Data word Name Direction Type of signal

000.00 EMERGENCY STOP PLC → NC static

0 = emergency stop state

1 = normal operating state

Effect in the NC: The 0 signal interrupts all movements, the program process

is interrupted.

Data word Name Direction Type of signal

000.01 Feed enable (total) PLC → NC static

001.00−15 Feed enable axis 0 ... 15 PLC → NC static

For each axis a "Feed enable" signal is output. There is also a common enable

signal. The resulting feed enable is created as a logic AND operation with the

axis−dependent feed enables.

Signal state "1" activates feed enable.

Effect in the NC: The "1" signal enables the respective axis to move if the

"Feed stop" signal is not set.

A "0" signal stops the respective axis or all of the axes. Moving axes are

stopped with the set deceleration ramp.

In the case of interpolation, all of the participating axes are prevented from

approaching, or they are decelerated if feed enable is rejected for one of the

participating axes.

In manual operation, the traversing commands are interrupted, i.e. after the

feed enable is restored, the command must be given again in order to conti-

nue.

In automatic operation, the movements are only interrupted, the traversing

command continues as soon as the feed enable is restored.

Data word Name Direction Type of signal

000.02 Quick stop PLC → NC static

A common signal for all axes:

0 = The movement of axes is enabled.

1 = Moving axes are stopped withoutdeceleration ramp ("quick stop").

Effect in the NC: The "1" signal causes the moving axes to stop without dece-

leration ramp. The movements are only interrupted and the traversing com-

mand continues as soon as the signal is reset to 0.

Application: Response to "Emergency stop" in applications, which require

the program to continue after an emergency stop. In this case, only the feed

enable is canceled by the PLC. If the axes should still stop abruptly, you can

set the "Quick stop" signal beforehand.
