Inovance / F09
Series: HD5X
User high-voltage power supply undervoltage
AC drive
Meaning: 1.Unit detection is complete during operation, and high voltage is lost2.During automatic restart after power restoration, the high-voltage input is absent and a unit fault/unit undervoltage/unit drive fault occurs
Possible causes
- 1.Loss of high-voltage power during operation
- 2.Three-phase input voltage sampling resistor error
- 3.AC drive input voltage sampling circuit error
- 4.AC drive input voltage outside the specified range
- 5.Input main circuit error
- 6.Control hardware error
