When the differential driver output system (QD75D N/QD75D ) is used, a potential
difference between commons may occur between the differential driver common
terminal and the differential receiver common terminal of the drive unit. To remove the
potential difference between commons, connect the differential driver common terminal
of the QD75D N/QD75D
unit.
When the common terminal of the drive unit is photocoupler-connected, the wiring to
the differential driver common terminal of the QD75D N/QD75D
since a potential difference between commons does not exist.
(For the drive unit specifications, refer to the manual of the used drive unit.)
To wire the differential driver common terminal, use the wire applied to the following
table.
