Required settings on the connected inverters

To protect the MCR91A.. regenerative power supply, the error message must be evaluated.

There are 3 options for evaluating the error message:

• Immediate disconnection of the regenerative power supply from the supply system
• The error message is transmitted directly to the controller. No additional settings are required on the device itself.
• Immediate switch-off of the connected inverters
• The error message is applied to a digital input of all the connected inverters. Parameterize this digital input to "External fault – active". Set the fault response to "Output stage inhibit".
• Stopping the connected inverters in a controlled manner
• The error message is applied to a digital input of all the connected inverters. Parameterize this digital input to "External fault – active". Set the error response to either "Emergency stop + output stage inhibit" or "Application stop + output stage inhibit".
