105-642001-01 Pacific Scientific Communications Card

The Danaher Motion / Pacific Scientific 6440 Series Indexers/Microstepping Drives communicate with RS-232, RS-422 or RS-485 serial protocols at 9600 baud. A simple single letter mneumonic code is used. Discrete I/O lines provide external start/stop, motor enable, ± limit ± jog and home inputs, and motor moving, step and direction outputs. The eight bi-directional discrete I/O lines are individually jumper configurable for input or output. Inputs one through four can be used as a parallel interface to select up to 16 different move profiles. This is ideal for thumb wheel and PLC interfaces. The 6440 operates in one of two modes; either Fixed Resolution or Variable Resolution. In Fixed Resolution Mode with binary steps, the step resolution can be set from 200 steps/rev to 51,200 steps/rev and with decimal resolution 200 steps/rev to 50,000 steps/rev. The step pulse rate varies from 0.08 to 19,000 pulses/sec therefore, higher step resolution limits shaft speed. In Variable Resolution Mode the step re solution is fixed to 20,000 steps/rev, and the speed ranges from 0.02 to 6000 RPM. The 6440 changes step size "on the fly" to provide both high speed and resolution. This package can be set up for two axis master, slave control. The indexer can provide synchronous or alternating motion for two axes through its step and direction outputs. The motion profile is trapezoidal with independent programmable accel and decel rates.
