3.27 MB 620 machine operating panel
For machines with up to six axes, HEIDENHAIN offers the MB 620 machine
operating panel (15-inch) with HSCI interface.
On the underside of the machine operating panel are terminal strips bearing
the PLC inputs as well as the PLC outputs. Also, connection X23 (347) for HR
handwheels is on the underside of the MB 620.
It must be ensured that negative pressure cannot develop in the panel in
which the machine operating panel is installed. Negative pressure in the panel
can lead to increased contamination of the machine operating panel, which
must be avoided by enabling pressure compensation, for example via the
cable duct between the electrical cabinet and the panel.
Besides the snap-on keys, there are also keys with switch contacts that can
be wired by the machine tool builder depending on the application.
Specifications of the switch contacts on keys such as EMERGENCY STOP,
NC start, NC stop, Control voltage on:
Rated voltage: +24 V DC
Maximum current: 1.2 A
