Yes, I have experience with A800 and Modbus. Why don't you send me the response from Etherway, and we could see a lot from that.

I've sent you DM.

  It has Modbus, CC-Link (all versions, Serial&Ethernet, IE, TSN), Profinet, Ethernet/IP, Mitsubishi Inverter Protocol, Profibus, Devicenet, CANopen, Controlnet, FL-Net, Lonworks, BACnet, SSCNet, EtherCAT. Some of them are standard, and some of them are as option. So Modbus is far from only protocol. About Modbus implementation, I am not 100% sure if it has Modbus FC23 Read/Write, but other than that I don't see how it is lame. There is one thing with Mitsubishi VFDs and that is that Parameters Number are practically always the same in last cca 35  years, on every model Mitsubishi is adding parameters not changing them, so you don't need to learn it again,  but it tends to be confusing for new guys. As remedy there is FR Configurator Software that helps a lot.

I suggest that you to download Omron EtherWay app (it is free of charge) and test communication and post response. Also on myMitsubishi site, there is example for GOT HMI and E800, with Modbus TCP/IP and it is very similar VFD (in communication sense).  The example is called "FR_E800_EPA_ModbusTCP_from_GOT2000_and_NZ2FT_MT_Slice_IO".

It look like you have not used it. From my experience, if you want job done it is the best ever VFD I have used (and I have used many different VFDs from various producers). Just to mention that PLC function  inside it has, that is very powerful. I have used it for several application where servo was originally intended . Only drawback is the price. Maybe my language barrier is making problem to me, but I don't understand what are the problems you noted with frequency/speed reference. You can program it to have three control modes that are selectable either from VFD or through communication, and every mode can work in different way. I think that it is benefit not drawback.

I have made my own PID for Q series, and I have used it for more than 50 PIDs simultaneously. The processes were not to fast (mostly 100ms sampling). If you make your ow function, at the end it will all depend of CPU processing power. With L26 it should be easy to do it, with  L02 I don't believe it is possible, with L06 depending of memory capacity other already used for other function (very likely you can do it).

You should use h06 or h10 for writing holding registers.

If you look on the site https://us.mitsubishielectric.com/fa/en/support/parts/parts-catalog/HAR-07031/, you will see that it is also known as MMF-06F24ES-RP3. Reference number for MMF-06F24ES-RP3 is 230738. (https://mitsubishi-electric-eshop.mee.com/mee/FA_IA/en/EUR/Catalogue/Servo/Spare-Part/MR-J3-200A-350A-FAN-MMF-06F24E-RP3S/p/000000000000230738). Never tried it. It is fan for MR-J3. Hope this will help you.

If you remove fan from FR-CS, you should see part number. For Freqrol fans it usually starts with BKO, MMF or KO. 

If comms fail it means that there is nothing that can be sent to drive. However E800 has PLC function inside, so you can make comms "hearbeat" function, and do the reset from VFD if there is no communication after certain period.

If you buy GXWorks3 than you get GXWorks2 also.

It seems that you have bad program. Look at tags "Jogging" and "JogEND".

It is generally called AlwaysOn. Documentation for FX5 is excellent and quite big, I suggest you to read it.

You must use DHSC command.

FX3 is extremely reliable, so I doubt that it is hardware failure. You could post your program so we can analyzer situation. 

if USB-RS232 converter has original FTDI chip it will work, and it is not expensive.

This is original cable you need: https://www.radwell.co.uk/en-GB/Buy/BEIJER%20ELECTRONICS/BEIJER%20ELECTRONICS/SC-09?redirect=true

High Speed Counters are processed with special commands, because the speed of input signals is faster than PLC cycles. See commands DHCMOV, DHSCR, DHSCS, DHSCR and OUT_C. Basically, my suggestion would be to use the previous commands to set the counter, compare it and copy it. For example, set the counter preset value to 1,000,000,000. Copy the value of C251 into a 32-bit register (for example D500 and D501), using DHCMOV. Each time the set value of 1,000,000,000 is reached, increment the next register (eg D502) and reset C251 and start counting from the beginning. If you do not use dedicated commands, and maybe even interrupts, the counting will not be accurate.

We need more information in order to help you. My suggestion is to attach your code so we can analyze it.

With Beijer, often is problem with driver. If you have different driver installed on HMI than with E-Designer it often makes problem.

With ACPU you should use M9036. You need SC-09 cable for programming, and it has RS232-RS422 interface in it, as programming port on CPU is RS422.

What error E-Designer gives you?
