Chapter 6 Control Modes of Operation
Settings:
When P1-29 is set to 1, the system will find this detection level automatically. If the
setting value of P1-30 is too low, the detection of frequency will become sensitive
and result in erroneous measurement. If the setting value of P1-30 is too high,
although the probability of erroneous measurement will decrease, the frequency
will become difficult to be found especially when the vibration of mechanical
system is less.
The setting value of P1-30 indicates the range of vibration frequency. When the
vibration can not be detected (out of range), it indicates that the setting value of
P1-30 is too high and we recommend the users can decrease the setting value of
P1-30. The users can also use the Scope function provided in ASDA-A2
configuration software to observe the vibration during positioning operation so as
to set P1-30 appropriately.
Manual Mode

There area two groups of low-frequency vibration suppression parameters. The first
group is P1-25 and P1-26 and the second group is P1-27 and P1-28. Using these two
groups of parameters can improve the vibration condition of two different low
frequencies. P1-25 and P1-26 are used to set the occurred vibration frequency and P1-26
and P1-28 are used to set the frequency response after filter function is used. When the
setting values of P1-26 and P1-28 are higher, the performance of frequency response will
be better. However, if the setting value is over high, it may affect the motor operation.
The default setting of P1-26 and P1-28 are both 0, and it indicates that the low-frequency
vibration suppression function is disabled.
Relevant parameters:
P1 - 25 VSF1
Default: 100.0
Applicable Control Mode: PT/PR
Unit: Hz
Range: 1.0 ~ 100.0
Data Size: 16-bit
Display Format: Decimal
Settings:
This parameter is used to set the first group of the low-frequency of mechanical
system. It can be used to suppress the low-frequency vibration of mechanical
system. If P1-26 is set to 0, this parameter is disabled.
