Twisted Wires
Twist unshielded wires belonging to the same circuit (feeder and return cable)
or keep the surface between feeder and return cable as small as possible. Wires
that are not used have to be grounded at both ends.
Lines of Measuring Systems
Lines of measuring systems must be shielded. Connect the shield to ground at
both ends and over the largest possible surface area. The shield may not be in-
terrupted, e.g. using intermediate terminals.
Digital Signal Lines
Ground the shields of digital signal lines at both ends (transmitter and receiver)
over the largest possible surface area and with low impedance. This avoids low
frequency interference current (in the mains frequency range) on the shield.
Analog Signal Lines
Ground the shields of analog signal lines at one end (transmitter or receiver)
over the largest possible surface area and with lower impedance. This avoids
low frequency interference current (in the mains frequency range) on the shield.
Connection of Mains Choke
Keep connection lines of the mains choke at the drive controller as short as pos-
sible and twist them.
Installation of Motor Power Cable
● Use shielded motor power cable or run motor power cables in a shielded duct
● Use the shortest possible motor power cable
● Ground shield of motor power cable at both ends over the largest possible
surface area to establish a good electric connection
● It is recommended to run motor lines in shielded form inside the control cabi-
net
● Do not use any steel-shielded lines
● The shield of the motor power cable must not be interrupted by mounted
components, such as output chokes, sine filter or motor filters
