Good Day! Is there any one who can share me an old software for A171SHCPU motion controller. SW3RNC-GSV? I am converting it to Q173HCPU together with all servo systems. I tried asking local distributor but they have the new on MT Developer only. Thanks!

I would like to get the process value PV of the yokogawa controller by using RS485 communication? Maybe you have tried it before?please help.

Hi! I am new here. I would like to ask help from you guys regarding synchronization of two different VFD's using Mitsubsihi PLC. The master VFD is Mitsubishi while the slave VFD is UNICO both with the same line encoders. I got analog reference signal from the master VFD and then sent to the slave VFD to synchronize but I noticed that the slave VFD has different response, causing the slave machine to lag. Maybe you can give me advice on how to correct this problem. Note: Each VFD drives paper printing machine, so every time they do not synchronize the paper loop is cut.

Inntele, I find this solution interesting. Please check it out. Thanks! A700-Electronic-Gearbox-Control.pdf

Hi! Maybe you can help me on this. Do you know some tutorials for VB linking to Mitsubishi Q series PLC. Example: 1. Monitoring 16 bit and 32 bit data. 2. Monitoring bits devices like ( M,B,L) Project is all about monitoring only with provision for control in the future. Thanks!

It is from Mitsubishi Electric System Service in Nagoya, Japan. It is one of their SCADA software but some agents refer to it as a very complicated soft. I have attended the training for this, the thing is about the graphics which is made in VB platform and I'm not so familiar with that and is my problem right now.

I am attaching a printscreen copy of the software. SA.xls

I am setting up MR- J2S amplifier,. I have setup161e.

Is it possible to copy and setup an OEM Servo Amplifier parameters?

Oh I see,. Thanks!

The SA1-III has window for VB exe files. It's setup is not that complicated but the only problem is you have to build graphics in VB platform. Any VB program made can run in this software but in this case I need to run it with OLE also. Anyway, you might be able to help me create VB projects linking to Q series PLC.

I'm sorry for that. Anyway, my project is to monitor 4 remote areas using Mitsubishi SA1-III software and I want to build the graphics in VB application. The project is for monitoring only and provision for control. I need to monitoring flow rates, liquid levels, pump status,ph level. Customer wanted a very good graphics. Maybe you have suggestions to facilitate their requirement. Thanks

I suppose plcfreak is referring to Positioning mode of FR-A series and I think I'm going into that direction. You are right it is really impossible to synchronize 2 VFD's different brands with speed and phase. I tried before synchronizing 2 MR- J2S and 1 FR-A700 in positioning control mode and it worked. Right now I want to propose them changing UNICO drive to Mitsubishi since I'm not so familiar with their drives. The question right now, what is the best setup? The machine which runs FR-A500 is in CC link network while the other machine which runs UNICO uses only analog signal. I hope you can give me a better idea. Thanks!

Does each PC for monitoring need these libraries?

The master right now is using FR A500. Is it possible to synchronize it with FR a700 using those cards? By the way, is the master VFD necessarily in position control mode just to get the feedback pulse(pulse division output)?

Using FX3U plc can I use its built in PID function to control the UNICO vfd to make this system work?

By the way, I would like also to ask if PID function is applicable into this kind of system?

I already tried recommending to change the other drive into Mitsubishi, but they are still working out on the budget. Anyway, I appreciate your kindness to share your ideas to me. Thank you so much.

Yes, there is a difference in response between the two drives. I already recommended before changing the other drive into Mitsubishi but I think they are still working out on the budget. Anyway, thank you so much for your time in sharing your ideas.

I need to synchronize speed together with phase, it is critical for the output of the machine. Maybe you have more ideas, please kindly share it.

The speed matching is a bit critical because aside from the paper loop to be cut, the cutoff point is also affected. It is a newspaper printer machine, whenever there is a mismatch there is shift in printing also. We already tried to recommend to change the UNICO VFD into Mitsubishi since the Mitsubishi VFD has Positioning function so it's better to synchronize with the master, but the client insist to use the old VFD. Maybe you have other suggestions to make this work.

Analog signal from Mitsubishi VFD is the master reference signal which is inputted to FX3U-4AD then I output analog signal to the UNICO VFD through FX3U-4DA. I used the two encoders for angle comparison if the other is leading or lagging by certain angle then I compensate the speed of slave VFD(UNICO).

I am using FX3U together with FX3U-4AD and FX3U-4DA.
