Parameter
set
Available with option
P505 Absolute minimum frequency P Always visible
0.0 ... 10.0 Hz
[ 2.0 ] States the frequency value that cannot be undershot by the FI. If the setpoint becomes smaller than
the absolute minimum frequency, the FI switches off or changes to 0.0Hz.
At the absolute minimum frequency, braking control (P434 or P441) and the setpoint delay (P107)
are actuated. If a setting value of "Zero" is selected, the brake relay does not switch during
reversing.
When controlling lifting equipment, this value should be set at a minimum of 2Hz. From 2Hz and
higher, the current control of the FI operates and a connected motor can supply sufficient torque.

[ 0 ] In addition to the manual error acknowledgement, an automatic one can also be selected.
0 = No automatic error acknowledgement.

6 = Always, an error message will always be acknowledged automatically if the cause of the
error is no longer present.
7 = ENTER key, acknowledgement is only possible using the ENTER key or by mains switch-
off. No acknowledgement is implemented by removing the enable!
