Regenerative Brake Pre-alarm

What does Regenerative brake pre-alarm mean?

The regenerative brake duty has reached 85% or higher of the Pr. 70 Special regenerative brake duty setting. This warning indicates that the regenerative braking capacity is approaching its limit. If deceleration demands continue to be high without sufficient energy dissipation (e.g., a braking resistor), it could lead to an overvoltage fault.
