Compax3 X13 Feedback port in DirectDrive F12 mode. What to do with the sense pins when the system does not have remote sense?

parkerhannifin@janbeck.com
By  parkerhannifin@janbeck.com 7 months ago

The datasheet for the Compax3 drive available here: https://www.parker.com/literature/Electromechanical%20Europe/User%20Guides/C3S%20paper%20eng.pdf

documents the pinout for the X13 connector when used in the F12 mode. The sense +/- pins seem necessary only to correct the 5V supply over long cables. When using short cables and an encoder that does not have sense capability, what should be done with these pins? Floating? Connected to 5V/Gnd on drive?

Also, what kind of signal is this when sense is supported? Is this simply 0V and 5V at the encoder sent back to the drive?

Thanks

    Good afternoon.  The good news for short cables is that you can leave those sense lines unconnected and the cable will work just fine.

    If you wanted to make use of them for a long cable (say, 50 m), you would just need to make sure you have two spare conductors in your cable.  You would connect one of the conductors to Sense+ and the other to Sense-.  Then, at the motor end, you would solder both conductors together inside the connector.  Neither one actually connects to the encoder.

    The Sense lines effectively just allow the Compax3 to measure cable resistance (proportional to length) and estimate voltage drop so that it knows how far it needs to boost encoder supply voltage to make up the difference.  It is important to make sure the Sense lines use the same gauge that it used for all the other encoder lines so that they have about the same resistance.
