Stepper output ATYPE=43
The position profile is generated and the output from the system is
a pulse train and direction signal. This is useful to control a motor
via pulses or as a position reference for another motion controller.
Servo axis ATYPE=44
fig. 35
With
SERVO = ON
this is an axis with an analogue speed
reference output and incremental encoder feedback input. The
position loop is closed in the TJ1-MC__ which sends the resulting
speed reference to the axis.
fig. 36
With
SERVO = OFF
, the position of the external incremental
encoder is read. The analogue output can be set with BASIC
commands only and can be used for general purposes.
