Function : Waits until the specified stop condition is fulfilled. Does not run the spindle while waiting.
Type Parameter Function
Time Time The step waits the specified time
PLC The step waits until a positive edge of one
of the PLC Station Variables START or
INTERMEDSTART is detected
Digital
Input Digital input .
Local DI 1, … Local DI 4
PLC_DI_1, … PLC_DI_10
DI Spindle def.
Stop Condition :
Falling Edge, Rising Edge,
Any Edge, Low or High
The step waits until the selected digital
signal fulfils the condition selected in
Stop
Condition
Continue The step waits until all other bolts running in
parallel have reached the next
synchronization point.
If the check box Hold Position is checked, the spindle tries to hold the position of the bolt
during the wait. The position will be held until the next step starts, if there are any delays
between the steps due to synchronization the position will still be kept.
