A1SH communication to FR-E520 drive over CC-Link

[Guest Bloomers]

Does anybody no how to communicate to an FR-E520 drive over CC-Link from a A1SH CPU. I know it is done using TO and FROM operands but is there anything I need to do in the drive/comms board.

The only thing you should have to do in the drive it set the rotary switches for network speed and node address. In the PLC you use TO/FROM statements to get the data from the buffer memory in the CC-Link module to the PLC's memory.

Parameter 340 should be set to 1 and Parameter 79 set to 7 (cc-link mode) One thing that caught me out was that every time that the frequency command setting is changed (RWw1) you must set RY D (frequency setting command (RAM) and then reset it when RX D is 1

navillusi Do you have any example code for these drives and processor. I have writern a short program in GX ver 8 and am unable to test it until I get the equipment next week. It would be useful to compare against a working example. email: m.bloomfield@talk21.com
