Frequency value messages FA1/FA2
The digital output configured as FA1 will be activated as soon as
the setpoint frequency is achieved.
The digital output configured as FA2 is activated as long as the
frequencies set under PNU C42 and C43 are exceeded.
To ensure a certain level of hysterysis, the FA1 and FA2 signals are
activated 0.5 Hz before the frequency setpoint value or the
frequency value set under PNU C42 is achieved and deactivated
1.5 Hz after the frequency setpoint value or the frequency value
set under PNU C43 is achieved.
X If you want to configure a programmable output as FA2, you
must set the frequency under PNU C42, at which the FA2 signal
is to be generated in the acceleration phase.
X With PNU C43, you set the respective frequency which is to
remain active until the FA2 signal is deactivated during decele-
ration.
X Program one of the digital outputs 11 or 12 as an FA1 or FA2
output by setting under PNU C21 or C22, the value 01 for FA1
or 02 for FA2.
