代码 231115: <location>Encoder 1: Amplitude error track A/B fault (A^2 + B^2)

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 (root of A^2 + B^2) for encoder 1 exceeds the permissible tolerance. 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 thresholds are < 230 mV (obser ve the frequency response of the encoder) and > 750 mV. 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 Vr ms). The response thresholds are < 1070 mV and > 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.
