Page 3: Introduction
SFU-0303 M a n u a l Introduction Due to its construction, the rotational speed of a 3-phase AC motor is directly dependent on the number of poles and the frequency of the network. In case of a 3PH 50Hz network and a 2-pole motor, the nominal speed would be 50 rps * 60 = 3000 rpm. - Page 4 SFU-0303 M a n u a l Several case options for cabinet mounting (SSE) , 19" rack style and desktop, or special designs on request User friendly Screw-plug connector system for power-, spindle- and I/O connectors. Wide range of operating voltage 115V-230V Automatic deceleration of the spindle down to standstill in case of mains failiure by "Back Energy"...
