6.10 X6.1 … X6.4, Motor Temperature Monitoring and Motor
Holding Brake
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 guarantee 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 switch‐
ing off the motor power by, for example,
– mechanically securing the vertical axes
– adding external braking/arrester/clamping mechanisms
– ensuring sufficient counterbalancing of the vertical axes
Function
The connection points X6.1 to X6.4 have an identical design. The identifiers
".1" to ".4" refer to the respective axis number.
The connection points contain 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 to the output for
controlling the motor holding brake.
