Starting a Program with a Tool Already Active
You can begin a part program with a tool already active in the chuck. In
order for random tool to be able to properly handle that tool, it must enter
information about that tool in the random tool table.
Important: If you use random tool when the tool was loaded into the
chuck, it do not need to enter any data since random tool remembers what
tool is loaded even after power is turned off. This procedure is only
necessary if a tool is loaded manually or if random tool was not used when
the tool was loaded.
The control needs the following information to properly handle a tool that
is already active in the chuck. Tool number, number of pockets the tool
uses, and position of the shaft pocket relative to these other pockets (refer
to the section on manual entry of data for details on shaft pocket and
custom tool data). Do this in the following way:
1. Press the {ACTIVE} softkey. The control prompts you for the tool
number, the number of pockets, and the position of the shaft pocket
relative to the these other pockets all separated by commas.

2. The control displays the configuration of the tool that it thinks is
currently loaded into the chuck. If these values are incorrect, replace
them using the correct tool information. Enter a value for tool
number, number of pockets, and position of the shaft pocket all
separated by commas on the input line. Data can be edited on the
input line as described in chapter 2.
3. When the data for the tool that is currently in the chuck is correct,
press the [TRANSMIT] key. The control is now able to return the
tool that is in the chuck to the best location in the tool changer at the
proper time.
Important: You can also use the {ACTIVE} softkey to clear the currently
active tool and specify no tool is currently in the spindle. To specify no
tool is in the spindle press the {ACTIVE} softkey and delete any
information that appears at the prompt. When the [TRANSMIT] key is
pressed, the active tool is cleared and the random tool assumes no tool is in
the spindle.
