Block change performed as quickly
as possible with immediate block
change.
After the programmed deactivation
position that refers to the machine
coordinate system has been
crossed, the block change is not
enabled until the deactivation
positions POS have been
FS
crossed.
Value range 0 ... 359.999 degrees.
The block change is enabled
immediately.
The block change is enabled
according to the defined setting.

activation of
synchronous
operation
with any
angular
reference
between the
leading and

Activation
with a
defined
angular
offset POS
FS
between the
following and
leading
spindles.
This offset is
referred to
the zero
degrees
position of
the leading
spindle in a
positive
direction of
rotation.
