NOTICE
In case of travel axes, the compliance of the permissible rao of mass inera load/brake
motor (J
L
/J
MB
) ensures that the permissible maximum switching energy of the brake will not
be exceeded and at least the values given for the emergency stop funcons from the given
speed (see rated data) are applied.
For hoist axes, the load torque resulng from the weight acts addionally. In this case, the
specicaons for (J
L
/J
MB
) do not apply.
To simplify maers, the fricon energy per switching cycle can be calculated using the formula
below and must not exceed the limit value for emergency stops, which depends on the
switching rate:

The shortest operang mes of the brakes are achieved by DC switching of the
voltage and an external suppressor circuit (varistor or spark suppressor).
Without suppressor circuit, the operang mes may increase. A varistor/ spark
suppressor limits the breaking voltage peaks. It must be ensured that the power
limit of the suppressor circuit is not exceeded. This limit depends on the brake
current, brake voltage, disengagement me and the switching operaons per
me unit.
Furthermore the suppressor circuit is necessary for interference suppression
and for increasing the service life of the relay contacts (external, is not
integrated into the motor).
It is not possible to readjust the brake.
