Drive upgraded for motion control
Parker Hannifin has increased the flexibility and capability of its AC890 Modular Systems and AC890PX High Power Systems AC drives with the launch of high resolution analogue input and encoder option boards.
These option boards provide the extra inputs and outputs required in the likes of electronic line shaft applications, machine tools, and other demanding motion control tasks.
The 8903-EP encoder option board features an incremental encoder input for a reference encoder, and a synthetic encoder output. The encoder input provides optically isolated differential inputs on 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 synthesising an encoder output.
