What is R2 relay on the ATV28 and its specifications?

The R2A is a N/O pogrammable relay for the unit.

R2C is common.

The relay has a minimum switching capacity of
   - 10Ma for 5Vdc
                         maximum switching capacity on inductive load
   (cos theta = 0.4 and L/R = 7ms):
   - 1.5 a for 250Vac and 30Vdc

The relay can be assigned to:
  no: not assigned
  FtA: frequency threshold reached.  The contact is closed when the motor frequency is greater than or equal to the threshold se by Ftd (*)
  CtA: current threshold reached.  The contact is closed when the motor current is greater than or equal to the threshold set by Ctd (*)
  StA:  speed reference reached.  The contact is closed when the motor frequency is greater than or equal to the speed reference.
  tSA:  thermal threshold reached .  The contact is closed when the motor thermal state is greater than or equal to the threshold set by ttd. (*)

* (assigning this function displays the corresponding settings in the SEt- menu so that they can be adjusted.)
