Note 1 : Actuation driven with MTAD4002 (without external load)

Setup

 

Result

 

Conclusion

・Short rise time(0.5ms) and short falling time(0.4ms).
・Minimum residual vibration at the location of 300μm.

 

 

Note 2 : Actuation driven with MTAD4002 (with external load 52g)

Setup

 

Result

 

Conclusion

・Even with an external load of 52g, the rise time increase from 0.5ms to 1.14ms while the
falling time increase from 0.4ms to 1.11ms.
・Minimum residual vibration at the location of 300μm.

 

 

Note 3 : Comparison of Actuation driven (without load and external load 52g)

Setup

 

Result

 

Conclusion

・The MTKK10S300F120PS can handle an external load to the distance of 300μm firmly
and stably.

 

 

Note 4: Natural Resonant Frequency vs External Mass

The figure shows the relationship between the natural resonant frequency against the external mass. When there is no external mass added on MTKK10S300F120PS, the natural resonant frequency is measured as 1221Hz. However, when there is an external mass loaded on the MTKK10S300F120PS, the natural resonant frequency become lower as shown as figure below.
Therefore, it is important to know the natural resonant frequency of your system when applying the MTKK10S300F120PS.
