1.2Protective Functions

1.2.1Emergency 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”.

				This operation is executed by setting the pins on the board. The pins differ between J300M
		PC NC
				and J100M.
				Table 1.2.1.1		Emergency Related Signals
						Signal Name	Pin Setting
					Emergency Stop Input		CN12-19 pin on JZNC-JFC 10 board
						SVMX	CN12-17 pin on JZNC-JFC 10 board
						BKX	CN12-16 pin on JZNC-JFC 10 board

1.2.2Overtravel

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.

Table 1.2.2.1	Axis Stop Direction with Overtravel Input “Opened”
		Manual Operation Mode	Automatic Operation Mode
*+X to *+5		Movement in the *+X to *+5
input is “opened”		direction is stopped.	Movement of all axes is
*-X to *-5		Movement in the *-X to *-5	stopped in all directions.
input is “opened”		direction is stopped.

* Normally closed contact

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

1.2.3Stored 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.

G CODE	FUNCTION	GROUP
G22	Turning ON the stored stroke limit B	04
G23	Turning OFF the stored stroke limit B	04

Fig. 1.2.3.2 Stored Stroke Limit B Function

•In addition to the stored stroke limits A and B, stored stroke limit C can be added.

•With the stored stroke limit C, set the boundary of the area and inside or outside the boundary by parameters.

•According to the setting for the parameter or the input signal, one of the stored stroke limit C (third to fifth prohibited area) can be made valid.

•For details of the stored stroke limit B, C, refer to 4.2.3 “Stored Stroke Limit B and C (G22, G23)” in the PROGRAMMING MANUAL.

1.2.4Interlock Inputs

The interlock input is the signal used to disable axis movement, and is provided for each axis.

•When an axis is interlocked during movement, it is stopped after deceleration.

•When the interlock is released, the axis continues moving to complete the remaining commands. Upon completion of the commands, the program advances to the next block.

•For simultaneous two or three axis interpolation commands, interpolation operation is disabled if one of these two or three axis is interlocked.
