Illustration 3.28 Example of the output function
t represents the off delay timer (10 s).
1
t represents the Capacitor Reconnect Delay (5-80 AHF Cap
2
Reconnect Delay).
When the nominal power of the frequency converter
exceeds 20%, the output function turns on. When the
power goes below 10% there is an Off Delay Timer that
needs to expire before the output goes low, this is
represented by t . After the output goes low, the capacitor
1
reconnect delay timer needs to expire before the output is
allowed to be on again, represented by t
the nominal power is above 30% and the relay does not
turn on.
3.7.7 5-9* Bus Controlled
This parameter group selects digital and relay outputs via
a fieldbus setting.
5-90 Digital & Relay Bus Control
Range: Function:
0 [0 - This parameter holds the state of the
*
2147483647 ] digital outputs and relays that is controlled
by bus.
A logical '1' indicates that the output is
high or active.
A logical '0' indicates that the output is low
or inactive.
