In order to reduce the interference level from the entire system (unit + installation), make motor and brake cables as short as possible. Avoid placing
cables with a sensitive signal level alongside motor and brake cables. Radio interference higher than 50 MHz (airborne) is especially generated by the
control electronics.
3.5.2 EMC Test Results
The following test results were obtained using a system with an adjustable frequency drive (with options, if relevant), a shielded control cable, a
control box with potentiometer, as well as a motor and motor-shielded cable.
