Operating Controls; Power Switch; Remote Switch Box; Variable Frequency Drive (Inverter) - Powermatic PM2014 Operating Instructions And Parts Manual

9.0 Operating controls

9.1 Power switch

The toggle switch atop the inverter turns on/off
power to the lathe. The holes in the flanges allow
insertion of a padlock (not included) for additional
safety. See sect. 1.1.

9.2 Remote switch box

See Figure 9-1.
The switch box has a magnetic base, and may be
conveniently placed anywhere on the lathe body.
(A) LED Readout: Displays spindle speed when
lathe is operating. Displays indexing position when
lathe is stopped and index button (E) has been
pushed.
(B) Spindle start/stop: Push green button to
activate spindle; red to stop.
(C) Spindle direction: Can be activated while
spindle is turning – spindle will automatically slow to
a stop before reversing direction.
When turning with a face plate,
make sure both set screws on the face plate are
tight (see Figure 8-7) before reversing spindle.
Failure to comply may cause face plate to spin
loose from spindle.
(D) Speed control dial: Always start Lathe at
lowest speed, with dial rotated all the way counter-
clockwise.
(E) Index button: Push to set index reference to
zero. See sect. 8.5.

9.3 Variable frequency drive (inverter)

The PM2014 Lathe uses the latest technology in
A.C. inverter drives to provide infinitely variable
spindle speeds within the specified ranges. The
inverter controls the speed of the motor by varying
the frequency of the voltage supplied to the motor.
The inverter provides an acceleration ramp that
eliminates the shock of normal starting.
Also, a braking feature eliminates long coasting
periods after the Lathe is turned off.
The A.C. Inverter does not require any programming
– it is pre-programmed by the manufacturer. Use
only the controls on the switch box to operate
lathe.
If an inverter error occurs, the LED on the switch box
will show "Err". Contact Powermatic technical
service at 1-800-274-6846.
surge may cause the inverter to fail. When lathe
is not in use, disconnect power plug, or have a
3-pole disconnect installed on the power side.
