6.1.2 Earthing, shielding and EMC
Note the following points:
•
On the servo motors, the connection to PE is established via the supply voltage cable
(see section 6.2 Servo motor and motor brake). For an additional earth in accordance
with DIN EN 60204-1, the motors have an earth connection attached and indicated
on the exterior.
• If necessary, use a toroidal core for the supply voltage cable, or a motor throttle close
to the servo amplifier. Please refer to the information stated in the operating manual
of the servo amplifier you are using.
• You will need shielded cable for data and control lines.
–
Earth the inner and outer cable shield connections on both sides (e.g. on a bus
bar).
• You will need shielded cable for data and control lines.
–
Earth the outer cable shield connection on both sides (e.g. on a bus bar).
– Earth the inner cable shield on the side of the servo amplifier (e.g. on a bus bar).
– If you are using longer cables and there is the possibility of transient currents,
these can be prevented by using equipotential bonding cables.
• Shields should be connected over a wide surface area (low impedance), using metal-
lised connector housings or EMC-compliant cable screw connections.
• An appropriate connection material should be used to connect the cable shield to the
earth bar or bus bar (e.g. shielded terminals, see Fig. 6-1: ).
