RE: Synchronous Capture Of Encoder Positions

Posted By Austin Adams Nov 09, 2025 05:30:59 PM
Found In Egroup: Automation Control \ view thread
Ah, I see, this would have to be in the 5069 series HSC? The 1734 series only have 1 channel. There is the trick of synchronizing Ch1 current count to match Ch0 current count since the Ch0 Z pulse will reset Ch0 only. If there was a time when they were idle and no latency I could preset Ch1 to match ...

Philip, Thank you for the suggestions. I have also done something similar before by landing the same encoder on channels 0 and 1 of a 5069 series HSC. Then I could configure them differently and get different data. However, in my current application your suggestion of using the Z pulse from the first ...

Hello, I am working on a system where we replaced Modicon PLC hardware with AB. There were 5 encoders that came into TSXCTY4A counter modules and during operation they rotate together with a phase advance and retard. The first encoder is the datum, and then the other 4 determine their registration ...

RE: Merging A MAG On A Jog

Thanks for the ideas. I ended up testing with the virtual master that always runs at a constant speed, then would MAG to that in place of jogging, and MAG to the primary when needing to speed match. It provided the desired result. The speed match happened immediately, so I could do a comparsion of the ...

Merging A MAG On A Jog

Hello, I have a question regarding merging a motion axis gear onto a currently jogging axis. The behavior is such that a roll is idling with a jog, then, when requested to gear it will clutch in, accelerate to match the master axis speed and hold. Since a MAG does not merge other motion instructions, ...

Michael, Another option is to look into Master Driven Axis Control. This lets you create a master / slave relation without the use of a cam profile. If this is initiated, then a MAM can be initiated on the master and even though the slave has a different distance to travel it will ensure they both ...

RE: 1734-485ASC Connection

Okay, thanks for clarifying. However I still don't know why it says 'data is received on S-'. Since the binary mark and space is generated by the differential voltage of the two wires. I'll connect it and test it. Thanks

I have installed several Red Lion displays before that have the RS-485 serial communication adapter, and connected them to the PointIO 1734-485ASC module and then written to them from a CompactLogix PLC. It worked great, but I don't think I properly documented the wiring connection, and now I need to ...

RE: Powerflex 755 Fast Acceleration

Rahul, The PowerFlex 755 has a feature called Torque Prove that works well for this application. Appendix C of the programming manual covers the setup of this. Basically you would want to set P1100 bit 0 to 1 to enable torque prove, then increase the brake release time in P1107 to a higher value ...

Michael, Batman has a good method described. I assume that you are using incremental MAMs throughout these 100 or so stops. Another method that I have used in similar situations is to arm the MAR prior to the last needed position. Then, executing an MRP of type relative. If the sensor position happens ...

There are a number of things it could be, but just a quick few notes would be to make sure your shortcut to the PLC is valid, then be sure to use the (::[shortcut_name]tag) syntax when addressing the PLC from your HMI.

RE: Combined MAPC with MAG

Thank you, I will make sure the MCSV value returns the needed value. I have looked at the offset MAM types but this does not feel like the correct application. If the primary motion were the cam, then the offset would be ideal. There will be dead dwell time in the cycle when the cam is waiting for ...

Ok that's great to hear. I'll continue putting this all together. Since I don't want the MAPC positioning to be a factor in my register value calculation, it's a perfect application of a MCSV. I will subtract out the cam position with the Motion Calculate Slave Value. Thanks!

Hello, I am working on adding a feature to an electronic gearing design that we currently use. The application has several Kinetix rotary axes that MAG to a virtual axis. Then, operators can adjust the phase relation to advance or retard as needed by manually adding an MAJ or MAM on top of the current ...

RE: Motion Tracking Error At Higher Speeds

Yes, if both motors were synchronously coupled and could not accumulate error the virtual master is ideal. I've used that with great success, unfortunately this application is not synchronous and will not work with that design. Thanks! - Austin ------------------------------ Austin Adams ------ ...

Correct, a V-Belt application and we cannot change that part. Ideally it would be a synchronous coupling and in those applications I have used a virtual master with both motors slaved to that and then they physically stay synchronized perfectly over the speed range since their position errors grow at ...

I am interested in a way to reduce the tracking error in a CIP motion application. The system has two PowerFlex 755 drives operating in CIP motion. The master axis is connected via a non-synchronous belt to a press. Attached to the press is an 842E motion encoder, which the slave axis tracks via a MAG ...

VPC Control With Powerflex 755

Summary: Can a Powerflex 755 control a VPC servo motor in an electronic gear configuration? I'm looking for a solution to synchronize a servo motor to a master encoder. The servo motor is fairly large (22kW) and an MPL motor did not match all the needed specifications. I know a 5700 drive is ideal ...
