NOTES:
•
It’s mandatory to use shielded cables and to connect shield to PE terminal both drive and motor side.
•
To ensure a correct electric wiring, and for electric safety, use an adequate cap.
•
For cable lenght longer than 50meters, it could be necessary to use a triphase motor choke to grant
drive correct operation.
•
It’s recommended to perform motor autophasing procedure to ensure that connection is correct (it’s
mandatory if third party motor is used). Please see
“6.07 Motor autophasing” pag. 82

For information about H.D.T. AC brushless motors wiring (serie B05-B26, BSD10-BSD14 e MS04-MS08),
refer to technical manuals downloaded from internet corporate site:
