Digital Brushless AC Servo Drive system - Ref.1609 ACSD-15/80
Holding brake
FXM motors have an optional holding brake that applies friction to the shaft. Its purpose
is to immobilize or lock vertical axes, not to brake a moving axis.

The characteristics depending on the type of brake are:

Nota. The maximum speed is 10000 rev/min, for all of them except for the brake that
may be used on the FXM7 series that is 8000 rev/min.
WARNING. NEVER use this holding brake to stop a moving axis!
WARNING.
The holding brake must never exceed its maximum turning speed.
A voltage between 22 and 26 V DC releases the shaft. Make sure that
no voltage over 26 V DC is applied that prevents the shaft from turning.
When installing the motor, make sure that the holding brake fully
releases the shaft before making it turn for the first time.
