[121] Remote Output is high when
reference parameter 3-13 Reference Site = [1] Remote
active or [0] Linked to hand/auto while the LCP is
in Auto On mode. See Table 3.20.
[122] No alarm Output is high when no alarm is present.
[123] Start command Output is high when there is an active
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 Output is high when the frequency
reverse converter runs counterclockwise (the
logical product of the status bits running
AND reverse).
[125] Drive in hand Output is high when the frequency
mode converter is in Hand On mode (as
indicated by the LED light above [Hand
on]).
[126] Drive in Auto Output is high when the frequency
mode converter is in Auto On mode (as
indicated by the LED light above [Auto
On]).
[151] ATEX ETR cur. Selectable if parameter 1-90 Motor
alarm Thermal Protection is set to [20] ATEX ETR
or [21] Advanced ETR. If Alarm 164 ATEX
ETR cur.lim.alarm is active, the output is 1.
[152] ATEX ETR freq. Selectable if parameter 1-90 Motor
alarm Thermal Protection is set to [20] ATEX ETR
or [21] Advanced ETR. If Alarm 166 ATEX
ETR freq.lim.alarm is active, the output is
1.
[153] ATEX ETR cur. Selectable if parameter 1-90 Motor
warning Thermal Protection is set to [20] ATEX ETR
or [21] Advanced ETR. If Alarm 163 ATEX
ETR cur.lim.warning is active, the output is
1.
[154] ATEX ETR freq. Selectable if parameter 1-90 Motor
warning Thermal Protection is set to [20] ATEX ETR
or [21] Advanced ETR. If Warning 165 ATEX
ETR freq.lim.warning is active, the output
is 1.
[188] AHF Capacitor The capacitors are turned on at 20%
Connect (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 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 third time in a row,
the frequency converter shows alarm 13,
Overcurrent and initiates a 3 minute delay
before the next reset.
Homing is completed with the selected
homing function (parameter 17-80 Homing
Function).
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.
The position error exceeds the value in
parameter 4-71 Maximum Position Error for
the time set in parameter 4-72 Position
Error Timeout.
The position is outside the limits set in
parameter 3-06 Minimum Position and
parameter 3-07 Maximum Position.
Target position is reached in touch probe
Target position mode.
Touch probe positioning active. The
Activated frequency converter monitors the touch
probe sensor input.
