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.

Warning 165, ATEX ETR freq.lim.warning is active, the output is 1.
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.
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 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.

This option is only available with software version 48.XX.
Homing is completed with the selected homing function in parameter 17-80 Homing Function.
