The UE 1xx, UE 2xxB or UR 2xx compact inverters supply power to the control
via the 50-line ribbon cable (exception: See "Additional power supply" on
page 5 – 34.).
The control transmits the PWM signals for the axes and spindle(s) to the
UE 1xx, UE 2xxB or UR 2xx compact inverters via 20-line ribbon cables.
U dc-link power is supplied to the additional UM 111(D) power module from
Z
the UE 2xxB or UR 2xx(D) compact inverter via a conductor bar, which is
screwed to the power module and the compact inverter. A second power
conductor establishes the ground connection between the UE 2xxB or
UR 2xx(D) and the UM 111(D).
The power bars are supplied as accessories with the power modules.
A 40-line ribbon cable connects the UE 2xxB or UR 2xx(D) with the UM 111(D)
power module, forming the unit bus.
Direct drives (linear motors, torque motors) used in conjunction with
regenerative inverter systems require a ZKF 1xx dc-link filter, which is
mounted to the left of the direct drives' power modules. The dc-link current is
then led through this filter.
With the UE 2xx B and UR 2xx(D), the ribbon cables must be covered to
protect them against interference.
The covers for the control and the UE compact inverter are included with each
as accessories.
The cover for an optional UM 111(D) power module must be ordered
separately.
If several encoders with a high current consumption (e.g. encoders with EnDat
interface) or the dual-processor MC 422B are connected in conjunction with a
compact inverter or a power supply unit, however, an additional power supply
source might become necessary. The additional UV 105 power supply unit can
be used for this purpose. It is mounted next to the control at its left.
The power supply unit is connected to the dc-link voltage via the conductor bar
of the previous left module. The upper conductor bar also establishes the
ground connection of the dc-link.
The 50-line ribbon cable of the compact inverter / power supply unit for
transmitting the status signals is connected to X69 of the UV 105. The free
ribbon cable of the UV 105 is connected to X69 of the control.
The 5-V power supply (X74) of the UV 105 is connected to the terminals on the
control (X74) by using the litz wires included with the UV 105.
