Virtual axis ATYPE=0

You can split a complex profile into two or more simple movements,
each assigned to a virtual axis. These movements can be added
together with the BASIC command
ADDAX
then assigned to a real
axis.
MECHATROLINK-II position ATYPE=40
fig. 32
With
SERVO = ON
, the position loop is closed in the Servo Driver.
Gain settings in the TJ1-MC__ have no effect. The position
reference is sent to the Servo Driver.

are updated, the real value is
the value in the Servo Driver. The real Following Error
can be monitored by the

.
Note
The MECHATROLINK-II position
ATYPE = 40
is the rec-
ommended setting to obtain a higher performance of the
servo motor.
