Ur 2Xx(D) Compact Inverter - HEIDENHAIN TNC 410 M Technical Manual

2.3.5 UR 2xx(D) Compact Inverter

2 – 20
With the regenerative
UR 2xx(D) compact inverters,
the power electronics for all of
the axes and the spindle, as well
as the power supply for the
control are all contained in a
single unit. An additional
UM 111(D) power module of
the modular inverter system can
be connected via conductor bar.
The PWM signals are
transferred via external 20-line
ribbon cables.
Warning
Direct drives (linear motors, torque motors) must not be connected directly
to regenerative UR 2xx(D) compact inverters → Danger of destruction!
Direct drives may be used only in conjunction with an additional power
module, e.g. the UM 111D, which is connected to the dc-link of the
UR 2xx(D) via a ZKF 1xx.
