6. APPLICATION FUNCTIONS
6.23 Other axes start
6.23.1 Summary
The other axes start function is a function that automatically performs the start operation for other axes or turns
on/off the digital output signal according to the conditions for starting other axes (start conditions) and other
axes start data consisting of operation (operation content) that is performed when the conditions are satisfied.
When using the other axes start, set the other axes start data No. (1 to 32) to the other axes start specification
of the point table.
The start operation for other axes internally turns on the start operation signal (ST). Therefore, before the start
operation, set the operation mode and the point table for an axis for which the other axes start is performed.
This function can only be used in automatic operation and linear interpolation operation.
CAUTION
If the digital output signal is updated from the user program during controlling of the digital
output signal by the other axes start function, the consistency of the data may not be kept. This
condition is applied to the case when the host controller and position board update the data at
the same time to the same digital output area number. In this case, read/write the digital output
signal after controlling the possessory right of the digital output signal using the exclusive control
function.
6.23.2 Settings
When using the other axes start function, set the following data.
POINT
When "1: Specified position pass specification" is set to the axis judgment
condition, a specified position opposite from the movement direction is judged
to be already passed, and therefore the condition is satisfied at the start
operation.
For tandem drive axes, set this function for the master axes. This function
does not operate when set to the slave axis. However, the slave axis can be
set as a observed axis.
