    chain leadshine fault outputs?

    Hi there!

    Quick question: can I chain the fault output of mutlitple CS-D508 drivers like this?

    Please somebody! Maybe my schematic isn't clear enough?

    The manual does not explicitly say whether the alarm logic is positive or negative. If it is what I think it is, you can connect all ALM+ and ALM- outputs in parallel. An alarm in any driver(s) will pull the FAULT signal low.

    I can't see why not.
    Your attachment file doesn't work so I can't see how you wired it. So........

    If the ALM circuit is normally closed NC when drive is active and opens the circuit NO when a fault happens, then you would wire them in series.
    If the ALM circuit is normally open NO when drive is active and closes the circuit NC when a fault happens, then you would wire them in parallel.
    It says the ALM is configurable to a certain extent so this could possibly be adjustable.
    Manual suggests the alarm circuit sinks to ground.

    This circuit can then go to one of your controllers optocoupler inputs to trigger a stop.
    Or if your controller has lots of inputs, then you could just do them individually and assign each one.
    Or even use a multi channel optocoupler module between the two.

    Depending on your controller software you could assign one of the buttons such as stop or feed hold etc.
