6 Intended Use
See also section 2.3
6.1 Guidelines for Application

Only for use as holding brake with a limited num-
ber of EMERGENCY STOP braking actions. Not
suitable for cyclic STOP braking actions in cycle
operation.

Please observe the correct dimensioning of
speed, braking torque, friction work and switching
frequency in case of EMERGENCY STOP for
safe holding of the load torque and safe compli-
ance of the required braking distance and over-
travel time.

The stated switching times can only be achieved
using the respective correct electrical wiring. This
also refers to the protection circuit for brake con-
trol and the response delay times of all control
components.

The brake is designed for 120 °C. Temperatures
above 120 °C in machine use can reduce the
magnetic force. Brake does not release properly.

Application in clean environments (penetration of
coarse-grained dust and liquids such as oils can
have a negative effect on the braking function).

Application in enclosed buildings
(In tropical regions, in high humidity with long
downtimes and sea climates only after taking spe-
cial measures).

power transmission.
Brakes which are to be used in safety-re-
lated applications must be selected, di-
mensioned and positioned according to the
risk assessment DIN EN 12100 and other
standards and regulations applicable to the
special application. This is in principle the
task of the system manufacturer/user.
6.2 Limits

The brake is not suitable for use in oily or se-
verely contaminated environments
6.3 Reasonably Foreseeable Misuse
The following uses are prohibited and may generate haz-
ards.

Any opening of the screws on the housing.

The maximum switching frequency is exceeded

Brake is used in oily or heavily contaminated sur-
roundings

The overexcitation time, see Chapter 5.2.6, is ex-
ceeded or undercut.

No overexcitation
6.4 Duration of Use
20 years or on reaching the T10d (for definition, see EN
ISO 13849-1) duration of use.
6.5 Dimensioning
Attention!
When dimensioning the brake, please take into consider-
ation whether a load torque is present when selecting the
protection.

Load torques reduce the deceleration torque availa-
ble.

Load torques may increase the output speed:

during a possible processing time in the
controls

during the brake downtime
When calculating the friction work, please observe that
the brake nominal torque is subject to a tolerance.
