Set points for the AMF sequence
The timers must have some set points to indicate when they are to start. The AGC has different set points for the different situations.
The limits that the mains voltage must be within before the failure timer starts, are set in parameters 7063 and 7064. There is a low
(7063) and a high (7064) limit. Furthermore, the AGC has limits for the frequency. This also has a low limit (7073) and a high limit
(7074). If the mains voltage or frequency has exceeded one of these limits and the relevant fail timer has expired, the AMF
sequence will be started.
