One ATV 320 Two motors

[StuartR2D2]

How do I wire this up?  One ATV 320 to two motors… does Schneider sell a duo terminal block to wire two motors to one drive? 

how do I wire in the seperate overloads?

In case of application with two motors in paralell connected to one drive, there are some constraints.

Consider the sum of motor current and also the sum of motor cable (to determine the eventual need of filters).

Be aware that motor will always run at same speed.

Thermically prodect the motors independantly. (additionnal device).

Another is on the settings, do not perform autotuning and set motor control law  (motor control type Ctt = Std), could also have a look on setting uFr, 

All information available in the ATV320 programming manual, Have a look under this text.

Schneider offers the LRD series overload relays which can be mounted directly to LC1D contactor series, or as a standalone overload using the base part # LA7DB106.  You would have to wire to the overloads separately then into the drive.  Or there is also some Power distribution blocks available.  

Here is a link to the overload catalog from www.se.com
