The power modules are arranged between the power supply unit and the
control. The power module for the spindle is placed next to the power supply
unit, and the power modules for the axes are then placed in order of
decreasing rated current.
If the UP 110 braking resistor module is used together with the regenerative
power supply units, the braking resistor is arranged between the weakest
power module and the control.
The power module for a second spindle (not on all controls possible) is placed
between the power module for the first spindle and the strongest power
module for the axes.

4–30.

unit via conductor bars (screwed onto each module, and if required, the
UP 110).
A further conductor bar establishes the ground connection between the
individual modules.
Three conductor bars are included as accessories with the power modules
(two for the dc-link, one for the ground).
A 50-line ribbon cable connects the control with the UV(R) 1x0 and supplies
the power to the control.
A 40-line ribbon cable connects the power supply unit with the power
modules, and if required with the UP 110, forming the unit bus.
The 20-line ribbon cables connect the control and the power modules, and
supply the PWM signals to the axes and the spindle(s).
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.
