AI1 signal filtering time (04-01)
(3)
AI2 signal filtering time (04-06)
All analog inputs (AI1, AI2) have a 1st order programmable input filter that can be adjusted when noise is present on
each of the incoming analog signal to prevent erratic drive control.
The filter time constant (range: 0.00 to 2.00 seconds) is defined as the time that the input step signal reaches 63% of
its final value.
Note:
Increasing the filter time causes the drive operation to become more stable but less responsive to change to the
analog input.
