  1. PLC(FX3U)-inverter(D700) Modbus too slow connection

    Andrius replied to Andrius's topic in Mitsubishi

    50Hz, stop command from Communication, Iverter after stop signal use DC brake, and stop time 0.0s(pr08) . Today test run signal from PLC output, better, but in test, same times it stops not in same place(I have same correction, too stop drive I have tested it's 33.0mm stop distance of line), like for example normal stops at 317.86 ir 316.98 but several times it stops 310.23 it's too much.. Why this happens?
  2. Helllo, I have same problem, PLC FX3U and inverter D700 (5 inverters connected by modbus(using Function block Fr700fx)). For me need to stop motor at same place, by encoder, start using Function block ModbusFr700FXControl, and stop inverters time 0.0s (pr08 in inverter) but some time it stops at time (example if by encoder have 317 position it stops 325, but in second time it must stop at 317 it stops in 365). Maybe communication too slow stop in time (parameters in inverter for communication : Pr332-192; Pr334-2; Pr340-2; Pr539-5...) Anyone have any thoughts or experience to do that at the very least stopping distance would be equal? please help!!
  3. Thank you for help, it works without problems.
  4. Only one inverter, and for me need write max Fregency, acceleration and deacialiaracion, then motor go foward and beck. Thank's
  5. I have software GX Developer Ver.7.04, and use hardware FX3G-14MT/DSS with FX3G-485-BD, Serial Communication with Inverter D-700, then I start writing few parameters to inverter, I have problem, then, write first its work's without problem, but after second parameter writ, first parameter I can't write, and I can't find any solution, or example how write and read same parameters from inverter. I am using FB for GX IEC Developer 7.04. tested in: March November 2010, I attaching to this message. Maybe some body have example, how read and write parameters from inverter? MbInvFx.zip
  6. Hello, I have problems then sending data, with my block(FB are attached). Firs time in first parameter then write it ok, then write in second or other, I can't write in ferst, I can't find problem, in simuliator work's without problems, bet in PLC it have this problem. Thanks
