A Bipolar Chopper Drive (not included) is a power-efficient method of 545 550 555 560 565 570 575 580 585 590 595
using current to drive a stepping motor to obtain high stepping rates. The hertz
chopper gets its name from the technique of rapidly turning the output Potential Applications
voltage on and off (chopping) to control motor current.
