Stepper Motor Drive Module

Haydon Kerk introduced its IDEA stepper motor drive platform, which now has the capability of communicating using an RS-485 data protocol. The main advantage of using the RS-485 protocol, the company says, is the ability for long data transmissions while exhibiting immunity to electrical noise. The RS-485 protocol utilizes “differential” signal lines for limiting common mode noise coupling and twisted pair cabling for cancelling out induced noise current. This allows IDEA devices to communicate over a network of 1000ft without the need for termination resistors. The system architecture also allows up to 256 addressable device nodes.

Hardware features of the IDEA Drive platform include programmable current control, a single supply voltage of 12 to 48 VDC, 2.6Arms (3.68Apeak) max rated current per phase, and 8 opto-isolated general purpose I/O. The inputs are rated for 5 to 24 VDC, 4mA max per input. The outputs are open collector, 5 to 24 VDC, 200mA maximum per output.
