RetiQlum Posted October 2, 2020 Report Posted October 2, 2020 I'm having trouble with some Powerflex 525 drives. Right now what I need to do is run them manually from the keypad to test conveyor belts. Is there a way to do this and if so how? Thanks in advance.
TimWilborne Posted October 2, 2020 Report Posted October 2, 2020 Are they brand new out of the box? If so turn the potentiometer to the right and hit the green button the the keypad.
RetiQlum Posted October 2, 2020 Author Report Posted October 2, 2020 No. They have been pre-programmed.
TimWilborne Posted October 2, 2020 Report Posted October 2, 2020 Study on parameter P046, that is your command source, and P047, that is your speed reference. 2
RetiQlum Posted October 2, 2020 Author Report Posted October 2, 2020 Thanks so much TimWilborne. It worked for some of them. Of course there was a bad drive in the bunch. And one I had to factory reset. I appreciate it.
RetiQlum Posted October 3, 2020 Author Report Posted October 3, 2020 One more question: If I have a 525 configured for 2 HP by factory defaults but the motor is 1 HP can I leave it like that? If not, how do I set the parameters to 1 HP without causing a Mismatch C-P error. I had a couple of drives set to 1 HP. Rockwell support told me to reset to factory settings. Now they pop up in RSLinx as 2 HP drives. Sorry for the weirdness here. I was dumped on site with no former knowledge of the company and how it sets things up.
RetiQlum Posted October 3, 2020 Author Report Posted October 3, 2020 You can disregard the former question. I was informed that it is OK (at least in this application.)
VFD Guy Posted February 3, 2021 Report Posted February 3, 2021 Mismatch cp just means the control pod was changed. Reset this. Set the motor data and your other parameters and you will be ok. Try not to go more than 2x drive size or the drive can’t protect the motor
Erdal Arslan Posted February 24, 2021 Report Posted February 24, 2021 (edited) It could be less important if the load is a pump or fan but for a better motor control and motor protection you should set to 1HP. Edited February 24, 2021 by Erdal Arslan
JustinSmith Posted March 22, 2021 Report Posted March 22, 2021 (edited) We like to add all of the specific parameters needed in the electrical drawings. I also like to keep a printout of all the parameters. https://rexel-cdn.com/Products/39E62596-1DCC-4029-9363-F11286CC741A/39E62596-1DCC-4029-9363-F11286CC741A.pdf Edited March 22, 2021 by JustinSmith
