4.1 Mechanical Load Capability
The drive assembly of the LT360 consists of two aluminum castings
mounted between a 125mm (5In) ball bearing. The axial static thrust load
rating for the bearing is 8900 lbs (4000kg).
The load capability for the two castings depends greatly on how evenly the
load is attached to the castings. If the load is bolted properly and rigidly to
the surfaces, with the
weight concentrated in the
center region, the castings
should easily handle 1000
lbs.
If the load is not attached
to the platter and base
properly, than the castings
could fracture with smaller
loads.
Therefore it is critically
important that any jigs
being mounted to the
platter and base provide
their own rigid surface
strength to avoid excess
stress at the outside edges.

Error - 4 : RS232-BI Break Int Error
This error indicates problems with the serial port communications. It can be
caused by differences in the communication parameters between the
computer and the LT360. Make sure that the computer serial port setup is
9600 baud, 8 data bits, no parity, and 1 stop bit. If the LT360 baud rate has
been changed, then the PC must be set the same.
Error - 5 : RS232 Unknown Command
This error indicates that the character string sent to the LT360 did not
contain a valid command. This error will generally occur if you are writing
your own RS-232 program, and there are bugs in your program. Check the
command strings being sent to verify that they contain valid LT360 com-
mands. Case is not important, but spaces in the right or wrong places can
make a difference.
Error - 6 : RS232 Invalid Parameter
This error indicates that the LT360 was expecting a parameter value for this
command, but did not find one in the command string. Some commands
need parameters and some do not. This error will generally occur if you are
writing your own RS-232 program, and there are bugs in your program.
Check the command strings being sent to verify that they contain valid
LT360 commands and parameters. Case is not important, but spaces in the
right or wrong places can make a difference.
