Cause : Analog sensor position value exceeds limit value comes when the position value has exceeded the permissible range of -0.5 ... +0.5.

Fault value (r0949, interpret decimal):

1: Position value from the LVDT sensor.
2: Position value from the encoder characteristic.

For fault value = 1: Check the LVDT ratio (p4678) & check the reference signal connection at track B.
For fault value = 2: check the coefficients of the characteristic (p4663 ... p4666).
