RE: Stuttering on cold startup with 6000T VFD

Hey GLaDOS, Thanks for your reply. The drive is rated for 2250HP, and the load is quite a bit less, so I don't think it's a sizing issue. I may try a custom start up ramp, but for now I was able to slightly decrease the accel time for a better result. With the new setting I was unable to see any wibble ...

GLaDOS, I have theorized that the 60 second accel time might be part of it. We had some weird behavior with a long decel time as well we had to work around. It's on my list to test during the next shutdown. As for the Acc Boost, I don't think it is available under the Induction SV MtrCtrl Mode ...

Stuttering on cold startup with 6000T VFD

I'm having an issue with a 6000T and I'm not sure what parameter might be best to address it. The drive was already tuned for both a no load and loaded run by an MV specialist. The conditions are below: Our DCS gives the VFD a speed reference of 1500 RPM on startup and the VFD handles the ramp up ...

RE: 6000T Drives and DLX

This turned out pretty well. I have an option card on each VFD feeding directly to an interposing contact in the paired cabinet. The DLX logic is such that if the drive status goes off, it immediately changes from High to Low on the Relay going into its' twin. We now have both primary protection by the ...

In this case the Drives are set to coast stop when ethernet comms are lost, but I never did find a way to directly communicate between the drives over Ethernet/IP. I've settled on adding an option card for each drive and running discrete interlock signal cables between the two for a mutual interlock. ...

6000T Drives and DLX

Greetings, I have an application to create a 'drive to drive' connection for trip. We have a pair of 6000T drives that normally receive start/stop commands from a central processor, but due to some expensive lessons, we are now determining how best to have the drives communicate their status directly ...

Ian, That was valuable feedback. I'm now reading a different register that is a single unint16. Which isn't the data I need, but it is confirmation that data is flowing from the device and is not shifted. 3000, 3001, and 3048 do not fail and correctly pull in the data when Transactions[0].Count ...

Hey Ian, I've tried both transaction codes 3 and 4. And all combinations of 3&4 with register 4000, 4001, 4002, 4003. For verification I've connected using PowerHud ModBus Tester, and the devices are all on the same SCADA bus (subnet and vlan). Thanks for your feedback. I'll have ...

Hey, I'm trying out the "Modbus TCP Client Add-On Instruction based code for ControlLogix® and CompactLogix® controllers" (Modbus TCP AOI ver 2.04) from Rockwell. Specifically, the Client rung to pull data from a Modbus TCP Gateway. The AOI block itself is showing Sts_En and Sts_Connected on with this ...

Philip, Thank you for the prompt response. I have been looking through the servers this morning and do not seem to have the FTSystem Status Portal. I am not certain if this is an additional install. We are running network distributed FT view SE version 14. I was able to find help files related ...

FactoryTalk View SE - Status of Primary/Secondary server for scheduled maintenance.

Found In Egroup: Advanced Software \ view thread
Greetings. We are set up with two versions of FT View SE. For the sake of planned server maintenance, we'd like to be able to read the Primary/Secondary server status and allow a windows server reboot based on both a time basis and the server status of the alternate server. I.E. If Primary is OK and ...
