Stepper Motor Power Stage MSX MINI - PHYTRON - #1

Text version of the page

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 5, 10 or 15 APEAK maximum phase current. Besides full and half step the MSX provides a resolution up to 1/20 MINI Step. 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. The current regulation by the patented SYNCHROCHOP principle ensures a smooth operation of the stepper motor and the torque for optimum use. The MSX is suitable to replace the well-tried older phytron power stages MSO, MSO and SMD. 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. MSX Stepper Motor Power Stage for Bipolar Control Current Shaping The CS (Curent Shaping) function allows adapting the actual current shape to the selected current curve over a wide frequency range. BLOW UP Improvement of run and acceleration behaviour can be achieved - dependent on the motor type - by the current shape optimising BLOW UP function. without BLOW UP with BLOW UP .. 2..a +Iph -Iph BLOW UP Current Profile Improvement Highlights with CS without CS .. 2..a +Iph -Iph Current Shaping El.
