Amada turret punches have diferent switches on a control board (in our case named VIP-11) which handle some output status. Particularly there is one switch called T.Align which turns off the hydraulic pump. Amada advises to leave it on the OFF position. The ON position means that the pump will be turned OFF if the Tool change switch is turned to ON (and viceversa).

What are the possible drawbacks of ignoring Amada´s advice and leave the T.Align switch on the ON position ? Having the pump working while changing the tools or loading a program to the CNC does not look like it is helping too much. Besides the noise of the pump is quite annoying.
