S7-1500T LCamHdl Test

Hello,

the overshoot is in the actual value, not in the command value.

Your drive couldn't follow the setpoint.

Use DSC (Dynamic Servo Control) and set Precontrol to 100%.

Optimise Drive and Positioncontroller.

Dear,

       Thank U for your help。

Hello,

the following error depends on the possible Kv and Kp and Tn of position and speed controller.

Kv and Kp and Tn depends on mechanical building, stiffness, ratio of inertia motor/load, controller cycle, precontrol, ..... .

It is difficult to do a correct simulation.

Important is a smooth setpoint profile, and a small IPO cycle in relation to cam cycle, to get enougth setpoints out of the profile.

Dear，

        Thank you, your answer, you said these I know, but can not understand is the simulation of this situation.

Hello,

Characteristics in simulation mode
An axis in simulation does not output setpoints to the drive and does not read any actual
values of the encoder. The actual values (Page 44) are formed with a time delay from the
setpoints.
Hardware limit switches and home position switches have no effect.
The technology objects measuring input (with signal detection via TM_Timer_DIDQ or
SINAMICS measurement sensing input), output cam and cam track can also be used for
axes in simulation.

If you want to simulate a whole machine you need additional tools.
