The drive units are placed
near the noise source.
The connection cable
between the QD75 and
drive units is too long.
The QD75 and drive units
are placed closely.
The connection cable
between the QD75 and
drive units is separately
laid from the power line
(in this example, the cable
is outside of the duct) and
is as short as possible.
(11) The influence of noise may be reduced by installing ferrite cores to the cable
connected to the QD75 as a noise reduction technique.
For the noise reduction techniques related to connection with the servo amplifier,
also refer to the instruction manual of the servo amplifier.
