3.5 Amp Bi-polar stepper motor drive MSE570 Evo 2

The MSE570 is a low cost high performance Eurocard Bi-polar drive designed for mounting in 3U high Euro-racks. Ideally suited for use with Nema size 17, 23 & 34 stepper motors, the unit provides a wide range of current options. Designed for use by original equipment manufacturers, the unit provides a reliable and economic in-service proven’ drive solution. Furthermore, the MSE570 design enables users to customise the unit to meet their exact requirements by providing a series of up-grade options which can easily be implemented. Improved Output stage efficiency The MSE570 Evo 2 features a chopped c onstant current output stage with on-board current settings fr om 0.5 to 3.5 Amps per phase to meet the requirements of virtually any 2 or 4 phase hybrid stepper motor in the Nema 17, 23 & 34 frame sizes. The use of chopped constant current drive techni ques combined with the latest developments in power stage technology results in significant advances in efficiency. Furthermore, the output current may be reduced via an external input when the motor is at standstill to reduce temperature rise in the dr ive and the motor. The drive is designed for use with rail voltages from 15 to 48 Vdc such as MSE173 when up to 7 drives can be incorporated in a single rack together with the power supply. For high speed operation the Power supplies type MSE562 & MSE875 are recommended for single and multi axis applications depending on motor current settings. Choice of full or half step drive The MSE570 may be set to operate in full step or half step drive. Half step drive is recommended since it provides increased resolution ( 400 steps/rev. using conventional hy brid stepper motors ) together with improved smoothness and damping of motor resonance. Thermal Protection A thermal sensor is fitted to prevent overheating of the output stages. The drive may be automatically disabled on over-temperature by setting switch SW1-1 on. Status LED’s for condition monitoring The MSE570 drive board has five status LEDs. The status LEDs provide a visual indication of drive condition. The function of each indicator is shown in the table. Surface-mount types are fitted as standard, with provision for the user to fit through- board types. These may be soldered into locations at the front edge of the board. Customising the MSE570 to meet individual application requirements Choice of external or internal step control In most applications MSE570 will be operated in conjunction wi th an external control source consisting of a clock pulse train to determine rate and distance together with a direction signal. Where operation off line from a control processor is required a print on the circuit board is provided for the user to add a simple voltage controlled oscillator to facilitate manual control of the motor drive system.
