Signal Output Commands; T-Function - YASKAWA MOTIONPACK-110 Descriptive Information

4.4 SIGNAL OUTPUT COMMANDS
These commands are for causing the machine (auxiliary machines, etc.) to perform
movements under programs. The commands are in two function types; T-function and
M-function.
4.4.1 T-FUNCTION
The T-function commands are used to designate tool Nos., etc.
(1) Command Format
Two digits following the code T designate T Nos. Leading zeros may be omitted.
TDD
[
) / T-designation number
(2) Output
Where a movement command and a T-command are programmed in the same block,
a BCD 2-digit T-code output signal (T,_ to T28) is output from the Motionpack to the
machine simultaneously with the movement command, and then, with a delay of t msec,
a T-code read signal (TF) is output. The delay time is set by a parameter #1100.
) (3) Completion Signal
The machine reads the T-BCD code output, and returns and MT completion signal
(FIN) to Motionpack. Then, the T-code read signal is cleared. It is also cleared by
a resetting operation or a mode change operation.
(4) Effective Range
However, the T-BCD code output signal (Tjl to T28 ) is not cleared when an MT com-
pletion signal is received, but is retained until a new T-command is received. This
means that T-code signals are modal, and remain effective after being used until a sub-
sequent T-command is given. Fig. 4.32 shows the time chart covering the above time
relationship.
(5) Related Signal (Travel Completion Signal, DEN)
Travel completion signal (DEN) is output after completing travel, when T code is
commanded in the same block as travel command. With T code only commanded, the
DEN is output With BCD code simultaneously. Selecting only the travel command does
not make any command.
The DEN is released by MST completion signal (FIN), resetting, or mode
changing.
