代码 231126: <location>Encoder 1: Amplitude AB too high

Message value: Amplitude: %1, Angle: %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 (root of A^2 + B^2 or |A| + |B|) for encoder 1 exceeds the permissible tolerance. Fault value (r0949, interpret hexadecimal): yyyyxxxx hex: yyyy = Angle xxxx = Amplitude, i.e. root from A^2 + B^2 (16 bits without 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 for (|A| + |B|) is > 1120 mV or the root of (A^2 + B^2) > 955 mV. A signal level of 500 mV peak value corresponds to the numerical value of 299A hex = 10650 dec. The angle 0... FFFF hex corresponds to 0... 360 degrees of the fine position. Zero degrees is at the negative zero crossover of track B. Note: The analog values of the amplitude error are not measured at the same time with the hardware fault output by the sensor module.
