Issue: What is R2 relay on the ATV28 and its specifications?
Product Line: ATV28
Environment: All
Cause: N/A
Resolution: 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.)
