Stepper motor power stage for bipolar control The MSX is a power stage for bipolar control of 2 phase stepper motors. The power stage is available in three power ranges with 15 APEAK maximum phase current. The current regulation by the patented SYNCHROCHOP principle ensures a smooth operation of the stepper motor and the torque for optimum use. Besides full and half step the MSX provides a resolution up to 1/20 MINI Step. The MSX is suitable to replace the well-tried older phytron power stages MSO, MSO and SMD. The setting switch provides several phase current profile settings: • full step (conventional) • half step - without / with torque compensation - without / with Current Shaping • 1/4 - 1/20 step - without / with Current Shaping - with Current Shaping and BLOW UP. Application As a powerful stepper motor power stage the MSX is suitable for up to 800 Watts shaft power, especially for the handling of discrete components and machine service tasks as well as for high-throughput sorting and assembly machinery. Highlights Current Shaping • Stepper motor power stage for bipolar control of 2 phase stepper motors • up to 15 APEAK phase current • Supply voltage 60 to 120 VDC (permissible range 40 to 160 VDC) • DIP switches for Overdrive and Boost functions, Activation and Preferential Motor Direction • Step resolution from full step to 1/20 step The CS (Curent Shaping) function allows adapting the actual current shape to the selected current curve over a wide frequency range. Improvement of run and acceleration behaviour can be achieved - dependent on the motor type - by the current shape optimising BLOW UP function.
