Powerflex 525 Output Frequency Drops Out
VFD Guy replied to TAS's topic in Allen Bradley / Rockwell Automation
As stated, the rpm in wrong. Also, the flux current appears very high. I would correct nameplate info and retune. Sounds like your drive is hitting a limit and folding back -

Can I use CIP motion over network with third party servo drive
VFD Guy replied to Aniket_B's topic in Allen Bradley / Rockwell Automation
Does the 3rd party servo support CIP sync and CIP motion protocols? -

VFD Guy replied to Spromundo's topic in Allen Bradley / Rockwell Automation
This is correct. If no 22 comm module installed then you need a 1203-usb -

PowerFlex 400 - Output frequency issue
VFD Guy replied to PaulKim1003's topic in Allen Bradley / Rockwell Automation
The basics of VFD troubleshooting is to identify if the VFD is doing what it’s told. Compare commanded speed with output. Based on what you’ve stated it sounds like it’s not. This tells me the drive is hitting a limit and folding back. There should be alarms and limit statuses you can monitor. Another quick trick if you are in an open loop mode is to run without motor connected. If the it still cycles, you know to focus on the drive. If not, it’s a load or failure of the drive. At that point, I’d be looking at the logged alarms to understand more. There are regulators in the drive to overwrite the command to protect itself -

1203-USB is what you need for using the DSI port. The old model was the 1203-SSS. If the drive is on a CIP network that RSLinx supports then just use CCW to connect via the network -

I think you can do this with source protection which is outside of factorytalk. Not a password but still lock it down -

Kinetix 5500 Control Sync Fault
VFD Guy replied to Twigums's topic in Allen Bradley / Rockwell Automation
There are many on the knowledge base site. Some are tech connect so I don’t think I can post those here. Just search the fault name or number. My experience is that synch issues are caused by devices between the controller and plc. Check switches are set up with PTP, enable time synch with any enet modules. Things like that -

Apologies. I understood the opposite in the initial post that said stand alone worked -
Jogging powerflex 525 in hand mode
VFD Guy replied to Ezraseth's topic in Allen Bradley / Rockwell Automation
Seems like some good convo here. If I summarize it right. Your system works stand alone but not on enet. So I go to the basics of divide and conquer. If on the problematic drive, you disconnect enet and set the settings to keypad and pot and it works then adc is not the issue. Adc only triggers on comm establishments. If you still have the issue, I would look for not fault config params on comm loss. With enet unplugged and you power cycle, set up for him and pot and it works. It has to be some setting. Can you attach .iuux CCW file so I can take a look? -

Kinetix 5500 Control Sync Fault
VFD Guy replied to Twigums's topic in Allen Bradley / Rockwell Automation
K5500 don't need to be on DLR. Interesting that upgrading RSLinx fixed the issue. Nice find. I would look at the motion timing statistics in Studio to see collect data with this issue. Too much jitter will cause a synch fault. I use FactoryTalk Updater software (Free) to notify me when Rockwell's PCDC site has newer versions of software so you might be interested in that. -

Kinetix 5500S2 Fault FLT S54 POSN Error
VFD Guy replied to zarunas's topic in Allen Bradley / Rockwell Automation
This is caused be the planner not seeing enough counts of position and the motor is not where it’s supposed to be like stated above. Could be many things. I would start with motion direct commands to verify motor and encoder are working. Obviously open the brake if one is equipped -

CCW - failed to write a new value message
VFD Guy replied to PaulKim1003's topic in Allen Bradley / Rockwell Automation
The identity page has nothing to do with tuning. I would ensure the CCW profile is up to date. If a plc was connected, a tune wouldn’t be possible from CCW. Plc owns the Io connection as a class 1. In order to tune ie control bar to start it, a class 3 connection needs to be opened which can’t if it’s owned. This is why there is no control bar function in the AOP of logix
