Communication in 3G3MX no stable

[nguyenthanhcanh 3]

Hello, Before I have worked with 3G3JX, Modbus is good even many mistakes in the manual. Now I work with 3G3MX but this inverter not work stable in communication. I have set all parameters C70s, A001, A002 (the same with 3G3JX) I test with Multiway (read 1W, register 0001h), comm with 3G3JX is good but not stable with 3G3MX. Pls see the attached image (comm with 3G3MX) and give me an advice. Thanks Edited 27 Mar 2009 by nguyenthanhcanh
