X If you configure a programmable relay output as FA2, you must
also, under PNU C042, enter the frequency from which the FA2
signal is active during acceleration.
X With PNU C0043, set the respective frequency which is to
remain active until the FA2 signal is deactivated during
deceleration.
X Do the same for FA3.
X Program one of the relay outputs K23-K24 or K33-K34 as FA1
to FA3 output by entering one of the following values in the
corresponding PNU (C021 or C022) or in PNU C026 for
signalling relay contacts K11-K12:
–FA1: 01
–FA2: 02
–FA3: 06
By default, FA1 is assigned to relay output K23-K24.

entered here is exceeded during deceleration (a fig. 89
and fig. 90).
