For drives equipped with an internal Regeneration resistor, the parameters associated with that resistor are set
automatically. If the drive has external regeneration capability only, all regeneration resistor parameters are set to zero.
In this case, the drive will display a fault (F3) and will not enable until suitable parameters for the external regeneration
resistors are entered and saved. The resistance and power rating of the external regeneration resistor connected to the
drive should be entered in the “External Regen” window.
 Open “Drive Setup
→ Regen Resistor → External Regen” and enter the correct resistance and power ratings for the
externally connected Regen Resistor (RR).
 Select Write All.
 Confirm that values are correct.
Figure 4.10 External Regen Parameters
The software also checks the value of regeneration resistance entered. If too low a value is entered, such that the current
that would flow on turn-on of the regeneration transistor exceeds the ratings of the regeneration, transistor, a fault (F3) is
also reported.
The drive will also display an F3 if the user inputs data for a regeneration resistor such that the current, which would
flow in the regeneration transistor on turn on, is greater than the Max RR Current level set in the GUI panels “DS2100
