Motion Control Chip drives stepper motors.

Press Release Summary:



2-axis PCD-4521 controls two-phase unipolar or bipolar stepper motors. Sequence logic for both full and half-step modes is built-in. It can output CW/CCW pulses or excitation signals directly to drive chips, provides independent control of each axis, and controls simultaneous start and stop of all axes. Features include linear or S-curve acceleration and deceleration and idling pulse output for start and various limit signals.

PCD-4521 - New 2-Axis Control Chip from Nippon Pulse


Nippon Pulse Motor Co., Ltd., Radford, VA - (December 7, 2001) Nippon Pulse Motor Co., Ltd. (NPM) would like to introduce a new 2-axis control chip known as the PCD-4521.

The PCD-4521 is designed for 2-phase unipolar or bipolar stepper motors. The PCD-4521 can output CW/CCW pulses or excitation signals directly to drive chips since sequence logic for both full and half-step modes is built-in. The main features of the PCD-4521 (64-pin QFP package) are independent control of each axes, simultaneous start and stop of all axes, linear or S-curve acceleration and deceleration, idling pulse output for start and various limit signals.

The PCD-4521 makes multi-axis stepper motor systems easier and more cost effective to use. The price for one unit is $15.46. The manual for the PCD-4521 is available in electronic format. Major applications for this product are high-end office automation, semiconductor manufacturing and inspection equipment, robots, analyzers, medical examination equipment, and automatic handling equipment.
