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

2.5.2 UP 110 Braking Resistor Module

April 2007
In the energy-recovery inverter, the braking energy of
the motors is normally returned to the line power. If
in an exceptional case the line power is interrupted,
the braking energy cannot be returned. This can lead
to an excessive dc-link voltage that might switch off
the inverter and let the motors coast without control.
To prevent damage to the machine and workpiece
resulting from uncontrolled machine movement, the
energy should be dissipated with the UP 110 braking
resistor module.
In specific cases, a brake integrated in the motor can
be sufficient, or coasting to a stop can be considered
noncritical (e. g. spindle coasting to a stop while the
protective doors are closed). However, it must be
considered for each individual application whether
this is sufficient.
