13.9.3 Overcurrent monitoring
This funcon monitors the instantaneous value of the motor current and serves as motor pro-
tecon.
WARNING!
With an incorrect
parameterisaon, the maximum permissible motor current may be excee-
ded in the process.
Possible consequences: irreversible damage of the motor.
Avoid motor damages by using the overcurrent monitoring funcon as follows:
▶
The seng of the threshold for the overcurrent monitoring in 0x2D46:001 must be adapted
to the connected motor.
▶
Set the maximum output current of the inverter in 0x6073 much lower than the threshold
for overcurrent monitoring.
Condions for using this funcon
This funcon is suitable for a synchronous motor.

•
If the acve motor current exceeds the set threshold, the response
set in 0x2D46:002 is eected for the purpose of motor protecon.
•
The par
ameter can also be set and overwrien by selecng a motor
fr
om the "motor catalog" of the engineering tool.
0x2D46:002 Overcurrent monitoring: Response Selecon of the response to the triggering of motor current monitoring.

13.9.4 Motor phase failure detecon
The motor phase failure detecon funcon can be acvated for both synchronous and asyn-
chr
onous motors.
In the Lenze
seng, monitoring is not acvated!
Precondions
Motor phase failure detecon during operaon is suitable for applicaons which are operated
with a c
onstant load and speed. In other cases, transient processes or unfavourable operang
points can cause erroneous triggering to occur.
