Connecting The Up 110 Braking Resistor Module - HEIDENHAIN TNC 410 M Technical Manual

6.6 Connecting the UP 110 Braking Resistor Module

X79: Unit bus
6 – 66
The UP 110 braking resistor module must be used when axis motors without
brakes are used. In the event of power failure, it dissipates the energy
returned by the axis motors to the dc link. The UP 110 is switched on when
the inverter voltage U
falls below 720 V.
Danger
Danger of electrical shock!
The UP 110 braking resistor module may be opened only by HEIDENHAIN
service engineers.
Do not engage or disengage any terminals while they are under power.
