10.2 Inverter (PM-2X4SP only)
The inverter on the model PM-2X4SP maintains
spindle speed. The display shows frequency; turn
knob to adjust. See Figure 10-2. Multiply number on
display by 60(Hz) to identify spindle RPM.
Figure 10-2
The STOP button will stop the spindle during
operations. However, it is recommended that any
process be stopped using the controller, instead of
the STOP button on the inverter.
10.3 Operating procedure
Operations may be done manually, through the
controller keypad, or automatically, through the
design file downloaded through the controller via U-
disk or internal memory.
1. Make sure levelers beneath stand have been
lowered to floor to prevent machine from rolling.
2. Make sure workpiece is secured to table using
clamps or double-sided tape.
3. Release E-stop button by rotating clockwise.
4. Turn on machine by rotating green switch. The
controller will also turn on and display screen
will light up. Allow system to completely boot.
NOTE: The machine must be homed before
performing any other function. See sect. 10.3.
5. In Home position, head will be in accessible
position to insert cutting bit. Switch off
machine and install bit securely in collet.
Restart machine.
Note: During gantry movement, observe drag
chain beneath table. If it has tendency to catch
on cross brace, lift it slightly to clear.
10.4 HOME position (machine origin)
When machine is started, controller display will
show prompt requesting Home (Figure 10-3).
Figure 10-3
Home position is determined by actual limit switches
on the machine, and will not change. However, it is
important that the machine be homed before
each distinct operation to ensure that settings and
limit switches are properly functioning. All
movements are based upon these Home position
limit switches.
1. Press HOME. Spindle will move to Home
position, generally front left corner of table.
2. Press OK and spindle will move to work origin.
(see sect. 10.6 to set work origin).
After normal shut-down of the machine, if you start
up and continue the previous operation, homing will
not be necessary as the system will have saved the
last coordinate values. Select “none axis home.”
10.5 Moving router head
Router head can be moved manually in one of 3
ways. Press MODE to toggle between selections.
The system uses a grid, or minimum feed, concept
to assist processing accuracy. The range is 0.05mm
to 1.0mm. In continuous or step mode, the router
head will move to next grid if button is toggled.
1. Continuous mode: Hold down X+/-,Y+/-, or Z+/-
button and head will move until button is
released. Screen displays location of router
head as it moves. If button is held less than 1/2
second, machine will move to nearest grid.
HIGH/LOW button determines speed of
movement. Machine will always stop on grid at
end of continuous motion.
