Microstepping Truth Table

1 means jumper NOT installed

The XS-3535/8S-4 Stepper Driver is a 4 axis pulse-width-modulated (PWM) current controlled bipolar micro-stepping controller. Each axis drive has a +-2.5 Amp/phase @ 35 Volt maximum continuous Output Rating. The drive circuitry has thermal shutdown protection and crossover-current protection. Synchronous rectification circuitry eliminates the need for external clamp diodes in most applications. Each axis accepts Step & Direction signals, along with 2 jumper inputs to define microsteps per full step.

The board is of 4-Later construction with Isolated Power and Logic supply planes. The drive circuitry has a heat sink attached to allow cooler operation.
