Smithy Ez-Trol2 - Manual (Page 42)

5 FEED OVERRIDE
EZ-Trol allows the operator to adjust the feed rate up to 120% but it cannot adjust the feed rate at a
percentage that would increase the rate beyond the machine’s recommended maximum setting. For
instance, if the operator wanted to move the X-Axis from one limit to another and a continuous
movement of speed had been selected that was set at a feed rate of 0.25 inches per minute, the
operator may want to increase the feed rate. To override the feed rate, reposition the slider until
you have reached the desired feed rate. A value can also be entered into the Feed Override field as
long as the value doesn't exceed the maximum feed rate of 120 inches per minute, which is set by
the factory.
6 JOG SPEED
The operator can adjust the speed of axial movement while jogging either with the slider below “Jog
Speed” or by entering a value in the field next to the “Jog Speed”.
7 SPINDLE SPEED CONTROL
The operator can also adjust the spindle speed from the manual screen by moving the slider from
left to right, which adjusts the spindle speed control by a percentage of the current speed setting.
The operator can also set the spindle speed by entering in a value in the field directly after the
Spindle Speed Control wording. Spindle speed cannot be set beyond the maximum default speed
range of the machine tool that is being operated.
8 E-STOP
The E-Stop in the manual mode is used to stop the machine in cases of emergency while the
operator is manually jogging the machine axes. Before starting manual jog moves remind yourself
that the E-Stop is available and note it’s location for easy recall as needed. When selected it will
turn red and all power to the machine will be cut. You will need to reposition the axes when the
E-Stop has been pushed.
9 ON
This button switches the machine back on after turning it off using the E-Stop button.
10 ABORT
Abort works in a similar fashion to the “Abort” function in the Auto mode. When Abort is clicked
all action will be stopped but position will not be lost. There are situations where the Abort button
is helpful. For example, if continuous feed has been selected and the operator decides to move the
table 0.5 inches but accidentally types in 5.0 inches. He would certainly quickly notice that the
machine has moved past the 0.5 inches of desired movement and clicking on the “Abort” button can
stop this action.
11 FEED HOLD
Feed Hold works in a similar fashion as the Feed Hold in the Auto mode. When the Feed Hold
button is clicked, all movement will be “paused” but the machine will continue to be “energized”
and the spindle will continue to rotate. The button will turn green when the Feed Hold button is
engaged. Clicking again on the Feed Hold button will resume axial movement through to the
completion of the part program.
