Advantage
The available built-in encoders for the DR.. motors 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 additional space as it is the case with add-on speed sensors*.
MOVITRAC
®
standard inverter in combination with the “simple positioning” application module can
replace applications that, up to now, have been realized with creep/rapid speed switch-over with
initiator evaluation.
