General information

6.1.1

Line routing

Observe the valid provisions for your machine or system, e.g. DIN IEC 60364 or DIN EN
50110, during the installation of electrical equipment.
6.1.2

Grounding, shielding and EMC

Observe the following factors for grounding, shielding and EMC.
For synchronous servo motors, the connection to PE is made using the cable for the

power supply (see
have an externally attached and marked grounding connection.
Use a ring core or a motor throttle near the servo amplifier for the power supply cable
}
as needed. Observe the specifications in the operating manual of the servo amplifier
used.
You need shielded cables for power cables.
}
You need shielded cables for data and control cables.
}
Apply (low-impedance) shielding extensively over metallized connector housings or
}
EMC-compatible cable glands.
Use a suitable connection material to apply the cable shield to the ground rail or shield

Connection method [
Apply inner and outer shielding on both sides (e.g. at a shield wire bus bar).
Apply the outer shielding on both sides (e.g. at a shield wire bus bar).
Apply the inner shielding on the side of the servo amplifier (e.g. at a shield wire bus
bar).
If equalizing current is expected when using longer cables, it can be prevented with
voltage-equalizing cables.
