MC_Jog problem

[JHU1XI1]

Hello,

Why output Active?

Active:=TRUE;  Jog doesn't work.No alarm error.

It can only be used normally after resetting the PLC.

PLCopen Lib 1.18.0.2

Motion APP 1.18.2

Ctrlx works 1.18.1

Could you point out the order of what happened / you have done?

Is the axis powered on when/before input active is switched to true?

What is actual state of the axis before while and after using the function block?

[JHU1XI1]

The power on the shaft is normal, and the shaft is in the standstill state，

Jog is normal at first, but suddenly it is impossible to jog, and then Active is found to be true.

This happens occasionally at customers,

You might want to check the standstill windows in the drive in case the velocity dither (noise) is causing this function block to report that it is still moving.

I have reproduced this situation，

if MC_Stop.Exexute:=TRUE AND MC_JOG.JogForward ：=FALSE THEN

MC_JOG.Active:=TRUE,

No alarms will appear.
