Uv(R) 1X0(D) Power Supply Unit - HEIDENHAIN TNC 410 M Technical Manual

2.4.3 UV(R) 1x0(D) Power Supply Unit

2 – 38
The regenerative UV(R) 1x0(D) power supply
units supply the dc-link voltage as well as the
power for the electronics of the control and
power modules.
During braking, the motors feed energy into
the dc-link. The UVR 1x0 D returns this
energy to the power line.
The UVR 1x0(D) can be driven only with
commutating reactor and line filter.
