ASDA-M Chapter 6 Control Mode of Operation
Revision December, 2014 6-21
Settings：
When enabling the auto suppression (P1-29 = 1), it will
automatically search the detection level. The lower the value is,
the more sensitive of the detection will be. However, it is easy to
misjudge the noise or regard the other low-frequency vibration as
the suppression frequency. If the value is bigger, the system will
make more precise judgment. However, if the vibration of the
mechanism is smaller, it might not detect the frequency of
low-frequency vibration.
P1-30 is to set the range to detect the magnitude of low-frequency vibration. When the
frequency is not being detected, it is probably because the value of P1-30 is set too big
which exceeds the range of vibration. It is suggested to decrease the value of P1-30.
Please note that if the value is too small, the system might regard the noise as the
vibration frequency. If the SCOPE is available, it can be used to observe the range of
position error (pulse) between upper and lower magnitude of the curve and set up the
appropriate value of P1-30.
Manual Setting:
There are two sets of low-frequency vibration suppression. One is parameter
P1-25~P1-26 and another one is parameter P1-27~P1-28. These two sets of
low-frequency vibration suppression can be used to eliminate two different frequency
vibration. Parameter P1-25 and P1-27 are used to suppress the low-frequency vibration.
The function is working only when the parameter setting value of low-frequency vibration
close to the real vibration frequency. Parameter P1-26 and P1-28 are used to set the
response after filter. The bigger the setting value of P1-26 and P1-28 is, the better
response will be. However, if the value is set too big, the motor might not operate
smoothly. The default value of parameter P1-26 and P1-28 is 0, which means the
function is disabled. Followings are the related parameters:
