SP MINI Stepper Motor Power Stage with Supply Unit for 230VAC Technical Information Ministep stepper motor power stage Supply unit for direct connection to the mains voltage 230 VAC Option: 115 VAC Control of two-phase stepper motors 3 versions with the following phase currents: SP MINI 92-70 max. 9 APEAK SP MINI 72-70 max. 7 APEAK SP MINI 52-70 max. 5 APEAK Motor voltage: 70 V Step resolution: Full step to 1/5 step Rotary switches for setting the run current, step resolution, pref. motor direction and logic of the input signals Electrical insulation of inputs and error output by optocoupler Electronic monitoring of overheating, short circuit and undervoltage Optional connection of stepper motor with permanent magnet motor brake Compact design for wall mounting Variable mounting position EMC compliant design SP MINI / 07-1 GB The compact stepper motor power stages including supply unit are directly connected to the mains voltage 230 VAC (option: 115 VAC). 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. 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. Optimum noise suppression between control and power circuit is obtained by optocouplers for electrical insulation of the push-pull inputs from the supply voltage. SP MINI Power Stages Power Stages Application Ranges 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. 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. The CE-conform device design meets the requirements of the EU directives when mounted EMC compliant.
