MSE570 EVO 2

The MSE570 EVO 2 is a Bi-polar Stepper Motor Drive with pre-set drive currents. It features a chopped constant current output stage with on-board current settings from 0.5 to 3.5A per phase to meet the requirements of virtually any 2 or 4 phase hybrid stepper motor in the NEMA 17, 23 and 34 frame sizes. The use of chopped constant current drive techniques 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 drive and the motor. The drive is designed for use with rail voltages from 15 to 48VDC such as MSE173 when up to 7 drives can be incorporated in a single rack together with the power supply. The MSE570 drive board has five status LEDs. The status LEDs provide a visual indication of drive condition.
