Connect screen connections for the sensor systems and the motor cables to the Motion
Controller to the earthed mounting plate or the screen connection screw on the Motion
Controller by the shortest available route.
The best screening effect is achieved if the braiding is laid flat for instance on a screen
terminal.
If the installation ensures potential equalisation, the braid can also be attached to an
earthed surface on the motor.
Alternatively equalisation currents can also be suppressed by connected the cable
screen at the motor end via a capacitor (approx. 1
μ
F … 2
μ
F / 50 V).
