Connector assignment at X6
Both motor temperature and holding brake are monitored and controlled
by the drive controller. The are two possibilities to connect the lead to
terminal connector X6:
•
Use a motor power cable assembly manufactured by Rexroth
Indramat (recommended) or
•
Use two shielded lead pairs (motor temperature monitoring will not
function without a shield!).
Note:
Shielded leads are already integrated into Rexroth Indramat
cables for the motor temperature monitoring and the holding
brake devices. For detailed information, see the relevant motor
documentation.
Maximum cable length: 75 meters (Rexroth Indramat cable).
DANGER
Dangerous movements! Danger to persons
caused by falling or descending axes!
⇒
The standard equipment motor brake or an external
brake controlled directly by the servo drive are not
sufficient to guarantee the safety of personnel!
⇒
Make sure to protect the personnel by means of
primordial, safe measures:
- Secure the danger zone by means of a protective
fence or grid.
- Secure vertical axes against falling or slipping
after switching off the motor power by, for
example:
-
mechanically securing the vertical axes,
-
adding an external brake
/
clamping
mechanism or
-
balancing and thus compensating for the
vertical axes mass and the gravitational force.
