Connection
When connecting the output reactor, you must take into account the following conditions to
ensure that it functions correctly:
● With analog control cables, connecting the shield at both ends can result in coupled-in
noise. To prevent this, the shield must only be connected at one end on the Power
Module.
● Control cables must be routed separately from power cables. Power cables are motor
cables or connecting cables from the DC link of the Power Module (terminals DCP/DCN)
to other components (e.g., Braking Module). In particular, you must ensure that control
cables and power cables are not routed in parallel in a joint cable raceway, even if all the
cables are shielded.
● You must use shielded motor cables. The shield for the motor cable must be attached to
the shield plate in the cabinet and motor housing.
● The ground wire for the motor must be fed directly back to the Power Module.
