Aug. 19, 2010 - PRLog -- SSD Drives Division of Parker Hannifin Corporation, the world’s leading manufacturer of motion and control technologies, has announced the launch of two new option boards for electronic line shaft applications, machine tools, and other demanding motion control tasks. The new option boards, offering high-resolution analog or encoder input, increase the flexibility and capability of the AC890 and AC890PX drive families.

The 8903-EP encoder option board features an incremental encoder input for a reference encoder and provides a synthesized encoder output. The encoder input features optically isolated differential inputs for channels A, B and Z. All inputs are compatible with RS422 and RS485 encoders, as well as encoders that provide output voltages as high as +/-30V. The board embeds all the decoding logic required to interface the encoder input to the drive's microprocessor, providing true plug-and-play connectivity. Three non-isolated differential digital outputs are used for synthesizing an encoder output. Installed on a drive along with an 8902-EQ incremental encoder option, the new board can be used to create an electronic line shaft between the reference and feedback encoders.

The 8903-AI card adds a high resolution analog input to the AC890 and AC890PX drives. It offers all the functionality of the 8903-EP encoder option board, as well as a 16-bit +/-10V analog input. This makes the drive suitable for machine tool applications, where the drive will typically follow a precision analog speed set point from a CNC and send back to the CNC the position of the controlled axis. It provides the fast response times required for accurate position control.

Complementing the existing line of option cards, these two new releases add even more flexibility and functionality to the AC890/AC890PX family. For more information, including technical manuals, please visit
