The Critical Velocity AI-STEP XC is a powerful and versatile stepper motor position controller (indexer) capable of driving unipolar and bipolar stepper motors up to 3 amps per phase.

A full-featured menu-driven jog-dial interface allows stand-alone operation without a computer. In addition, a 100 position memory allows for quick recall of stored positions.

A serial interface allows computer or MCU control of the motor and AI-STEP configuration options.

The standard TTL STEP and DIRECTION interface allows for basic interaction while maintaining full control of maximum speed and acceleration of the motor.

Control Options:

• Stand-alone Manual Jog Dial Operation or
• Optoisolated RS-232 Serial, Inverted TTL Serial inputs for computer control or
• Optoisolated TTL STEP / DIRECTION inputs for logic circuit operation

Memory Features:

• 100 position memory accessible via jog dial or serial interface
