13.9.3 Overcurrent monitoring
This function monitors the instantaneous value of the motor current and serves as motor pro-
tection.
WARNING!
With an incorrect parameterisation, 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 function as follows:
▶
The setting 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.
Conditions for using this function
This function is suitable for a synchronous motor.
Parameter
Address Name / setting range / [default setting] Info
0x2D46:001 Overcurrent monitoring: Threshold
0.0 ... [5.4] ... 3000.0 A
•
If the active motor current exceeds the set threshold, the response
set in
0x2D46:002 is effected for the purpose of motor protection.
•
The parameter can also be set and overwritten by selecting a motor
from the "motor catalog" of the engineering tool.
0x2D46:002 Overcurrent monitoring: Response Selection of the response to the triggering of motor current monitoring.
Associated error code:
•
9092 | 0x2384 - RANLI_CIMES_0500_03891
0 No response

13.9.4 Motor phase failure detection
The motor phase failure detection function can be activated for both synchronous and asyn-
chronous motors.
In the Lenze setting, monitoring is not activated!
Preconditions
Motor phase failure detection during operation is suitable for applications which are operated
with a constant load and speed. In other cases, transient processes or unfavourable operating
points can cause erroneous triggering to occur.
Parameter
Address Name / setting range / [default setting] Info
0x2D45:001 Motor phase failure detection: Response - Motor
phase 1 Selection of the response following the detection of a motor phase fail-
ure during operation.
Associated error codes:
•
65289 | 0xFF09 - Motor phase missing
•
65290 | 0xFF0A - Motor phase failure phase U
•
65291 | 0xFF0B - Motor phase failure phase V
•
65292 | 0xFF0C - RANLI_CIMES_1000_20883
