Product Description:
Pacific Scientific is a manufacturer known for producing reliable and high-performance motion control products. Their product line includes servo motors, stepper motors, drives, and controls. One of their widely used products is the 5430 Stepper Motor Drive which provides precision and versatility in industrial automation applications.
The 5430 stepper motor drive operates with an input voltage of 120 VAC at 60 Hz and has an input current limit of 5 Amps RMS. It utilizes a two-phase bipolar chopper drive circuit that is current regulated with a nominal bus voltage of 65 Volts. For protection, it includes MDA 6 fuses on both 120 VAC input lines. The drive offers micro-stepping capabilities and current boost at step rates above 500 full steps per second that allows for enhanced control over the motor's operation. Its step size is selectable via DIP switches and ranges from full step to 1/125th of a step. In terms of current, the 5000 series drive supports a full step current of 5.0 Amps ~ 0.1 Amp and micro-stepping at 3.5 Amps ~ 0.1 Amp, with a boost function providing 5.0 Amps ~ 0.1 Amp under specific conditions. With an optoisolator power input range of 5 to 30 VDC and a maximum power dissipation of approximately 40 watts, the drive is designed for both efficiency and protection against overheating and short circuits.
The 5430 stepper motor drive is equipped with an Idle Current Reduction (ICR) feature which automatically cuts motor current by 50 % during idle periods that reduces heat and conserves energy. The ICR activates one second after the last pulse and restores the full current during the next step. The drive is also protected against short circuits and overheating, and it includes a translator circuit for handling step and direction inputs.
