Check to tool knockout switches. The switches that show that the tool retension is unlocked. The problem is in the tool change cycle. The control is waiting for a finsh signal from a switch. The control has a amount of time it needs to see a signal that something happened. Also it could be the switch that tell the carasel is under the spindle. It is something in the first stages of your tool change cycle. The cycle should be in one of the owners manuals. I am guessing this is a fanuc control with a umbrella style tool changer.
