Abstract
A method for determining an adapted master value of a master axis, wherein a setpoint slave value for a slave axis is derivable from the adapted master value via a synchronism function and a drive on the slave axis is operated in synchronism with the master axis based on the setpoint slave value, where the adapted master value is determined based on a base master value of the master axis and a time difference of operative times of determinable events on the master axis and slave axis.
Claims29
A method for determining an adapted master value of a master axis in an industrial automation system to increase an accuracy of a translation of a movement within the industrial automation system, the method comprising:
- operating a drive on a slave axis in synchronism with the master axis based on a setpoint slave value calculated for a subsequent interpolation cycle of the slave axis, said setpoint slave value being derivable from the adapted master value and being in relation to a base master value output by the master axis;
- determining the adapted master value based on the base master value of the master axis and a time difference of operative times of determinable events on the master axis and slave axis, said operative times comprising a system time which is common to the master axis and slave axis;
- and
- operating the industrial automation system based on the adapted master value such that the accuracy of the translation of the movement within the industrial automation system is increased.
A controller which controls a drive of a slave axis based on master values of a master axis in an industrial automation system to increase an accuracy of a translation of a movement within the industrial automation system,
- wherein the controller is configured to:
- operate the drive of the slave axis in synchronism with the master axis based on a setpoint slave value calculated for a subsequent interpolation cycle of the slave axis, said setpoint slave value being derivable from an adapted master value and being in relation to a base master value output by the master axis;
- determine the adapted master value based on the base master value of the master axis and a time difference of operative times of determinable events on the master axis and slave axis, said operative times comprising a system time which is common to the master axis and slave axis;
- and
- control the industrial automation system based on the adapted master value such that the accuracy of the translation of the movement within the industrial automation system is increased.
