Cause : Analog sensor channel A failed comes when the input voltage of the analog sensor is outside the permissible limits.

Fault value (r0949, interpret decimal):

1: Input voltage outside detectable measuring range.
2: Input voltage outside the measuring range set in (p4673).
3: The absolute value of the input voltage has exceeded the range limit (p4676).

For fault value = 1:
- check the output voltage of the analog sensor.

For fault value = 2:
- check the voltage setting for each encoder period (p4673).

For fault value = 3:
- check the range limit setting and increase it if necessary (p4676).
