MSD MINI Stepper Motor Power Stage with Supply Unit for Rack or Wall Mounting Technical Information Ministep power stage for controlling 2-phase stepper motors Supply unit for direct connection to 230 VAC (optional: 115 VAC) Phase currents up to 17 APEAK 2 models with different motor voltage: MSD MINI 172-70: 70 V or MSD MINI 172-140: 140 V Step resolutions: from full step to 1/20 step Maximum torque utilization by Boost and Overdrive Rotary switches for setting Run, Boost and Stop current, Step resolution and Preferential motor direction Electrical separation of inputs and outputs by optocouplers Electronical monitoring of overtemperature, short-circuit and low voltage Status LED 2 models with different design: Rack or wall mounting Optional: connection of stepper motor with permanent magnet motor brake EMC-compliant design MSD / 07-2 GB The compact stepper motor power stages include a supply unit for direct connection to 230 VAC (optional 115 VAC). MSD MINI are available in 4 models with different motor voltage and design: 70 or 140 VDC motor voltage Housing with 6 U front plate for mounting in 19" racks or housing with removable mounting brackets for wall mounting. The phase currents up to 17 APEAK and the step resolution (full step to 1/20 step) are selectable by setting switches. Optimum motor drive and best use of the motor torque are achieved by the rotating field synchronized current regulation based on the patented SYNCHROCHOP principle as well as by the overdrive and boost functions. MSD MINI Power Stages Application Ranges Power Stages phytron MSD MINI stepper motor power stages are preferentially used for positioning tasks with programmable systems like PLC: in machine and appliance construction, handling systems, labelling and packaging machines. MSD MINI control signals may be provided from control units delivering step pulses and direction signals or from PCs equipped with a stepper motor interface. Noise suppression between control and power circuit is obtained by optocouplers for electrical separation of the push-pull inputs from the supply voltage. MSD MINI power stages with supply unit meet the requirements of the EMC and Low Voltage EU Directives and therefore, may bear the CE mark. The units do not require additional external filters for EMC-correct wiring. Control Elements Stepper motor connection I/O Signal connector Setting switches Status LED Cable clamps for shield connection and strain relief PE connection Optional motor brake connection Fuse Mains 230VAC (Optional 115 VAC) Boost current Run current Stop current Step resolution and preferential motor direction Fig. 1

Wall Mounting / Rack Mounting / Motor Brake / Ordering Code Ordering Code MSD MINI 172-140-W-115 V Type Peak current Current regulation Motor voltage Mounting Optional MSD MINI 17 2 70 140 WR 115 OK Optional: Motor Brake MSD MINI supports the operation of stepper motors with a 24 VDC / 1 A max. permanent magnet motor brake. The braking effect of the motor brake is controlled via the Brake input (I/O connector). If this input is activated, the brake is supplied with current and the braking effect is suppressed. If an error signal occurs or the Deactivation input is active, the brake supply...
