Advantage
The available built-in encoder for the DR.. motor series that can be installed on the B-side between
endshield and fan wheel are unique. With this solution the user does not have to provide for addi-
tional space as it is the case with add-on speed sensors.
The MOVITRAC
®
standard inverter from SEW-EURODRIVE in combination with the "simple position-
ing" application module can replace applications that, up to now, have been realized with creep/
rapid speed switch-over with initiator evaluation.
