Step 2: Change the method of " Resonance Suppression Filter 3 " to " Adaptive ", and then click to
download
Step 3: After the download is complete, the drive will automatically detect vibration and run
immediately.
10.5.3 Setting the notch lter manually
Analyze resonance frequencies
To manually set the notch lter, it is necessary to measure the actual frequency when resonance
occurs. You can use the " Mechanical Analysis " function in the Luna software.
Analysis types:
Analysis type Applicable load Method Description Precautions
Mechnical Open-loop
Horizontal load
Analyzing the resonance of a servo
system in open loop mode allows users
to analyze the real time resonance
frequency of the entire system. This is
because open loop mode does not use
the PID of the controller which might
otherwise try to react to resonance and
thereby provide a skewed analysis.
For mechanical open-loop analysis,
the drive needs to be disabled, so it
cannot be used for vertical loads
Velocity Closed-loop
Horizontal load
Vertical load
Analyzing the resonance of a servo
system in velocity mode can also
be used. However, it is necessary to
ensure that PID loop parameters are
set reasonably so that the closed loop
nature of the system will not skew
analysis of the resonance frequency.
◆
The control mode of the drive needs to
be in the command speed mode, that is,
the set value of P1-00 is 10.
◆
The drive needs to be enabled when
speed closed-loop analysis is performed
◆
For vertical loads, ensure that there is
mechanical protection against falling.
