The following are the different types of parameters on Okuma machining centers with OSP
5000/5020M series controls.
Common Variable
These programming variables have the same function as the common variables on lathes,
they are common to all programs. There are 128 on machining center controls and they
are labeled VC1 to VC128.
User Parameter
PROG LIMIT
These parameters contain the adjustable soft limits of the individual axes. In this menu,
the Work Coordinate value (WRK) and the Machine Coordinate value (MC) can be seen.
G60 OVERRUN AMT
The G60 overrun amount is the amount of travel the axis will overshoot when uni-
directional positioning is active.
BACKLASH
The backlash compensates for the lost motion on each axis when the axis feed direction
is reversed. The set backlash value is subtracted from the value read by the absolute
position encoder when the axis motion is reversed.
CLAMP IN-P
This parameter shows the clamp in-position width for each axis. If this parameter is set
to “0”, clamp in-position check is not carried out. If the axis moves out of this “window”
an alarm will be displayed on the CRT.
G/M Code Macro
These parameters allow the programmer to call up macros which contain sub-programs
that have specific functions.
MC User Parameter (long word)
These parameters are mostly positioning information about the APC or ATC. Up to 8
digits can be entered in these parameters. The decimal equivalent of these parameters
can be 5 digits or higher.
