PLUSB3

~~ee~~ 

- = INTRODUCTION oS 5 = Stepping motor drives series with Step & = Direction interface suitable for driving two ~~a~~ phase stepping motors, with four, six or eight a terminals based on the following versions: Tr ~~-~~ PLUS A3 and PLUS A4: with DC power Fr supply (39-140 V,,) - PLUS B3, PLUS B4 and PLUS B7: with AC power supply (28 ~~-~~ 100 V,,) 

   - = Compact, easy to use and cost effective solution. This system is designed for mounting inside a metallic electrical cabinet. Suitable for wall mounting. 

   - = Target: medium. and medium-: ~~h~~ igh. power applications requiring great dynamic performance, high reliability, low acoustic noise and mechanic vibrations reduction. 

= Microstepping function up to 4.000 step/rev. 

- @ Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed. 

- ™ External fans not needed: ideal both for mounting inside a metallic electrical cabinet 

- @ and for stan ~~d-~~ alone ~~P~~ P applications. Operation with built ~~-~~ in oscillator with speed range from 14 to 450 rpm setting by means of dip ~~-~~ switches.
