3.3.1 Brake power supply
In all cases, the brake works with
uninterrupted voltage supplied by a rectifier
installed on the terminal box of the motor
supplied.
Two options are available for the alternative
sinusoidal power supply of the rectifier:
Power supply parallel with the motor
GB
power supply phases
This is the simplest and most common way
of using a brake.
In this configuration, it is not possible to set
up two-speed motors or use a motor with a
frequency converter.
Typical response times for the beginning of
the lock are:
F63-71 : 32 ms ; F80 :140 ms
Option: reduced response time.
Typical response times for the beginning of
the lock are:
F63-71 : 10 ms ; F80 : 35 ms.
3.3.2 Brake operating limits
The energy dissipated in the gasket over
successive braking cycles should neither
cause the brake to exceed the motor
temperature class nor lead to early wear.
Braking/hour, driving shaft inertia and motor
speed should be indicated when a motor
has to be chosen.
3.3.3 Adjustments
Unless otherwise stated, motors are sup-
plied with one of the braking torque values
specified in Chapter 4.5 (Performance Data).
However we have a procedure for adjusting
or replacing the gasket if this is required
during the use of the brake.

Independent power supply
The user must provide for an alternative
sinusoidal power supply (230 or 400V
± 10%). This connection also allows using
the motor with a frequency converter, but it
requires an additional cable gland.
Option: reduced response time.
