The DC-link voltage Ripple is a crucial parameter in the functioning of a motor drive system. When this ripple exceeds the drive's capability to safely operate, an alarm is triggered. This alarm serves as an early warning sign, alerting operators to potential issues with the system.

The primary cause of this alarm is a blown input fuse to the drive. Input fuses are designed to protect the drive circuitry from damage caused by excessive current or voltage spikes. If an input fuse blows, it interrupts the power supply to the drive, potentially causing the DC-link voltage ripple to exceed safe limits.

When this alarm occurs, it is essential to immediately investigate the cause and take appropriate action. Failure to do so could result in further damage to the drive or even catastrophic failure of the entire system.

In addition to checking the input fuses, it is also recommended to inspect the power supply and other components of the drive system. Faulty power supplies or damaged wiring can also contribute to DC-link voltage ripple issues.
