Procedure for Manual Reference Position Return Operation

1 Press the reference position return switch, one of the mode
selection swithces.
2 To decerease the feedrate, press a rapid traverse override switch.

3 Press the feed axis and direction selection switch corresponding to the
axis and direction for reference position return. Continue pressing the
switch until the tool returns to the reference position. The tool can be
moved along three axes simultaneously when specified so in an
appropriate parameter setting. The tool moves to the deceleration
point at the rapid traverse rate, then moves to the reference position at
the FL speed set in a parameter.
When the tool has returned to the reference position, the reference
position return completion LED goes on.

4 Perform the same operations for other axes, if necessary.
The above is an example. Refer to the appropriate manual provided by
the machine tool builder for the actual operations.

NCPLUS compiler

NCPLUS compiles a user program and produces a machine code file, instead of interpreting each block while cutting. That means that all syntax and typing errors are detected before the actual cutting begins.

In addition, it takes less than 25 micro-second to process a block, while other high speed control builder are proud with 1 msec for the same. (Test conditions: 300 MHz Pentium, sequence of blocks with N and X,Y,Z)

The time is saved because the compiler translates decimal numbers into binary format and replaces all Goto line numbers with absolute memory addresses.
