when power off then power on the position change to 0,why?

hello everyone ,

i have a problem ,it is that :

when i power off the machine and then power on , one or two axis's position change to 0. i have to power off the machine again or more times .then the position will to be normal.why ?

and at the same time ,the axis have a warning :A01697 :ask me to test the safety monitoring.

please look the picture ,i am sure the remain time is not 0.but it shows 0. the others axis can be test stop selection by r2093.3 ,but this axis can't!.when i power off ,power on again ,when the position of the axis is normal ,then the test can do .why ?

thank you!

please help me !

why when i power off then power on ,the position of the axis will be change to 0?

You better define what kind of encoder you are mentioning at first. One reason could be the encoder is powered later then the interface and the synchronization of the component fail. Also the way you are writing about an absolute encoder. You may have a drive cliq interface or ET200S interface either.

Stop using my fantasy and waiting for more detail.

thank you  for  repling!

my encoder is absolute.

when the position change to 0  ,then i just power off  and  power on again ,then it may be ok.

WHY ?WHAT' WRONG?

Do you want to write what a hell of encoder you are mentioning?

is the encoder drive cliq hardwired and positioned inside of the servomotor or what?

 it's in the motor though drive-cliq.

Hello,

 

check the drive state after power On and Error -> if drive have any fault then the encoder date is not send to PLC.
On the axis check the Systemdata Axis.Sensordate[1].state, if this is not "Valid" then no encoder position is read from the TO.

 when POWER ON  there is  a warining  about  A01697, but the ohter axises can reset,only one axis can't reset.have to power off and power on again .

>>>  it's in the motor though drive-cliq.

seems like a guessing game. I get out.
