's input terminals (L1, L2, L3) to confirm it is within specified tolerance (e.g., 400V +/-10%).

5. Replace the control board or the entire drive unit if the fault persists after software and basic power checks.
