Setting up the External Amplifier Fault Input
The amplifier fault signal is a bidirectional single-ended input. Its’ minus end is tied internally to the
brake/relay common (pin #8) which dictates how the amplifier fault input should be connected.
brake/relay common (pin #8) which dictates how the amplifier fault input should be connected.
Note
If the amplifier fault signal is not used, it can be treated and used as a
general purpose +12~24V input by setting bit 20 of Ixx24 to 1.
general purpose +12~24V input by setting bit 20 of Ixx24 to 1.
Note
The amplifier fault signal polarity can be changed in software with bit
23 of Ixx24; =1 for High True, =0 for Low True.
23 of Ixx24; =1 for High True, =0 for Low True.
If the brake/relay option is in use (otherwise, whichever scheme desirable):
If pin#8 is wired to common ground, then use the sourcing scheme
If pin#8 is wired to 24V, then use the sinking scheme

External Amplifier Fault Input, Suggested M-Variables:
// External Amplifier Fault Inputs:
M523->X:$078100,15,1 ; Amp. Fault Input (CH5), Connector X9
M623->X:$078108,15,1 ; Amp. Fault Input (CH6), Connector X10
M723->X:$078110,15,1 ; Amp. Fault Input (Ch7), Connector X11
M823->X:$078118,15,1 ; Amp. Fault Input (Ch8), Connector X12
M523->X:$078100,15,1 ; Amp. Fault Input (CH5), Connector X9

M823->X:$078118,15,1 ; Amp. Fault Input (Ch8), Connector X12
This feature is commonly used when an amplifier is commanded through the DAC outputs on X9-X12,
and the need of a fault input signal is required to run the operation safely (i.e. kill in the occurrence of an
amplifier fault).
