2.2 DLD paralleling
The braking capacity of applications requiring the use of several DLD, placed in the same
electrical control cabinet, can be increased
(1) (2)
. It is only a question of linking the DC buses from
all the DLD using the B4 connector provided for this purpose. The operation quite simply
comprises of combining the braking capacities of all the appliances.
(1) If cycle simultaneity does not exist between the axes:
There is no synchronization between the braking axes
(2) It is possible to use the axes’ synchronism according to the following cycles:
Braking of one axis whilst another axis is accelerating.
(the braking energy is used to accelerate the other axis).
Connections:
Connector Contact Function
B4 1 DC+
B4 2 DC-
Connections are carried out from DC+ to DC+, DC- to DC-.
Maximum number of parallel axes: 6.
Connecting cover cables section: 1mm² minimum (cable reference: UL 1015 AWG16)
Maximum length of connection: 300mm of connecting cable (connection to be kept as short as
possible).
Every axis must remain connected to the electric mains supply (it is absolutely forbidden to
connect 1 axis to the mains and then use the DC bus link as a power supply for the axes
connected via this connection).
Follow the electrical connection plans on pages 25 and 26, especially with regard to all axis and
line fuses.
The axes linked together by the DC buses must be connected to the same electric mains supply.
A clear 10mm must be spaced between each axis.
Plan of dimensions: see page 19
Electrical connection plans: see pages 25 and 26.
