Advanced ETR
If [20] ATEX ETR is selected, follow the instructions in the dedicated chapter of the design guide and the instructions provided by
the motor manufacturer.
If [20] ATEX ETR is selected, set parameter 4-18 Current Limit to 150%.

No
No external fan is required, that is the motor is derated at low speed.
[1]
Yes
Applies an external motor fan (external ventilation), so no derating of the motor is required at low speed. The

rent (see parameter 1-24 Motor Current). If the motor current exceeds nominal current, the operation time still
decreases as if no fan was installed.

Description
Calculates the load when set-up 1 is active and stops (trips) the drive when the motor is overloa-
ded. Program a warning signal via 1 of the digital outputs. The signal appears in the event of a
warning and if the drive trips (thermal warning).
Activates the thermal monitoring function for Ex-e motors for ATEX. Enables parameter 1-94 ATEX
ETR cur.lim. speed reduction, parameter 1-98 ATEX ETR interpol. points freq., and parameter 1-99
ATEX ETR interpol points current.
