E-stop, Start, Reset, and Power

Note: Before continuing, review Power Off/On Procedure later in this section.

E-stop (Emergency Stop)

Each mill has one Emergency Stop button or ‘E-Stop’ pre-installed on the Operator Panel (see Figure 1 and Figure 2). The E-Stop terminated all motion and Spindle Function. Depress the E-Stop and it locks in the Power Off position (see Figure 3). Turn the E-Stop clockwise a quarter turn to release; press the green Start button to power back on (see Figure 1)

Start

The green Start button powers on circuits for the axis drives. On the Operator Panel, the Machine LED indicates the green Start button is pressed (see Figure 2). When lit, the Machine OK LED on the PathPilot interface’s Status tab should be solid green (see Figure 4), indicating the mill is powered on and ready to operate.

Note: Once E-Stop is depressed, Start button is inoperative until the E-Stop is released.

Main Disconnect

The Main Disconnect switch, located on the right side of the electrical cabinet, is used to power the mill off and on (see Figure 1). When the Main Disconnect is switched to power Off, it disconnects the primary supply power to the mill. On the PCNC 1100, when the Main Disconnect is switched to power Off, it also disconnects the secondary supply power (to controller, monitor, and coolant outlets) from the Power Connection Panel.
