Modular and Smart, Functional and Flexible

From simple step and direction input drive modules to smart programmable indexer/drives, PacSci has you covered with leading stepper drive technology. The 6400 Series is modular to support a broad range of application requirements. The modular design assures that you maximize your value - with only the features you need. Choose the method of control from simple step and direction inputs to full programmability. The reliable performance of the 6400 series has been applied over a wide industry base.

The heart of the 6400 Series is the step driver ASIC (Application Specific Integrated Circuit) developed by Pacific Scientific. The exceptional features of the series originate with this integrated circuit. A 22-pin header interface allows the ASIC to communicate with our option cards. Our engineers can also use this interface to provide OEMs with custom solutions.

Key performance features of the series include:

• Patented four phase bipolar chopper circuit electronically controls the motor winding currents at 20 kHz, reducing heat, audible and electrical noise
• Microstepping assures smooth low speed operation and optimum system resolution
• Digital Electronic Damping(TM) circuit eliminates the problem of mid-range instability and delivers full torque across the entire speed range
• Idle Current Reduction reduces motor current during inactive periods so stepper system runs cooler, extending motor and drive life
• Output current is DIP switch selectable in .625A increments from .625 to 5A rms continuous (7.1A peak)
