Rexroth IndraDyn A Application Notes 9-13
9.10 Motor Holding Brake (Option)
In normal operation, use the brake only when at a standstill and when
performing the drive-internal brake check. The motor holding brake is
required for holding the axes when the machine is in a de-energized state.
CAUTION
Hazardous movements! Persons endangered by
falling or descending axes!
Observe supplementary DIN and guidelines. For
European countries:
- DIN EN 954 / 03.97 on security-related parts of
controllers.
- Instruction sheet for vertical axis

The following is generally valid: the national
destinations must be observed!
he serially delivered motor holding brake does not
suffice to ensure personal protection!
Ensure personal protection by superordinate fail-safe
measures.
Cordon off the hazardous area by means of a safety
fence or a safety screen.
Additionally secure vertical axes to prevent them
from sinking or descending after having shutdown
the motor, for instance as follows:
- lock the vertical axes mechanically,
- provide an external braking / collecting / clamping
device, or
- ensure sufficient weight compensation of the axes.
- Miscellaneous suitable measures
The brake’s control mechanism must ensure this function in normal
operation. Under the worst-case load condition of the power supply, a
voltage of 24 V
DC
+/- 10% must be provided the motor brake. To identify a
failure in time during operation, the power supply for the brakes must be
monitored by an undervoltage detection system.
