1.2 Protective Functions
1.2.1 Emergency Stop
Press the emergency stop button immediately if a problem occurs with the system or line. The
execution of all commands stops instantaneously when the emergency stop button is pressed.
Servo power supply of the PC NC is shut OFF and dynamic brake is applied to stop all mechanical movement. In the emergency stop state, the PC NC is in the alarm state “3002”. If the emergency stop signal is “opened”, the PC NC stops the entire operation, and the SVMX and BKX
signals are “opened”.
PC NC
This operation is executed by setting the pins on the board. The pins di ffer between J300M
and J100M.
Table 1.2.1.1 Emergency Related Signals
1.2.2 Overtravel
The overtravel function stops axis feed operation when an axis reaches the travel limit; for the
detection of travel limit, a limit switch and a dog are used and if an axis reaches the travel limit,
the limit switch outputs a signal and the function stops axis feed operation in response to this
input. The axis reached and stopped at the travel limit can be moved manually into the axis movable range.
When the overtravel input is “opened”, axis movement is stopped in the manner as indicated in
Table 1.2.2.1. In response to this input, the alarm output (ALM) is “closed” and the corresponding alarm message is displayed on the screen.
Signal Name Pin Setting

YASNAC PC NC Operating Manual Chapter 1: Outline of the YASNAC System
If the overtravel input is “opened”, select the manual mode (jog, pulse handle) and move the axis
in the direction opposite to the direction for which the overtravel input is “opened” to “close” the
input. After that press the [RESET] key on the NC operation panel, the alarm output and display
are canceled.
1. After the occurrence of an alarm due to the “open” of the overtravel input, the M, S, and
T code read output signals (MF, SF and TF) are not turned OFF.
2. If it is necessary to interrupt the operation called by M, S and/or T code, set the interlock
by an external sequence.
3. The alarm numbers at the occurrence of overtravel are 2001 to 2005. If the overtravel
alarm occurs, axis move is stopped. Note that the servo is not turned OFF.1
1.2.3 Stored Stroke Limit
To ensure improved safety in operation, this function prevents axis from entering the preset entry
prohibited areas both in manual and automatic operation.
(1) Stored Stroke Limit
To use the stored stroke limit function, the axis movable area is set by parameters with the
coordinate values in the machine coordinate system. The area outside the set boundary is
established as the entry prohibited area. If an axis enters the entry prohibited area, the function
stops axis movement and displays an alarm message. The function is made valid upon completion of the manual reference point return after the power is turned ON. In automatic operation, if even one axis causes the alarm, all axis are stopped.
In manual operation, only the axis that caused an alarm is stopped.

YASNAC PC NC Operating Manual Chapter 1: Outline of the YASNAC System
(2) Stored Stroke Limit B, C (G22, G23) *
The area either outside or inside the boundary set by parameters or by the commands in a
program is established as the entry prohibited area. The boundary is set with the coordinate
values in the machine coordinate system. Whether the entry prohibited area is established outside or inside the boundary can be determined by the setting for a parameter. The function is
made valid upon completion of the reference point return after turning ON the power.
