This function is useful in case of mechanical structures, whose movements are subject to strong frictions.
If the axis does not return to the threshold within the specified time, the control unit generates a Warning and
not a serious alarm condition.
•
Set the MaxPosTime parameter with a value lower or equal to the one set in MaxStatErr.
•
Set the MaxPosTime parameter with the time value, in seconds, allowed to the axis to return to the
threshold stated in the previous point.
5.1.3.18. Automation of the zero cycle procedure
In order to automate, at the start, the zero cycle procedure without having to send the specific command, set
the parameter Type Cycle0 = 3.
5.1.3.19. End of the operations
•
Take the control unit to the IDLE status.
•
Save the parameters in Flash.
•
Save the parameters on a file.
