Danger of life or high damage to property, ig‐
nition and explosion hazard due to inappro‐
priate use!
WARNING
In order to prevent danger due to ignitable gases or explosive dust-air mix‐
tures in the vicinity of the motors, the user must make sure that the holding
brake does not present a source of ignition in the normal service. For this
reason, the holding brake must never be used outside the design parameters
and operating conditions (cf. standard EN 13463-1)!
●
When the motors are delivered, they are to be checked as regards an
ATEX-compliant marking subject to the application area, as regards the
accordance with the ordering details as well as for completeness and
any transport damages.
●
The holding brake integrated in the motor must only be used at standstill
and never as EMERGENCY STOP brake to stop the motor (n < 10
min
-1
) (intended use), see P-0-0119, "Optimal shutdown "(IndraDrive
firmware - functional description).
●
The holding brake must not be used to brake or stop the motor or cou‐
pled loads from higher speeds (n ≥ 10 min
-1
) or velocities (non-intended
use)
●
The voltage supply of the holding brake has to be designed so as to
guarantee under the worst installation and operation conditions that a
sufficient voltage is available at the motor in order to release the holding
brake.
●
The brakes must be designed so as to fulfill their function in normal
service, if they are installed and used as intended.
●
Commissioning and maintenance activities must only be carried out in
non-explosive environments.
Serious bodily injury due to dangerous move‐
ments caused by dropping or sinking axes!
WARNING
Secure vertical axes against dropping or sinking after switching off by e.g.:
●
Mechanical locking of the vertical axis
●
External brake, arrestor, clamping device.
●
Axis weight compensation
The holding brakes supplied as standard and controlled by the
controller alone are not suitable for personal protection!
Personal protection must be achieved by means of overriding fail-
safe measures, such as e.g. danger zones that are sealed off by
protective fences or protective grids.
In addition to the information and notes on the holding brake given here, ad‐
ditional standards and guidelines must be observed when designing the sys‐
tem.
