Stragne motion with V2.04

Hello,

what is changed with motion in V2.04?

After updating from v1.20 nohting is working right anymore.

Doing commissioning with CtrlX or Drive, everything seems to work. But when doing movements with PLC it's strange.

The drive should do a cycle with right/left turning. Speed right 1000 rpm for 3 turns, left 1000 rpm for 6 turns, acceleration/deccelaration 30 ms. This is via a PLC program.

With drive oszi it looks this:

green = speed

First, acceleration is as should wihtin 30ms to target speed 1000 rpm. But then, braking, going left, going right, going left, stop.... Normally it should look like a positive trapezium, then a negative one.

When doing jogging (via own PLC program) acceleration is not what it should be. It's imited in any way. But deccelartion is working right.

Code is that, using Jog-Mode:

Did another test with Vel-Mode:

Now acceleration is working right but not decceleration, code is that:

All limits in CtrlX are high enough that they don't bother:

And there are no limits in drive (except speed):

And no issues with any status reports from drive:

That's the way it worked with v1.20 and before.

What's different with v2.04?

Good news this issue will be solved in the version 2.6 coming up end of march. Please test again with this version and come back if there are open topics.
