7.1 General Technical Data
Brushless resolvers are outstanding for the industriellen application
under rough environmental condition suitably, there them to a large
extent insensitive to vibration, shock and increased temperature
stress are.
Outstanding features
� compact execution
� assembly directly on motor or drive shaft, no clutch
� no brushes or contacts
� no ball bearings
� compatibly with resolver / digitally transducer
7.1.6 Holding brake (optional)
To hold the axis without ply in standstill or while the plant is powerless,
the servo motors can be supplied with a holding brake. The
holding brake works according to the zero signal current principle
and is thus a safety brake. In currentless state a spring force acts
on the brake anchor disk, i.e. the brake is closed and holding the
axis. By applying 24 V DC, the spring force is lifted by the electric
field and the brake is opened.
DANGER!
Descending axes!
Persons run the risk of squeezing or cutting off limbs.
� The holding brake alone does not guarantee personal protection.
To protect people, provide for superior constructive measures,
e.g. protective grid, or furnish the plant with a second
brake.
CAUTION!
Holding brake may wear out prematurely!
Risk of personal injury!
� Do not use the holding brake for operating stop of a moving axis!
This is only admissible for EMERGENCY STOP situations.
The motors must not be operated against the closed brake. An
emergency stop of the motor (i.e., the brake drops while the motor
is running) is only admissible in exceptional cases.
