5.
Set depth stop for desired hole depth. Fine
adjustment is made by turning the fine adjustment
collar directly under pointer on depth rod. Use
upper jam nut to lock stop setting position.
6.
Start coolant, if coolant is being used.
7.
Turn spindle on and begin drilling operation.
As the breakthrough point is reached, always slow
feed rate down slightly to assist in elimination of
burring underside of workpiece and to help prevent
a sudden break through which can cause the drill to
grab and pull the workpiece free of its clamping
device.
8.
Perform all operations with a minimum
extension of the quill. Adjust table or head position
rather than using excessive quill travel.
9.
On tilting table models be sure to block the
part or holding fixture from sliding off the table
when it is used tilted at an angle. In addition, be
sure the table is clamped.
INVERTER DRIVE SYSTEM
The 1200HD Drill Press utilizes the latest technol-
ogy in A.C. inverter drives to provide the infinitely
variable spindle speeds. 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 across-the-line starting. Also a braking
feature eliminates long coasting periods when the
drill press is turned off.
The 2 HP Baldor motor is wound with "Inverter
Spike Resistant" magnet wire to give extended
motor life when used with inverter drives. The
motor is also specially balanced to reduce noise
and minimize vibration.
The A.C. Inverter does not require any program-
ming; it is pre-programmed from the factory. The
buttons on the face of the inverter should NEVER
be pushed at anytime. Use ONLY the controls on
the front of the head assembly.
POWER CONNECTION - ELECTRONIC
VARIABLE SPEED
The 1200HD Drill Press will operate on single or
three phase 230V or 460V, depending on inverter,
without any adjustments or programming. For
single phase power connect hot leads to R and S,
and for three phase power connect hot leads to R,
S and T as shown in the wiring diagram on page 22.
Remember to always connect the ground lead.
Before connecting to the power source make sure
the ON/OFF switch is in the OFF position and turn
the speed dial counterclockwise. If the switch is in
the ON position when the power is connected, the
inverter will trip out. If this happens, disconnect
power, turn switch OFF, wait thirty seconds and
then reconnect power.
NOTE: If there is a power outage while operating
the 1200HD Drill Press, turn the switch to the OFF
position, disconnect power source, wait thirty
seconds then reconnect power source and resume
normal operation.
FOOT SWITCH OPERATION
(OPTIONAL)
The optional foot switch (Figure 6) is used only for
reversing the spindle in tapping operations.
Before using the foot switch, place the control
switch in the FWD position. When performing a
tapping operation and the tap needs to be reversed
or retracted out of a hole, press the foot switch and
hold it down. The spindle will ramp down and
immediately reverse direction. Once the tap has
completely exited or retracted from the hole,
release the foot switch and the spindle will ramp
down and immediately return to forward rotation.
