Installation
Terminal
Data for control connections
(printed in bold = Lenze setting)
CAN_GND
CAN earth ground
For reliable communication make sure terminal
CAN_GND is connected to CAN network
GND/common. If only two wires are used (CAN_H
and CAN_L) in the network, connect CAN_GND to
chassis/earth ground.
CAN_L
CAN low
If controller is located at either end of the network,
a terminating resistor (120Ω typical) should be
connected across CAN_L and CAN_H
CAN_H
CAN high

Protection against contact
•
All terminals have basic isolation (single insulating distance)
•
Protection against contact can only be ensured by additional measures (i.e. double insulation)
