NOTE!
In the bimetallic power contacts of the thermal relay circulates direct current during the braking.
3.2.3.2.3 Output Connections
The output connections are done with the power cable and the feedback cable. The grounding of the power
cable shield must be done by using a metal clamp in models where it is available, as shown in
Figure 3.8 on
page 3-15
, or directly to the heatsink in models without the clamp. The grounding of the shield is intended to
minimize eventual radio-frequency interferences (RFI).

2 – Cable shield grounding (exposed metallic shield).
3 – Screw to fix the clamp on the cable metallic shield.
4 – Motor connection.
5 – Resolver Feedback connection (X2).

ATTENTION!
The characteristics of the cable used to connect the servo drive to the servomotor, as well as its
interconnection and routing, are extremely important to avoid electromagnetic interference in other
equipment and not to affect the life cycle of windings and bearings of the servomotors.
