NEGLIMIT indicates the Negative position limit Negative position limit Negative position limit Negative position limit for
Negative position limit
all movements. If this value is exceeded then an
error is triggered. NEGLIMIT is only active if
SWNEGLIMACT (19) has been set.
If a positioning command is entered which
exceeds the limits set, then it is not executed.

HOME_VEL determines the Home velocity
which the movement to the reference switch is
made. The velocity statement refers to the rated
speed and depends on the VELRES (22) parame-
ters. Generally this statement is made in % of the
rated speed.

A negative sign means the search will

rotation (depending on sign) this should be set at
the limits of the motion area. Only in this manner is
it possible to guarantee that the drive actually
moves towards the reference switch when moving
home and not away from it. In order to maintain a
good repeatability of the reference motion no more
than 10% of the maximum speed should be used.
