Set 04-01 and 04-06 for analog signal verification.
All analog inputs (AI1, AI2) have a 1
st
order programmable input filter that can be adjusted when noise is present
on each of the incoming analog signal to prevent erratic drive control. Inverter reads the average values of A/D
signal once per (04-01/04-06 x 2ms).
Note:
Increasing the filter time causes the drive operation to become more stable but less responsive to change
to the analog input.
AI1 Analog Voltage input scaling examples by adjusting Gain, Bias & Slope parameters (04-02~04-05)
(1) Positive Bias type
(04-04= 0), Bias (04-03) and Slope (04-05).
