Lenze I51AE175F - Motor Speed Monitoring; Motor Torque Monitoring

8.7.5 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 is calculated and set in the course of the automac
idencaon of the motor.
•
The parameter can also be set and thus overwrien by selecng a
motor in the engineering tool from the "motor catalog" or calibrang
the motor.

8.7.6 Motor torque monitoring
This funcon monitors the motor torque during operaon.
Precondions
The motor torque monitoring can only be used for the following motor control types with
speed controller:
•
Sensorless control (SL PSM)
•
Sensorless vector control (SLVC)
Details
This funcon sets the internal status signal "Torque limit reached [79]" = TRUE if the maximum
possible torque has been reached.
•
The status signal is set irrespecve of the response 0x2D67:001 (P329.01) and delay me
0x2D67:002 (P329.02) set for this monitoring.
•
The user can use the status signal to acvate certain funcons. 4Flexible I/O congura-

The status signal also serves to set a digital output or a bit of the NetWordOUT1 status
word. 4
