Housing ground
Note the following information on the connection of the protective earth to
ground the housing correctly:
•
Note the assembly sequence:
•
1 M6 earth bolt
•
2 Contact disk
•
3 Cable socket
•
4 Washer
•
5 Return spring
(optional)
•
6 Nut
Contact disk, washer,
return spring and nuts are supplied with the drive controller.
•
Tightening torque: 4 Nm
•
Stray currents > 10 mA can arise in normal operation. To fulfill DIN EN
61800-5-1 and EN 60204-1, connect the earth bolts with a copper
conductor according to the following table:
7.2.3
EMC connection
•
Lay the power line, motor cable and signal lines separately from each other,
e.g. in separate cable channels.
•
Only use shielded, low-capacitance cables as motor cables.
•
If the brake line is carried in the motor cable, it must be separately shielded.
•
Connect the shield of the motor cable with large contact areas and in the
immediate vicinity of the drive controller. Use the EM6 EMC shroud to do
this.
•
Shield the cable for connection to a braking resistor if it exceeds a length
of 30 cm. In this case, connect the shield with large contact areas and in
the immediate vicinity of the drive controller.
•
For motors with terminal boxes, connect the shield to the terminal box with
large contact areas. For example, use EMC cable screw connections.
•
Connect the shield of the control lines on one side with the reference
ground of the source, e.g. the PLC or CNC.
