Danfoss VLT Programming Guide

2-16 AC brake Max. Current
Range: Function:
100.0 %* [Application dependant] Enter the maximum permissible current when using AC brake to avoid overheating of motor wind-
ings. The AC brake function is available in Flux mode only (FC 302 only).
2-17 Over-voltage Control
Option: Function:
Over-voltage control (OVC) reduces the risk of the frequency converter tripping due to an over
voltage on the DC link caused by generative power from the load.
[0] Disabled No OVC required.
[2] * Enabled Activates OVC.
NB!
The ramp time is automatically adjusted to avoid tripping of the frequency converter.
