The drive is stationary after it reaches its target position.

0 Signals the completion of a traversing task or standstill for
intermediate stop and stop.

Within the traversing block/
1 Within the traversing block
A traversing block is active.

outside the traversing block
0 Outside the traversing block
No traversing block is active.

load power supply failed
0 Load power supply failed
This corresponds to the ”undervoltage” fault
Note:
When an undervoltage condition is detected, the appropri-
ate fault is signaled and ZSW.15 is set to ”0”.
S Before SW 1.3 the following applies:
ZSW.15 is set to ”1”, if, when acknowledging the fault,
an undervoltage condition is no longer detected.
S From SW 1.3, the following applies:
ZSW.15 is set to ”1” if an undervoltage condition is no
longer detected.
The fault itself remains until it is acknowledged.
ZSW.15 indicates the status of the load power supply,
independent of the fault and acknowledgment.
The block number of the actual traversing block is entered into this
status byte.
If no block is active, then the block number of the selected traversing
block is signaled back, i.e. the block which should be the next block to
be started.
The programmed block components ”MMStart”, ”MMStop” and
”MMPos” corresponding to the program sequence are output in this
status byte.
This means that the master has information about programmed block
for additional processing and evaluation.
Checkback signal (feedback) of the terminal status (from SW 1.4), refer
to Chapter 5.5.10
