information was sent, and the display will indicate the last line received. If an error
occurs, make sure that the letter O was not inadvertently used in the program
instead of a zero. Also see the “Troubleshooting” section.
When an RS-232 interface is used, it is recommended that the programs be written
in Windows “Notepad”, or another ASCII program. Word processing programs,
such as Word, are not recommended, as they will insert extra, unnecessary information.
Upload/Download functions do not need an axis select code as they are manually
initiated by an operator at the front panel. However, if the select code (Parameter
21) is not zero, an attempt to send a program to the control will fail, as the lines do
not begin with the correct axis select code.
HA2TS Setup and Operation (HA5C)
1. Position the tailstock so that the tailstock quill is extended between 3/4” to 1-1/4”.
This will optimize spindle rigidity (item A).
2. Tailstock to HA5C head alignment can be accomplished by pushing the tailstock
(item B) to one side of the T-slots prior to tightening the flange nuts to 50 ft-lbs. Precision
locating pins mounted on the bottom of the tailstock allow for quick alignment,
since the pins are parallel within 0.001” of the spindle bore. However, make sure both
tailstock units are positioned to the same side of the T-slot. This alignment is all that
is needed for the use of live centers.
3. Set the air regulator (item C) between, 5-40 psi., with a maximum 60 psi. It is
recommended is to use the lowest air pressure setting that provides the required
rigidity for the part.
Use of Collets, Chucks, and Face Plates
HA5C – The unit accepts standard 5C collets and step collets. When inserting the
collets, align the keyway on the collet with the pin inside the spindle. Push the collet
in and turn the collet drawbar
clockwise until proper
B
0.75
collet tightness is obtained.
Chucks and face plates
use the 2 3/16-10 threaded
nose on the spindle.
Chucks that are have no
more than a 5” diameter
and weigh less than 20
pounds are recommended.
Pay special attention when
installing chucks, always
make sure that the thread
and the outside diameter of
the spindle are free of dirt
