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