Current monitoring
The parameters that need to be set for monitoring the current depend on the motor.

After motor startup, current limitation I

is active. Current limitation I
2
determines the
current that is permanently permitted. The Ex-e motor current limitation function is ac-
tivated automatically during startup for SEW‑EURODRIVE motors of category 2.
The characteristic curve for MOVIDRIVE
®
B is defined by operating points A, B, and
C. The parameters of group P560 are preset during startup, see following table. The
values are also specified in the EU type examination certificate.

Maximum motor speed
The maximum motor speed must be limited in the "System limits" window. Observe
the following when you set the parameter
maximum speed :
• Maximum speed ≤ motor limit speed
• Maximum speed ≤ maximum gear unit input speed n
emax
(see gear unit nameplate)
when using a gear unit according to Directive 2014/34/EU.
Automatic adjustment
The parameter automatic adjustment is activated via guided startup. Thus, the fre-
quency inverter sets parameter IxR value with each enable signal. A manual change is
not permitted.
Monitoring func-
tion: A 24 V backup mode prevents that the current-time monitoring is reset in case of a
disconnection from the supply system, see chapter "Overload protection" (→
2 130).
