  1. I am reassembling a machine from storage. I have connected the Allen Bradley variable speed drive to 3ph power and plugged in the keypad. I have set the P46 – [Input Mode]  set to 2 and connected a 3phase motor to T1 T2 T3. The 3 phase motor I am driving is not turning and there is no voltage from T1 T2 T3 when i press start on the keypad. This system worked prior to this. Its been a few years since I had this running. Am i missing something?    
  2. Question about chip PLC

    Hey, I would like to build a plc system for a residential elevator. I wanted to secure the code and was thinking of a chip based plc on a board with inputs outputs and input for encoder. Anyone here know where I can get a less expensive system like this around $200?  Maybe sourced from China?

    Thanks guys for your help!
  4. Hello, How do i measure pulses per second using the data from a High Speed Counter linked to an encoder? I have a DL405 and D4-HSC linked to an encoder on a conveyor drive shaft and am using Directsoft5. Thanks for your help.
  5. i am new to Rockwell automation and want to learn RSViw32. is there a demo version of this software available? Thanks in advance for your help.
  6. question about learning RSView

    Thanks Scott, i'll give it try.
  7. Lost communication PC to PLC. Need help

    I have a FX2N 16MR PLC with a FX2N-232-BD adapter board. the setup has worked fine for many years. Yesterday, the PC has not been able to upload values. Is it possible that the FX2N-232-BD adapter board parameters have been wiped out? How do i re-establish the parameters. I am able to connect with my laptop to the PLC using Gx developer and an 09 cable. The PC serial cable did come part way unplugged and 2 conductors were not working but i have since plugged it back in and still no communication. Thanks in advance for your help.
  8. Lost communication PC to PLC. Need help

    in my ladder program when M27 is on, it activates this [FROM K0 K29 D206 K1] and D206 shows the number 293. How do i find out which error this is? i have the PLC on my desk connected to GX developer and when i go into PLC Diagnostics it displays PLC/PP comm err and also Link error. there are no other numbers or descriptions. i see that link error is a serial communications error but is there a way to get the cause of the communication error?
  9. Lost communication PC to PLC. Need help

    I see the last tab cointaining the parameters. This FX2N PLC uses a EEPROM. should i be removing it to write the parameters to the PLC? or is it ok to store the parameters on the EEPROM. The PLC is asking for a keyword when i try to write the parameters to the PLC with EEPROM removed. i was going to disconnect the battery to wipe out the password. just wondering if there are other hidden parameters that i may lose. i have the ladder program and the Comm parameters backed up and the user data.

    I don't see the D8120 location in the ladder program, accept for where i moved 0 to it. Is that what i should be looking for? something being moved to the D8120?
  11. Lost communication PC to PLC. Need help

    i have attached a screen shotMy link of the parameters that came with the original PLC program. i'll test the software using my laptop if i can through the programming port.
  12. Lost communication PC to PLC. Need help

    i am using Lobo machine corporation software on the PC to download user data to the PLC .
  13. Lost communication PC to PLC. Need help

    D8120 came up as 0 when i rebooted the PLC. I then wrote the plc software to the plc including the parameters and then restarted the PLC and still no communication. it shows comm error in PLC diagnostics.
  14. Lost communication PC to PLC. Need help

    set it to 0 using M8000 DMOV K0 D8120
  15. Lost communication PC to PLC. Need help

    set to 0 and still no communication.
  16. FX2N-1PG ERR after changing PLC need help

    Solved. there were some negative numbers in the position and speed areas. Thanks for your help.
  17. FX2N-1PG ERR after changing PLC need help

    Hello, I have an error 173 on the FX2N-1PG. the light flashes when i send a signal to move the servo. This error showed up after swapping the PLC to trouble shoot another problem. the original PLC is back in place.
  18. FX2N-1PG ERR after changing PLC need help

    I don't see error 173 in the manual 067924.pdf. i am going to download the program again to the plc to eliminate this possibility.
  19. Hello, I am using GX Developer version 8 with Mitsubishi FX2n PLC. Can anyone tell me how to write a value to D700? the value will be 20000. thanks in advance for your help.
  20. How do I write value to D700 using GXdeveloper

    Thanks Gambit, I'm not connected to the PLC until tomorrow to try this out. After i go into device test, do i just type in MOV K2000 D0?
  21. comm error when editing, please help.

    using Melsoft GX developer 8.107M and FX2n PLC i have not used this software for a while and am trying to edit some of the code. Please help. I am not connected to the PLC at this time. In write mode i double click T3 and change to T4 and click ok. after this i right click screen and select convert. the software waits for a second and then gives me this communication error. "The data which was downloaded from th elc is incorrect. The likely causes areas follows. the mistake is found in the transfer setup. the comunications between the PLC and the peripheral is unstable because of the abnormal cable or abnormal H/W or the noise etc. the data in the PLC is broken. <ES:01802007>" how do i edit the ladder without the error message?
  22. comm error when editing, please help.

    Thanks Gambit
  23. H4-CTRIO EDGE RESET question

    My application requires me to place 2 grooves in the edge of a board as it goes past a stationary router. the board is is moved past the router sandwiched between upper rollers and a lower conveyor. The board position is recorded by an incremental encoder. My plan is to use a mechanical limit switch connected to the edge reset function to detect the beginning edge of the board and then use the preset table to operate the router in and out with a discrete output to make the 2 slots. My question is, will the counter start counting again right after the reset while the limit switch stays closed (using the edge reset function) while the full length of the board continues past it? the instructions seem to indicate it will but they are not 100% clear. Thanks in advance.
