Check list
Anyone connecting a machine with a HEIDENHAIN inverter system must
take note of the information presented there. The revised version of Chapter
4 is available for downloading from the FileBase.
New axis-release module
An axis-release module is used to switch a group of axes on and off
independently of other axes. The new axis-release module makes it possible
to address both axes and spindles as "axis groups." The selection is made
using jumpers.
ID number of the new axis-release-module: ID 573 732-02
It replaces the previous axis-release module (ID 341 518-02). The new axis-
release module is compatible in its functions to its predecessor, but the
installation differs. Comprehensive mounting instructions are included with
the new axis-release module.
VAL-MS surge voltage arrester
The VAL-MS 230/FM single-pole surge voltage protector from Phoenix
serves to protect the machine from overvoltages on the conductors, and
separates the protection element from the mains when it has become
overloaded due to high-energy surge voltages. Three surge arresters are
necessary for a machine tool connected to three-phase line power. The
surge arrester is also equipped with a double-throw switch as a remote
indicator switch.
