Page 10: Introduction
Introduction This is the User’s Guide for Focus 3N (Non-regenerative) series of DC Drives. The Focus 3 is a 3rd generation product of the long-standing Focus series. The Focus 1 was introduced back in 1980 and the Focus 2 later in 1982. The Focus 2 was retired when the Focus 3 was introduced as it took advantage of many technological advances in power electronics. -
Page 11: Motor Compatibility
Motor Compatibility The Focus 3 was designed to run standard 90 Vdc or 180 Vdc Shunt Wound or Permanent Magnet DC motors in one direction. The Focus 3 can run motors with other characteristics (such as Universal motors) but one must review those requirements to insure compatibility. Universal motors have commutator brushes but typically plug into the AC power line. -

Page 13: Basic Control Modes/Feedback
Speed Control Armature Voltage Feedback The Focus 3 can vary the speed of the motors mentioned above as a function of the Speed potentiometer setting (or external speed command signal) by simply varying the output Armature voltage (field excitation if used typically remains constant). A great many motor applications do not require ultra precise speed control. -
Page 14: Receiving, Inspection, Storing
General Information Introduction The purpose of this manual is to provide the user with the information needed to install, start-up, and maintain the Focus 3 drive. This instruction manual should be read in its entirety, paying special attention to the warning and caution notices, before installation and before performing any start-up or drive maintenance. -

There are two basic methods used, the first is a parallel method and the second is a cascaded method. In the parallel method the speed command of the first drive is sent directly to the second drive (as a speed command) while in the cascaded method, the speed feedback (tachometer) is directed to the second drive as a speed command. - Page 73 Focus 3 Non-Regen Master / Follower Application Moto Motor Arma ture Armature Motor Thermal Motor Thermal FOCUS 3 FO US 3 Stop Stop Start Start Drive run enable Drive run enable Motor Field Motor F ield Regen egen Manual only Manual Auto Auto...
