12 Machine operating panel
A separate 37-pin female connector (X46) is mounted on the logic unit for the connection to the
machine operating panel. This connector includes the PLC inputs I128 to I152, the PLC outputs
O0 to O7, as well as the 0 V and +24 V of the PLC power supply. The PLC inputs I128 to I152 may
be connected only with the power supply from pins 36 and 37, since this power supply is internally
secured as required.
HEIDENHAIN now offers a machine operating panel. It is installed beneath the TNC keyboard. The
dimension drawings show the standard set of keys. Four additional black keys are supplied with the
panel. The machine tool builder to use them replace unneeded axis keys, for example. Keys with
other symbols are also available upon request.
