Código 231125: <location>Encoder 1: Amplitude error track A/B overcontrolled

Message value: A track: %1, B-track: %2 Drive object: All objects Reaction: A_INFEED: NONE SERVO: ENCODER (IASC/DCBRAKE, NONE) VECTOR: ENCODER (IASC/DCBRAKE, NONE) Acknowledge: PULSE INHIBIT Cause: The amplitude of track A or B for encoder 1 exceeds the permissble tolerance band. Fault value (r0949, interpret hexadecimal): yyyyxxxx hex: yyyy = Signal level, track B (16 bits with sign). xxxx = Signal level, track A (16 bits with sign). The nominal signal level of the encoder must lie in the range 375 mV to 600 mV (500 mV -25/+20 %). The response threshold is > 750 mV. This fault also occurs if the A/D converter is overcontrolled. A signal level of 500 mV peak value corresponds to the numerical value of 5333 hex = 21299 dec. Note for sensors modules for resolvers (e. g. SMC10): The nominal signal level is at 2900 mV (2.0 Vrms). The response threshold is > 3582 mV. A signal level of 2900 mV peak value corresponds to the numerical value of 6666 hex = 26214 dec. Note: The analog values of the amplitude error are not measured at the same time with the hardware fault output by the sensor module.
