Lenze i550 - Motor Speed Monitoring

10.8.5 Motor speed monitoring
This funcon monitors the motor speed during operaon.
Precondions
•
In order to detect the current motor speed, the inverter must be enabled and the motor
must rotate.
•
For an exact monitoring, rated motor speed 0x2C01:004 (P320.04) and rated motor fre-
quency 0x2C01:005 (P320.05) must be set correctly.
Details
•
If the motor speed reaches the threshold set in 0x2D44:001 (P350.01), the response set in
0x2D44:002 (P350.02) takes place.
•
With the seng 0x2D44:002 (P350.02) = "No response [0]", the monitoring funcon is
deacvated.

Warning/error threshold for motor speed monitoring.
•
If the motor speed reaches the threshold set, the response selected in
0x2D44:002 (P350.02) is eected.
•
The parameter can be set and thus overwrien by selecng a motor
in the engineering tool from the "motor catalogue".
