# Modal effect of changes in the cycle (P-CHAN-00210)

P-CHAN-00210 | Modal effect of changes in the cycle
Description | The modal G functions, circle geometry data and the current feed rate which are active before a cycle call are restored when the cycle ends, i.e. changes in the cycle with respect to this data are not retained. If the parameter 'cycle_changes_modal’ is assigned the value 1, changes in the cycle with regard to this data are retained after the cycle ends (modal). The cycle then responds like a normal subroutine with regard to effectiveness.
Parameter | cycle_changes_modal
Data type | BOOLEAN
Data range | 0: Changes of modal G functions, circle data and the feed rate in the cycle are effective only up to the end of the cycle (default). * 1: Changes of modal G functions, circle data and the feed rate in the cycle are also effective after the end of the cycle (modal).
Dimension | ----
Default value | 0
Remarks | * At the end of the cycle, only the types of modal G functions are restored that can be programmed on their own (e.g. G00, G01, G90, G91 etc.). G functions programmed in the cycle retain their validity in combination with value specifications (e.g. G129) or axis names (e.g. G92, G98, G99, G100, G112, G130 etc.).
