SP MINI Stepper Motor Power Stage with Supply Unit for 230VAC SP MINI Power Stages Application Ranges The compact stepper motor power stages including supply unit are directly connected to the mains voltage 230 VAC (option: 115 VAC). The phytron SP MINI stepper motor power stages are used for positioning by PC and SPS controllers, e. g. in apparatus engineering or in application technology. SP MINI are available with 5, 7 or 9 APEAK maximum phase current. The step resolution can be set by rotary switches from full step to 1/5 step. Control signals for SP MINI can be supplied by controllers with step pulses ±direction signals or PC with stepper motor interface. Mounting brackets allow to mount the flat SP MINI housing alternatively vertical or horizontal in a switch cabinet depending on the allocated space. Maximum use of the motor torque and a smooth stepper motor drive result from the rotating field synchronized current regulation based on the patented SYNCHROCHOP principle. Technical Information The CE-conform device design meets the requirements of the EU directives when mounted EMC compliant. Optimum noise suppression between control and power circuit is obtained by optocouplers for electrical insulation of the push-pull inputs from the supply voltage.

Hmensions / Inputs / Error Output / Motor Brake / Ordering Code The push-pull inputs - Control pulses, Motor direction, Deactivation, Reset, Boost and Brake - are electrically insulated from the power stage supply voltage by optocouplers. That way, an optimum noise suppression is achieved between control and power circuit. High immunity is obtained when driving the SP MINI with RS422-push-pull signals (fig. 3), because the lines are permanently supplied. Alternatively, an open collector controlling is also possible - see in manual SP MINI. The standard logic voltage is +5 V, which can be...
