5.3.2 Dry Run
General
A cutting command in the program is executed using the feedrate
specified in a parameter. This function is used, for example, to check
only the movement of the tool with no workpiece mounted. By
parameter setting, the user can choose whether to use the dry run
feedrate for the rapid traverse, threading, and tapping commands as
well as cutting commands. The tables below indicate the dry run
feedrates that are actually used.

Signal
Dry run signal
DRN<G004#1>
[Classification] Input signal
[Function] Enables dry run.
[Operation] When this signal is set to 1, the tool is moved at the feedrate specified
for dry run.
CAUTION
When the dry run signal is changed from 0 to 1 or 1
to 0 during the movement of the tool, the feedrate of
the tool is first decelerated to 0 before being
accelerated to the specified feedrate.
