Introduction

 

CAUTIONS

 

This manual describes all the option functions (identified by the “*” symbol) but some of these may not be available with your YASNAC PCNC. To determine the option functions installed in your PCNC, refer to the specification document or manuals published by the machine tool builder.

Unless otherwise specified, the following conditions apply in programming explanations and programming examples.

lMetric system for input and metric system for output / movement

lZero point in the base coordinate system

lReference point

Yaskawa has made every effort to describe individual functions and their relationships to other functions as accurately as possible. However, there are many things that cannot or must not be performed and it is not possible to describe all of these. Accordingly, readers are requested to understand that unless it is specifically stated that something can be performed, it should be assumed that it cannot be performed.

Also, bear in mind that the performance and functions of an PCNC machine tool are not determined solely by the PCNC unit. The entire control system consists of the mechanical system, then machine operation panel and other machine related equipment in addition to the PCNC. Therefore, read the manuals published by the machine tool builder for detailed information relating to the machine.

1.2Protective 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 PCNC is shut OFF and dynamic brake is applied to

stop all

 

 

 

 

 

 

mechanical movement. In the emergency stop state, the PCNC is in the alarm state “3002”. If the

 

 

 

 

 

emergency stop signal is “opened”, the PCNC stops the entire operation, and

the SVMX and

 

 

 

 

 

BKX signals are “opened”.

 

 

 

 

 

 

PCNC

This operation is executed by setting the pins on the board. The pins differ between J300M

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

and J100M.

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 1.3. In response to this input, the alarm output (ALM) is “closed” and the corresponding alarm message is displayed on the screen.

* Normally closed contact

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.

YASNAC PCNC Operating Manual

Chapter 1: Outline of YASNAC System

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.

1.2.3Stored 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.

FIGURE 1.2.3.1: Stored Stroke Limit

YASNAC PCNC Operating Manual

Chapter 1: Outline of 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.

FIGURE 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.

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.
