Temporary Stop; Single-Block Operation; Machine Lock Operation - YASKAWA MOTIONPACK-110 Descriptive Information

3.5.2 TEMPORARY STOP
If temporary stop signal (STP) is turned on while the system is executing a program, the
machine stops after deceleration, and the program is restarted when this signal turned off.
For ON-OFF operation, use the maintained contact.

3.5.3 SINGLE-BLOCK OPERATION
In this mode, the program is executed one block at a time. When a single-block signal
(SBK) is turned on and a start signal (STR) is turned on, the machine executes one block of
the program and stops. When'another start signal is turned on, the next block is executed.
When a single-block signal is turned on, while the system is operating continuously,
the current block is executed, and the system stops. When the single-block signal is turned
off, and subsequently, a start signal is input, the operation will be executed in the
continuous mode.

3.5.4 MACHINE LOCK OPERATION
When a machine lock signal (MLK) is turned on, and then, a start signal (STR) is turned
on, the current position display starts to change as if the machine were executing the
program, but the machine remains at a standstill. However, the M-functions, the
S-functions and the T-functions are executed. This mode is used, for example, when
presetting the display manually, or for checking the program. Note that while the machine
lock signal is on, the return-to-reference motion is not executed.
CAUTION
Be sure to turn on the machine lock signal only while the system remains
motionless after completely executing a block.
