Great video. Good explanation of where things get connected and parameter setup.
Thank you. Here is one I did on backing up the parameters using CCW.

Thank you very much for this video!!
You are welcome Ryan.
great vid. Great topic.
Thanks Dav Cot!
Great video i am running a harmony wireless controller and start / stop push buttons via two relays , stop NC and start NO and couldn't get the drive to keep running . thanks
for your help
You are welcome!
Hi wich type of motor you are connected in the inverter driver. I can see a cooler. Can you provide the specifications? Please
Hey, loving your videos, I have a treadmill that had a Hyundai N50 drive running it, now I have a powerflex 525 as the N50 popped, I am leaning towards running an external start/stop and Pot up to control board but was curious if the existing serial cable could run the 525 off the factory treadmill controls
Wow Kurt, I don't have a clue but would love to see your conversion. I would guess it is some type of serial protocol coming from the keypad. You might be able to use some packet sniffer to figure it out.
Great
Thanks from 🇵🇸 🇵🇸
You are welcome
I’ve been fighting a 523. Did plenty of reading, figured I was doing a simple 2 wire for start/stop. Set the parameters I needed including t062, but I’m confused by the use of t063 in your video. That parameter is used for terminal 3, is it not? To truly use the 523 as start/stop, will it not work unless it’s expecting a three wire?
yeah, it would help A LOT if you could also add the diagram on how you wired the pushbuttons to the 525.
Hey Tim. Is there away to use the I/O on the drive to turn a light on if it faults? The relay terminals could be used to tell you when it is running vs stopped. But I'm not sure about being faulted. Also along that line could you wire a reset button if faulted?
Relay 1 switches off when you have a fault. You would need to add an external relay to reverse the logic but it should do the trick. Also Relay 2 is Normally Closed so you could configure it for Ready/Fault and you could do it without the external relay.
Thanks.
You're welcome!
Question, Is it possible to use this drive and display freq. and current on remote HMI? would also like to be able to reset faults if that's possible.
Thnaks
Yes, those registers should be available over Modbus for direct communication between the HMI and the drive. It is on the list to make a video about.
Hi can anyone pls explain how to run in different speed from terminal block
Do you happen to have a video on installing a jog button function with the 525?
Yes you would use the 2 wire control for that. See link below.

Thanks, your the man 👍🏽
@@hoosierdealer6521 You are welcome, glad I could help!
Hi, I notice that your using a momentary PB for your start button. Is there a parameter that I need to configure to have the motor continue to run until the stop button is pressed?
Yep, check out around 3:15 of the video where we change P46 and T62.
Hi Tim, Here's a question for you. Using a Powerflex VFD configured as a 2 wire setup with both forward and reverse hooked up. Let's say you also assigned terminal position 6 to dc injection braking and have that on a switch. What would happen if you have the forward switch closed and the vfd is driving the motor and then you close the switch on pin 6 without turning off the forward switch. Will the vfd override the forward command if the switch is still closed and the signal is still being sent? Is the answer different if the switch for pin 6 is actuated momentarily or held? Will it resume forward as soon as the pin 6 signal goes away?
Putting a new vfd on a mill and considering tying the spindle brake switch into the vfd as a dc injection stop method whereas just turning turning off the forward/reverse switches will coast to a stop. I suppose worst case if the unit doesn't play nicely then I could have the spindle brake switch drive a contactor which breaks the forward/reverse switch signals AND triggers input 6 for dc braking.
I'm pretty sure the DC braking would only be active during deceleration even with pin 6 so the forward would override it but you better ask Rockwell Automation to be sure.
@@TimWilborne That makes sense. Guess I'll probably do a contactor to be safe. Reaching them as a diy guy is proving to be pretty difficult. You cannot even chat with them if you don't have a special account which is a little disappointing.

Are you using a single to 3 phase PF 525 , and just running 2 legs to the fan motor?
Want to know so I can build one like yours
No, drives that accept a single phase input create a three phase output. There are three wires going to the motor, just like any other 3 phase motor application.
@@TimWilborne where can i find a fan motor thats 3 phase like that? also i start hershey on the 7th. little nervous. been studying like 4 hours a day
@@TimWilborne yes Tim I too would like to know what fan that is so I can also replicate. Thank you!
I have 2 powerflex 400 in an air handling unit... If I just run one vfd, the other motor is freely rotating because of the air flow and when the second vfd from zero, it's getting trip... Is there any parameter to start the vfd from the frequency which it's freely rotating???
If I'm following you correctly, the bigger issue is the fan is rotating backwards when you go to start it. It requires much more load to reverse the motor than to simply start it. I think I would reach out to Rockwell Automation on this one but I suspect you need to increase the acceleration time.
@@TimWilborne thanks for the reply... The motor is actually rotating in the correct direction only...
@@premlal00007 What fault code are you getting?
How were you able to run the drive without jumping the safety S1 & S2 to S+ ?? I recently tried to re-commsion a used one, I had all of the parameters set correctly including T105 to 1 (disable) it would not move, an Allen Bradley tech said those jumpers were required and it worked.
Great question! From the factory there is a small red jumper between S1, S2, and S+. You can see me remove it in this video, chances are your drive already had it removed.

@@TimWilborne
You said you removed it......so did you edit out reinstalling it ? Or were you able to run without it somehow ?
@@JohnSmith-lv8xk The link in my previous reply was a different video. In this one it is as it comes from the factory with the jumper installed. Check out 1:39 of this video and you can see the jumper installed.
@@TimWilborne
Thank you ! That thing is really easy to miss !
You are welcome John.
We connect 1,2 and leave jumper wired to a relay as a safety. Every powerflex gets a relay.
Why t62 and t63? I’ve had to replace a few drives at work and did everything using the quick start guide but never would have figured out you had to change t62 and t63 without watching your video
Those configure the purpose of the particular input on the drive.
Can you wire an e-stop to the stop of that drive? Ive seen many drives fitted with contactors that cut power to the drive when an e-stop is pressed. Why do they do it like that?
Yes, the Powerflex 525 has a safe torque off feature which overall is much safer than fitting drives with contactors.
@@TimWilborne yes we have 2 drives that are wired that way at my plant, estop cuts 480V to drive through contactor, and both those drives are the only ones to have fried in the last couple years.
Going forward I've wired new drives with estop cutting the enable signal, is this the correct way?
No! The enable signal is not for use as a safe stop
Tim will you continue to sell these trainers with nothing but the PB's and wires. I don't see it on your website for purchase anymore
We thinned out our trainers and got rid of many of the slow sellers to make it easier for people to find the one they needed. There were almost no sales of it.
You dont mind selling me one of those if you have a spare@@TimWilborne
At 1:04 you mention terminal 11,2 and 4. Then at 1:32 you use 11,1 and 2 terminals. Does this have something to do with snk and src?
Misspoke Chuck. 11, 1, and 2 are correct
@@TimWilborne Thanks TIm! I replaced a Powerflex4 with a 525. I'm a MechEng that knows just enough about freq drives to be dangerous. Couldn't get the "new to me" 525 working until I did a FactoryReset and then she took right off! Thank you for the time you put into your videos. I really appreciate it! Question concerning the MOV: My incoming power is 240vac 3p. My drive is wired to a 4 pin plug. I have 240vac between any two phases and about 138vac between any phase and the 4th pin which I'll call neutral/ground. Do I remove the MOV or leave it in place?
Have you ever dealt with a fault code F-111?
Check your safety circuit.
@@TimWilborne will do thanks.
Thanks.
