Reference Pulse Inhibit Input - HEIDENHAIN TNC 415 Technical Manual

7 Reference pulse inhibit input

The reference pulse inhibit input can be used to suppress the evaluation of the reference pulse input
of each of the six measuring systems. This is achieved by simply applying a positive potential (13 V
to +30.3 V) to the appropriate reference pulse inhibit input. Pin 9 of the female connector X10
(reference pulse inhibit) must be connected to 0 V of the PLC-power supply.
The reference pulse inhibit inputs are only available in the LE 415 A. These inputs are
normally unused. See also Chapter "Machine Integration".
