Having issues with Aries drive not enabling. Cables appear ok. I can talk with drive, see status of drive, but I get a Hardware Drive Enable Error: Aries drive is not enabled via enable input? This was working last week, had to swap out drives to another machine while we had these drives sent out for repair. Re-installed repaired drives, but not enabling. Working with AR-04AE and AR-08AE drives.
The Hardware Drive Enable error means that you need 24Vdc across Pin 1 and Pin 21 (Enable+ and Enable -). What controller are you using? A common problem is that the active levels may be wrong on the controller side for the between the interaction of the Aries' Drive Enable Input and the Aries' Drive Fault Output. Meaning that the if the active level on the Controller side for the Enable and Fault are out of sync, the system will not enable. The controller will apply 24V to the Enable and the Aries will then turn off the Fault Output but if the controller misinterprets the Fault signal, it will disable the axis and remove the 24V from the Enable Input on the Aries.

thank you William!
These are (4)AR-04-AE Aries drives and AR-08AE drives.
I have green led on right side blank on left side... but when I tried to enable through PLC to home the the motors they immediately fault out in software but on the physical drive it still shows green led like as if they are enable and no fault. On the software it states the drive has a physical fault but nothing has moved.
What Error number is being shown when you use Aries Support Tool?
The Green LED does mean that the Drive is Enabled, so there is something else that is causing the drive to not move. Did you go through the configuration wizard to configure the motor with the Aries?
yes did configuration wizard. I know my parameters are correct because I loaded same parameters in a different AR-04AE and it operates normally. We had these drives sent out for repair as there was a direct short in a motor connection, unfortunately diagnosed incorrectly and a bit too late and took out several drives.
OK. That is strange. Ensure there is 24V across Pin 1 and Pin 21, then in the Terminal of Aries Support Tool, type DRIVE1 and check E39 and the LED. Then type DRIVE0 and do the same check. The DRIVE command should enable and disable the drive.
Let me know what the results are.
And I do not think the enable input circuit is damaged mainly because the LEDs and software status are saying different things. If it was the enable circuit was damaged, I would imagine that LEDs and the Software status would report the same thing and you would not be able to change it.
William,
I also have another Aries drive, labeled: CP*AR-08AE-14293. We purchased this drive used, but it acts differently that what I expect from using what we have at our facility here in Ithaca, NY. Would you know how to configure this drive to control in similar fashion to the AR-08AE drive?
Thank you.
I am about to go onto production floor to figure out pin voltages and follow thru your ideas. Thank you again.

Checked this morning and confirmed with 24v across pin 1 and pin21. Went into terminal: typed Drive1 - enabled no faults on status panel
it took a minute to go but then typed drive0: E39 not ready, S44.0 not ready and S44.1 not ready.
Just to see I typed drive1 again, everything in ready state. I went over to HMI where we enable the motion so to home out motor and when I try to enable it immediately shows axis fault 1, but the physical drive has green LED still and status panel is all in ready state?
I have another question about these Aries drives please. Why would the drive be able to lose its parameters while in operation? I have had to reload configurations a few times in random times while machine is powered and operational. Is that indicating a capacitor is failing or is the parameters are loaded on EEPROM and there is a potential board issue I should be needing to address.
Thank you for your thoughts
That part number is a custom product. I will have to do a little digging around to figure out what is custom about it
when i tried it in our setup of an X,Y,Z,R axis motion assembly and installed it for the Y axis, once it enabled it immediately drove to hit a physical limit? So it seemed very odd?
When your HMI reported the fault, did Aries Support Tool also report a fault or error? If it did, what was the error?
If it did not, there seems to mean that the Aries seems to be fine and there is something in how the HMI is interpreting the Aries drive. You may need to dig into the HMI to see how it thinks there is a fault.
Another thing to check is that the Fault Output on the Aries is working properly. Toggle DRIVE1 and DRIVE0 and check pin 9 and 16(the Fault Output). This should toggle between being Open and Closed. This is just an opto output see page 68 of the Aries User Guide Aries User Guide (parker.com)
One more thing. It sounds like these are all used Aries drives. You should use the RFS command and then download your configuration. The RFS command will return the Aries drive to Factory Settings.
we had one additional drive returned from repair and they replaced the circuit board, which basically means a new drive...correct?
that drive took parameters, enabled and homed out just like expected.
the other drives that were repaired all stated they had the capacitors and Opti coupler replaced.
But these drives are the ones that won't enable within software?
it did not report an error, everything remained in a ready state
it did not report an error, everything remained in a ready state
Is the Aries configured to be in torque, velocity or step and direction mode?
In both torque and velocity mode, the Aries just responds to the Analog input signal and servo control is handled by the motion controller so if there is any voltage on that analog input, it will just go until that signal is 0V.
right, I would think that too about the HMI and PLC...but if I take another drive and put it in place of this repaired drive I can enable the drive and it homes out in the HMI...so I feel there may be something else in the drive that needs repair?

As far as losing it's parameters check out this post (+) Why are Aries motor parameters missing? - Electromechanical Industrial Knowledge Base - Electromechanical - Industrial - Parker Community
type in the terminal RFS? then go back and run configuration wizard?
Yes RFS in the terminal... wait a couple minutes... then cycle power and then download the configuration
I tried the RFS command and reloaded configuration. Unfortunately, still same issue. I went to another machine with exact same drive\axis motor setup, tried this scenario to make sure parameters are good. Typed in RFS and then re-loaded configuration and that drive worked fine with my parameters.
OK... Is that while the PLC is connected to it? Those voltages are what I would expect if the PLC is not connected... If the PLC is connected then there is something wrong.
OK. If you take a look at the user guide and the diagram for the fault output, it needs to be pulled up externally and typically it would be pulled up internally in the PLC or motion controller. So basically it looks like the Aries drive is trying to remove the fault signal but since it is not pulled up properly the PLC still thinks it is faulted.
Do you see either 5V or 24V on the plc side if you remove it from the Aries pin 9?
so I believe the opto ILD223 has failed on the drive? I can't get voltage to change more than 0v to 0.395v. Would there be anything else that wouldn't let me conduct through the fault circuit? Should I be seeing 5v when conducting on 9 and 16?
i didn't see your last part of 24 or 5 vdc...i will look
This is my pin out voltages on one of our working drives:
24v across pin 1 and pin21
24v across pin9 and pin16
This is my pin out voltages for repaired drives:
24v across pin1 and pin21
0.3v across pin 9 and pin16
I verified on AB 2 servo card nothing shorted, and on Parker 71-025065-01 nothing shorted and all pins ring out.
This leads me to believe that the circuit board's fault circuit got shorted as well in the beginning with the motor being shorted and cross wiring occurred.
Does your team have replacement boards?
We do not sell replacements boards. The Aries line is obsolete.
But if you just got the Aries drive repaired, there is a warranty on the repairs. Contact the distributor that you set up the repair with us and let them know that the Fault Output seems to be blown on this repaired unit.
Thanks again, I did send those drives back to be repaired again.
Any info on that CP*AR-08AE-14293 would be greatly appreciated, maybe send a file of configuration to my email if you find anything?
Thank you for your assistance.
