10.1 TOOL SELECTION FUNCTION
For tool selection, an address T followed by a numeric value of no more
than 10 digits can be used to specify a tool number.
When a T code is specified, the code signal corresponding to the tool
number and strobe signal are output for tool selection on the machine.
This code signal is held until the next T code is specified.
Only one T code can be specified in a block. The maximum allowable
number of digits can be specified using parameter No. 2032, and an
alarm can be issued when a value greater than the specified maximum
allowable number of digits is specified.
