Designed for use with two-phase uni- and bi-polar stepper motors, the PCD-4541 four-axis control chip features built-in sequence logic for full- and half-step modes. This allows the device to output CW/CCW pulses or excitation signals directly to drive chips. Standard features include four independent-axes control, simultaneous start and stop of all axes, linear or S-curve acceleration and deceleration, speed change on the fly, idling pulse output for start, and a variety of limit signals. Price is $18 each/500. NIPPON PULSE MOTOR CO. LTD., Radford, VA. (540) 633-1677.
