12 Handling of M, S, T, B Functions

12.1 Command Format

The following abbreviations are used in the subsequent explanations.
 Miscellaneous function (command) -> M function (command)
 Spindle function (command) -> S function (command)
 Tool function (command) -> T function (command)
 2nd miscellaneous function (command) -> B function (command)
 Miscellaneous function strobe 1 to 4 -> MF (MF1, 2, 3, 4)
 Spindle function strobe 1 to 4 -> SF (SF1, 2, 3, 4)
 Tool function strobe 1 to 4 -> TF (TF1, 2, 3, 4)
 2nd miscellaneous function strobe 1 to 4 -> BF (BF1, 2, 3, 4)
 Miscellaneous function finish 1, 2 -> FIN1, FIN2
 Miscellaneous Function Command High-speed Output: M function finish 1 to 4 -> MFIN(MFIN1,2,3,4)
 Miscellaneous Function Command High-speed Output: S function finish 1 to 6 -> SFIN(SFIN1,2,3,4,5,6)
 Miscellaneous Function Command High-speed Output: T function finish 1 to 4 -> TFIN(TFIN1,2,3,4)
 Miscellaneous Function Command High-speed Output: 2nd M function finish 1 to 4 -> BFIN(BFIN1,2,3,4)
12.1 Command Format
 The maximum number of commands that can be issued in one block are shown below.
Maximum number of com-
Function
mands(when released to user)
M function 4 commands
S function 2 or 4 commands (Form: Sn = xxxx)
T function 1 command
B function 1 command
 The command can have up to eight digits.
 The number of S functions depends on the model.
 A program error will not occur even if more commands than the maximum number are issued. The latter commands will be
valid.
(Example) When five T commands are issued though only one T command can be used.
T 01 T 02 T03
The last four T commands are valid.

12.2 Miscellaneous Function Finish

After the PLC (machine) finished the specified operations for the M, S, T, B commands output with automatic operation
(memory, MDI, or tape) or manual numerical commands from the CNC, the finish signal will be returned to the CNC. However,
there are two types of finish signals as shown below. Use these accordingly in one sequence.
 FIN1: CNC proceeds to next block at falling edge of finish signal (FIN1).
 FIN2: CNC proceeds to next block at rising edge of finish signal (FIN2).
The details for FIN1 and FIN2 are also described in the explanation of each interface signal.
Examples of the M function are given in the following section.
IB-1501668-B
T 04 T 05 ;
