P505
Abs. minimum frequency
(Absolute minimum frequency)
S P
0.0 ... 10.0 Hz
{ 2.0 }
Specifies
the frequency value that cannot be undershot by the FI. If the setpoint is less than the
abs. minimum frequency, the FI switches off or switches to 0.0Hz.
At the absolute minimum frequency, braking control (P434) 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 lift equipment without speed feedback, this value should be set to a minimum of
2Hz. From 2Hz, the current control of the FI operates and a connected motor can supply sufficient
torque.
NOTE:
Output frequencies of < 4.5 Hz lead to current limitation (chapter
8.4.3).

P506
Automatic error
acknowledgement
(Automatic error acknowledgement)
S
0 ... 7
{ 0 }
In addition to the manual error acknowledgement, an automatic one can also be selected.
0 = No automatic error acknowledgement.
1 ... 5 = Numberof permissible automatic error acknowledgements within one mains-
After mains off and switch on again, the full amount is again available.
6 = Always: an error message will always be acknowledged automatically if the cause of
the error is no longer present.
7 = Via Deactivate enable: acknowledgement is only possible using the OK / ENTER key
or by mains switch-off. No acknowledgement is implemented by removing the enable!
NOTE: If (P428) is parameterised to "ON", parameter (P506) "Automatic error acknowledgement"
must not be parameterised to setting 6 "Always" as otherwise the device or system is endangered
due to the possibility of continuous restarting in the case of an active error (e.g. short-circuit to
earth / short circuit).
