ASDA-A3
P2.057▲
Default: 0
Unit: Hz
Format: DEC
Settings:
If you are unsure about setting P2.054 - P2.056, set the value of synchronous control bandwidth instead
so that the value corresponds to P2.054 - P2.056.
1. When the synchronous control bandwidth is greater than the servo bandwidth, the synchronous
following is better.
2. When the servo bandwidth is greater than the synchronous control bandwidth, the single-axis motion
following is better.
When the servo bandwidth plus the synchronous control bandwidth (P2.057) is greater than the
system's allowable bandwidth, however, it causes system resonance.
Note: when increasing the bandwidth for both speed loop and synchronous control, ensure the response of P2.025 is
much faster than the setting of both bandwidths. Therefore, decrease P2.025 as needed.
P2.058
Default: 0
Unit: 0.1 ms
Format: DEC
Example: 15 = 1.5 ms
Settings:
When the synchronous control is affected by low resolution, meaning that noise (less sharp and rough
sound) is generated, use low-pass filter suppression. This filter must be faster than the synchronous
control bandwidth.
