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?    

Thanks guys for your help!

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?

ok, thanks.

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.

Thanks Scott, i'll give it try.

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.

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?

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?

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.

i am using Lobo machine corporation software on the PC to download user data to the PLC .

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.

set it to 0 using M8000 DMOV K0 D8120

set to 0 and still no communication.
