Drive controller
Digital AC servo drives are intended for use in secondary control loops.
With the digital AC servo drive with ANALOG interface, this is achieved
by forward feeding an analog voltage signal through an associated NC
control.
Risk of personal injury and machine damage through uncon-
trolled drive motions. Operating an AC servo drive in anything
other than a secondary control loop runs counter to the pre-
scribed use for this equipment. Should this still be desired,
special safety precautions must be taken. These are explained
in Section 6.6.
If a Digital AC servo drive is to be operated without an NC control, this is
possible in velocity loop mode using a battery power source to be
connected up as illustrated in Fig. 30. The procedure for operating a
servo axis is described in Section 6.6.
