106 Unidrive SP Regen Installation Guide
www.controltechniques.com Issue Number: 2
The drive reactive current is shown in this parameter for all modes.
The current limit applied at any time depends on whether the drive is motoring or regenerating and also on the level of the symmetrical current limit.
Pr 4.18 gives the limit level that applies at any instant.
See Pr 4.16 on page 105.
This parameter displays the active current (Pr 4.02) as a percentage of the rated current (Pr 5.07 or Pr 21.07). Positive values indicate power flow
from the supply and negative values indicate power into the supply.
The maximum for Pr 4.08 and Pr 4.20 is defined by this parameter.
