Set 04- 01 and 04- 06 for analog signal verification.
Inverter reads the average values of A/D signal once per (04- 01/04- 06 x 2ms). Set scan intervals according
to the application and with consideration for signal instability or interference effects on the signal by external
sources. Long scan times will result in slower response time.
