Parameter enables the possible
limitation on maximum output fre-
quency when connected to AC
mains (digital input from P3.5.1.53
is active), in case the available
voltage is not sufficient to reach
the motor nominal U/f ratio (from
P3.1.1.1 and P3.1.1.2).
The function can be useful if the
motor has been chosen depending
on high DC voltage from solar
modules, but this voltage is not
reachable with AC supply.
