Danaher Motion’s Pacific Scientific 6445 is an economical, high performance microstepping drive combined with a programmable indexer. The package uses an RS-232/485 port to allow single or multi-axis communication at 9600 baud. 16 programmable inputs and 12 programmable outputs are compatible with standard 5 to 30 VDC I/O. The 6445 features 12 k of battery-backed RAM for storage of parameters and move profiles. Motion control programming is simplified with Danaher Motion’s Stepper BASICTM, an easy to learn extension of the BASICTM protocol.
Resolution with 1.8º motors ranges from 200 to 51,200 steps-per-revolution. Step sizes are in decimal increments. Higher resolution (microstepping) provides smoother operation through low speed resonance regions. A patented Digital Electronic DampingTM circuit ensures the availability of full motor torque at all speed ranges by damping motor oscillations common with stepper systems. Full motor torque is achieved throughout the speed range whether in the full step or microstepping mode.
