Dangerous
movements!
Danger
to
persons
from
falling
or
dropping
axes!
The standard motor holding brake provided or
an
external motor holding brake
controlled directly by the drive controller are not sufficient
on
their own to guar-
antee
personal safety!
Personal safety must
be
achieved using higher-level, fail-safe measures:
• Block off danger zones with safety fences or safety guards
• Additionally secure vertical axes against falling or dropping after switching
off the motor power by, for exampl
e,
mechanically securing the vertical axes
adding external braking/arrester/clamping mechanisms
ensuring sufficient equilibration of the
vertical axes
Function
The connection point X6 contains the connections for
• monitoring the motor temperature
• controlling the motor holding brake
~
Via
an
integrated contact element (BR), the power section switches
the
voltage of the
external
24V supply (connection X13 at HCS02
power sections) to the output for controlling the motor holding brake.

is
not available at the connection point X6 (see

below "Block Diagram of Internal Control Voltage"). There-
fore,
an
external
24V supply is required for controlling the motor
holding brake.
