Problem with ModePos = 2, - absolute control.

Split from V90, how to configurate the SINA_POS_DB?.

Hello, please post in english. Here the translation from the internet for the others:

Hey, I have a problem with ModePos = 2, - absolute control. All other modes work only not those. not how to run it. I do everything according to the instructions. after EXECUTE on True the engine rotates in the position = 0, positioning does not change anything, still holds the position = 0. What do you do to set the absolute position?

Hello,

so did you home your axis? There is an output at the FB which shows you if your axis is homed or not. For absolute positioning it needs to be homed first.

Then you should be able. Do the following:

-Select Mode 2

-Give a Position at the input

-Give a Velocity at the input (also look that the overrides for velocity, acceleration and deceleration ar >0)

-then give a positive edge at "ExecuteMode" input

I'm sorry for the language. We managed to run,
 I did not have a set reference point using ModePos = 5.
 Is it possible to change the position in real time?
 I want the engine to keep track of the current position
 of the external encoder.

Hello,

I guess what you want to do is a kind of synchronism application. Following the position signal of an external encoder, is that right?

I need to mention that the basic positioner is not really made for such kind of applications. There are other applications specially made for synchronism. (e.g. DCB Basic Synchronism application)

But there is one operating mode in basic positioner which could help you. You need to change the MDI mode from edge triggered to continuous (p2649 = 1). Then the EPOS will always do a new positioning when the setpoint changes. The setpoint in your case is the actual position of the external encoder.
