T
he actuator must be integrated with the main control system in one of two
ways:
•
Directly to the main control system. In this case it is important to
consider the communication protocol.
•
Through a stand-alone sub-system delivered by Eltorque. This is a
standardized hardware and software platform tailored for Eltorque
actuators.
The solutions illustrated below show a bus connection with the Eltorque
Hybrid Marine Cable. This cable can be used with the CANopen and Dual
Caution!
Remember to have the actuator checked by Eltorque after all submerged
