This counter is incremented by 1 for every rising edge by "NC program is run-
ning".

The signal always has value "1" when an axis is in motion or a command for
traversing the axis is active. Therefore, the signal also has value "1" if the mo-
vement of the axis has been temporarily interrupted by "Feed enable" or
"override=0". The signal is set to "0" after the target has been reached.

Effect in the PLC: Specific disables (e.g. in manual operation) while the axes
are moving.

The signal has value "1" if an axis has been started from the PLC, has reached
the target and the traversing command 110 is still pending in the traverse
key.

Effect in the PLC: The traverse key can be reset to zero.

The start signal is a byte information, which can assume a value between 0
and 255. A value greater than "0" is output if the information in the virtual
keypad of the NC has a value unequal to "0". The signal is pending for as long
as the information is pending in the virtual keypad. The information is divi-
ded in two half bytes (nibbles). The nibble with the higher value holds infor-
mation about the program type to be started; the one with the lower value
the mode to used for start−up. The information is defined by the MMI.
