Evaluation of the DC link ready signal and error message

The "DC link ready" terminals and the error message from the MCR91A.. regenerative power supply must be connected.

Proceed as follows:

  1. Connect the "DC link ready" output X60:1 of the regenerative power supply unit to an input from the inverter parameterized to "DC link ready".
    • If the "DC link operation" message is not passed on to the inverters, output stage enable is not possible.
  2. Connect the "Error" output X60:4 of the regenerative power supply unit to an input from the inverter parameterized to "Error".
  3. Parameterize the response to "external fault" as required.
