Overvoltage

Was bedeutet 2 ?

A hardware trip (S1) has detected the DC-link voltage exceeding its safe limits. This can be caused by a deceleration time that is too short, high voltage spikes on the input power supply, or a rapid Start/Stop sequence. Subcode S2 indicates issues with overvoltage control supervision.

• Input voltage exceeds the maximum allowable limit (e.g., P1-12 > 480V).
• Power surge from the electrical grid.
• Faulty power supply unit generating excessive voltage.

1. 1

   Increase the deceleration time parameter in the drive settings to allow for slower motor braking.

2. 2

   If regenerative energy is an issue, consider installing an optional brake chopper and brake resistor system.

3. 3

   Activate or verify the settings of the drive's internal overvoltage controller.

4. 4

   Measure the input voltage at the drive's main power terminals to ensure it is within specified limits and stable.
