6.2.9 Connecting to a converter
Selecting and connecting the cable
To connect the motor to a converter, use MOTION-CONNECT cables or shielded connection
cables. The protective braided shield, made up of as many strands as possible, must have a
high electrical conductivity. Braided shields made of copper or aluminum are well suited to
this purpose.
The shield must be connected at both ends to the motor and the converter; unshielded cable
ends must be kept as short as possible.
To ensure good discharging of high-frequency currents, provide contacting over a large
surface area: as 360° contacting at the converter.
