Motor holding brake (X8, X9B)
The motor holding brake can be controller by the servo amplifier. An external 24V supply
voltage delivers the required electrical power for the connected brake. Observe the
requirements to the supply voltage listed on page 27.
Serious injury could result when a suspended load is not properly blocked.

Feedback Systems
Every closed servo system will normally require at least one feedback device for sending
actual values from the motor to the servo drive. Depending on the type of feedback
device used, information will be fed back to the servo amplifier using digital or analog
means. Up to three feedback devices can be used at the same time.
S748/772 supports the most common types of feedbacks whose functions must be
assigned in the setup software DRIVEGUI.EXE with the parameters:
FBTYPE
EXTPOS
GEARMODE (screen page ELECTRONIC GEARING), secondary Feedback (ð p.83)
Scaling and other settings must always be made in the software. For a detailed descrip-
tion of the ASCII parameters, please refer to the

CAUTION
No functional safety!
An additional mechanical brake is required for functional safety, which must be
safely operated, e.g. via the Safety Card S1-2 (see p. 140).
