· Output pulse rate: 400 Kpps· Practical rate; theoretically max. 2.4 Mpps
· Linear and S-curve acceleration/deceleration· Two-phase stepper motor excitation sequence circuit built-in· Simultaneous start/stop
· Pulse output on multiple axes within one chip or on multiple chips can be started simultaneously by the command or external signal. Pulse output on all axes can be stopped by the command, external signal, or failure on any axis· Idling pulse output (1 to 7 pulses)· Overriding operating pulse rate during operation in progress· Four major operation modes

2. Excitation Sequence Signal Input Driver IC
Low-cost versions dedicated to stepper motors
The PCD4500 series chips are low-cost, programmable pulse generators equipped with an excitation sequence generator circuit to drive two-phase stepper motors. Placing a stepper motor drive IC between the PCD and each stepper motor enables the user to easily configure a multiaxial motion control system. Each model can output a pulse train.
