Hi Mi Qingru,

The motor record has a field called .STUP, If you write a 1 to that field it will update the motor status.  This works with any motor driver.  So you could configure a bo record with SCAN=1 second that writes to the .STUP field for example.

For the older "Model 1" motor drivers, which have separate device and driver files for each controller type, this is the only way to do it.

For the newer "Model 2" and "Model 3" drivers you can also configure the driver to periodically do callbacks to the motor record.  There are two configurable callback rates: a fast one when any axis on the controller is moving, and a slow one when all axes are idle.  For these drivers you do not need to write to the .STUP field.

The MAXv has both an old Model 1 driver and a new Model 3 driver.  You can chose which you want to use.  I think the PI C863 only has a Model 1 driver, but I'm not sure.

MAXv and PI C863 all need this function. Now we apply motor R6-7.

You need to tell us what motor driver you are using.  OMS58, MAXv, Newport
XPS, etc.  And what version of the motor module?

Hi all,
    I need to update motor status and position periodically as it has no
motion. If can I only change the wait_time from 1000s to other period such
as 5s in motor_task ?
