cause : Analog sensor channel B 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 (p4675).
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 (p4675).
For fault value = 3: check the range limit setting and increase it if necessary (p4676).
