Acknowledge a Fault

If a fault is present the 'Cntrl' menu is replaced with the menu to acknowledge faults (top level menu, left hot key). While a fault is
present it is not possible to enter the Motor Control menu until the fault has been acknowledged. When entering the error menu the
latest fault message is displayed. By pressing the right hot key 'Reset' you acknowledge the fault. If there is another fault pending it is
displayed and can also be acknowledged until there is no further fault pending. Using the up/down keys it is possible to scroll
through the list of present faults before acknowledging them. If the last fault was acknowledged the main menu is automatically
entered. The menu can be exited at any time pressing the left hot key 'Back' without resetting any faults.

The table in the section "Error Handling, Maintenance and Service->Error Handling of the UMC" lists all diagnosis
and fault messages and potential root causes for the fault. It gives you a first indication of where to look for a fault
and how to fix it. Use the error number shown in the heading (Error 83 in the example) for the look-up table.
