The servomotor is operated by a separate AC servo amplifier. This
is connected to the basic unit via two cables (not visible in the pic-
ture to the left).
The green power cable and the orange signal cable are connected
on the rear side of the amplifier box. Control of the servomotor
takes place via touch screen operating panel like the standard mo-
tor.
