Jogging With A Synchronized And Non-Synchronized Axis - Siemens SIMATIC FM 351 Installation Manual

Aborting Jogging
Aborting is a process with which the otherwise normal sequence of a target
approach is not carried out (see Chapter 2.2)
"Jogging" is aborted when:
Speeds
With the FM 351 jogging is possible at two speeds:
You specify the speed on calling the operating mode either in the parameter-
ization interface or in the FC JOG_MOD.
Limit for a Linear The limits for the Jogging operating mode differ for a synchronized and a
Axis non-synchronized axis.

If the traverse range limit is crossed during jogging:
The actual value display jumps to the opposite limit
and
The positioning is aborted.

Jogging at rapid speed.
Jogging at creep speed.
Jogging is positioning to target positions which are lo-
cated at a distance of the half target range from the soft-
ware limit switches.
The limits are determined from:
SLE–
linear axis
SLS+
linear axis.
If you do not previously release the key, the FM 351
terminates at a target point which is located at the half
target range in front of the corresponding software limit
switch. All ranges, which are necessary for correct ter-
mination, are set by the FM 351 at this target point.
Part of the working range in which no target position
may be located.
