[SerialEncDataB Acc84E bits]

Thanks, this looks to be what I was after!

[SerialEncDataB Acc84E bits]

I'm looking to use it in a PLC (script language)

[SerialEncDataB Acc84E bits]

I'd like to have a shorthand way to look at the bits in SerialEncDataB, for example looking at the CRC bit etc.  I thought something like this might work, but it doesn't seem to.  Is there a good way to do this without having to do all of the bit shifting in a PLC?

 

#define LENC1CRC Acc84E[0].Chan[0].SerialEncDataB.22.1

[Position Compare with PFM Following Direct Micro-stepping]

Hello,

 

I am using direct microstepping on #1 of a GeoBrick LV and wish to use the position compare functionality as a trigger of sorts (in this case step as there is no encoder). I setup #5 as a virtual motor following the instructions for PFM so that I could use the position compare on #5 when it is following #1. The problem I am currently having is that #5 lags significantly behind #1 at higher speeds. I tried setting program acceleration and velocity to high values, the s-curve and accl-times to very small values for #5, and upped the PFM frequency, but I see no change in the amount of following error. Is there any other way to make #5 more synchronized with #1?

 

Thanks for your help,
