[152] ATEX ETR freq. alarm Selectable if
parameter 1-90 Motor 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.

Selectable if
parameter 1-90 Motor 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.

[180] Clock fault
[181] Prev. maintenance
[188] AHF capacitor con-
nect
The capacitors are turned on at 20% (hysteresis of 50% gives an interval of 10– 30%). The capaci-
tors 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 mini-
mum 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 drive detects an overcurrent condi-
tion, it shows
alarm 13, Overcurrent
and triggers a reset. If the overcurrent condition occurs for the
3
rd
time in a row, the drive shows
alarm 13, Overcurrent
and initiates a 3-minute delay before the
next reset.
[222] Homing OK
N O T I C E
This option is only available with software version 48.XX.
Homing is completed with the selected homing function in
parameter 17-80 Homing Function
