Output is high when there is an active start
command (that is via digital input bus
connection, hand-on, or auto-on), and no
stop or start command is active.
[124] Running reverse Output is high when the frequency
converter runs counterclockwise (the logical
product of the status bits running AND
reverse).

Output is high when the frequency
converter is in

[188] AHF Capacitor
Connect
The capacitors are turned on at 20%
(hysteresis of 50% gives an interval of 10–
30%). The capacitors are disconnected below
10%. The off delay is 10 s and restarts if the
nominal power goes above 10% during the
delay.
parameter 5-80 AHF Cap Reconnect
is used to guarantee a minimum off-
time for the capacitors.
[189] External Fan
Control
The internal logics for the internal fan
control is transferred to this output to make
it possible to control an external fan
(relevant for hp duct cooling).

[221] IGBT-cooling
Use this option for handling the overcurrent
trips. When the frequency converter detects
an overcurrent condition, it shows
alarm 13,
Overcurrent
and triggers a reset. If the
overcurrent condition occurs the third time
in a row, the frequency converter shows
alarm 13, Overcurrent
and initiates a 3-
minute delay before the next reset.
