Output is high when
parameter 3-13 Reference Site = [1] Remote or
[0] Linked to hand/auto while the LCP is in
auto-on mode. See Table 3.22
Output is high when no alarm is present.
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.
converter runs counterclockwise (the logical
product of the status bits running AND
reverse).
Output is high when the frequency
converter is in hand-on mode (as indicated
by the LED light above [Hand On]).
Output is high when the frequency
converter is in auto-on mode (as indicated
by the LED light above [Auto On]).

Advanced ETR. If Alarm 164 ATEX ETR
cur.lim.alarm is active, the output is 1.
Selectable if parameter 1-90 Motor Thermal

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
Delay is used to guarantee a minimum off-
time for the capacitors.
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).

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 3
a row, the frequency converter shows alarm
13, Overcurrent and initiates a 3-minute delay
before the next reset.

This option is available only with
software version 48.XX.
Homing is completed with the selected

NOTICE
This option is available only with

Positioning is completed and the on-target
signal is sent when the actual position is
within parameter 3-05 On Reference Window
for the duration of parameter 3-09 On Target
Time and the actual speed does not exceed
parameter 3-05 On Reference Window.
