center frequency is set to 400Hz and the bandwidth to 200 the signal will be reduced by 3dB
starting at 300hz. It will have the greatest reduction at 400Hz, and then will be greater than 3dB
above 500Hz. When setting the notch filter a chart is displayed that provides an indication of the
filtering that will be accomplished.
5.4 Getting Ready for Tuning
Before testing a servo-system a few more parameters need to be entered. These include the Max
Speed, Acceleration and Distance (or time) requirements of the sample move. The proper profile
shape of the move is needed to operate the load in the same way as what will be expected during
online operation. Accelerating the load quickly may induce significant ring into the motion profile.
Accelerating slower and going to a higher velocity can minimize the ringing. The best profile
for a given move is sometimes arrived at more through experimentation than hard calculation.
SSM QuickTuner provides easy entry of the profile parameters plus a display of the profile for
verification.
The mechanical system should be set up as close to the final configuration as possible so that the
tuning represents what will be expected. The critical components include the coupler, mechanical
interface ,and similar frictional and inertial loads. As tuning can sometimes be an uncontrolled
process where the mechanical system can be damaged, care must be taken to minimize this
possibility. This could include having limit sensors or mechanical stops that help to prevent such
damage.
SSM Quick Tuner contains a sampling Oscilloscope that will display of variety of measurements of
an executed move. Two plots can be displayed at one time and contain the real-time information
about the move performance. Before performing the test move, make sure the desired move
information is selected. This can include the typical information such as
Actual Speed
or
Position
Error
but also can include the
Supply Voltage
so that the power supply can be monitored for
