How is the tolerance set for the movement? I assume there is a setting in the Ultra Master software for the servo drive to adjust it? ------------------------------ Patrick Dixon[Designation] PE, PMP www.DPAS-INC.com ------------------------------

My customer has a Ultra 200 series digital servo drive DDM 075 connected to 1746-HSTP1 module in a SLC 500. Every scan we send the same command distance through the HSTP1 as the target position, and we get back the actual and encoder feedback. We assume the drive uses the encoder feedback to control ...

I have a customer with an Allen Bradley DDM-075 servo drive. We want to look at the configuration/diagnostics in the drive, and we think we need Ultra Master software and Windows XP. How do we get the software? Is there any documentation on how to connect to the drive and use the software? ...

RE: Minor fault on LDLG when Lag<1

Thank for you the responses. I am glad to hear that the minor faults do not impact CPU performance. I generally don't like any faults to persist, so I am inclined to set Lag = 1 when it is less than 1 and use a SEL block to use the raw signal instead of the LDLG signal in that case, which adds some additional ...

Minor fault on LDLG when Lag<1

Found In Egroup: Automation Control \ view thread
I made an interesting discovery. I was getting minor faults with "(Code 04) Arithmetic overflow. Result of an arithmetic instruction out of range". I traced it to a LDLG block where the Lag value was 0.0. Documentation says 0 disabled the Lag, but internally it actually requires the value to be >= 1. ...

sqlservr.exe using 18% of CPU when FTVIew SE open?

I have a stand alone Win10 machine running Emulate v33, Logix 5000 v32, and FTVIew SE local. When I open my FT View SE application, I notice "SQLServer Windows NT - 64 bit" (which is sqlservr.exe) using 18% of the CPU. That seems high. My understanding is this is SQL Compact / embedded databases, no ...

I have Logix Emulate v33.00.00, Logix Designer v32.03.00 and I have some PlantPAX 4.0 objects in my code. I am running on Win10 Pro 64 bit. It is on my laptop, so there are no other users and it is impossible for any other user to be accessing anything on my machine. However, every time I try to download/upload/go ...

MAC address for downloading new config file to SLC 505

Found In Egroup: Automation Control \ view thread
My customer has a SLC 505, but does not have a commented config file for the current code. They have the original config file with comments and address descriptors. The code was never downloaded, so the MAC address is default. The uploaded code obviously has no comments or descriptors. They want to edit ...

I uploaded a PanelView Plus 600 and saved the MER file, but when I try to add it to the FactoryTalk ME Application Manager it says it is protected. I assume it is password protected? Is there any way to get around this, since nobody at the customer facility knows this password and the prior integrator ...

The facility has 2 identical machines. Machine 2 works perfectly, Machine 3 does not. The customer suspects there is something different in the PLC.
