The signal has the value "0" after the control has been switched on and if the
home position is unknown. The signal has the value "1" if the home position
of the respective axis has been approached or if value −1 has been entered for
machine constant MK_REF_RICHTUNG_UND_FOLGE for the respective axis.
Effect in the PLC: Checking the home position approach and disabling ma-
chine functions or traversing movements (feed enable) if the home position
is not approached.

The signal has the value "1" if the homing of the respective axis is currently
running.
Effect in the PLC: Checking whether the home position approach of an axis
is currently active.

Operating mode
NC

PLC
static
The operating mode word shows the PLC the operating mode selected by the
operator, in which the NC control is at present:
0 = initial state; no axis movement possible
1 = set−up
2 = set−up functions: modal traveling, step travel, zero points
3 = automatic, autom. processing of programs (individual block, following
block)
4 = programming
80H = diagnostics (DW131.7)
The operating modes are preselected by the operator. If Lenze’s MMI is used,
the selected submodes are stored in the DB2 in DW128.
Effect in the PLC: operating mode−oriented enable or disable.

Value "1" of the signal indicates that the processing of an NC program or a
traversing block ("Manual individual block") is active. The signal is pending
until the end of the program (M02, M30), program termination ("NC pro-
gram stop") or internal termination due to an error, which cannot be reme-
died, or the end of a block or block termination (manual operation).
Effect in the PLC: Evaluation for disable, synchronization, time measure-
ment.
