Código 232415: <location>Encoder 2: Amplitude error track A/B alarm (A^2 + B^2)

Message value: Amplitude: %1, Angle: %2 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The amplitude (root of A^2 + B^2) for encoder 2 exceeds the permissible tolerance. Alarm value (r2124, 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 is < 300 mV (obs erve the frequency response of the encoder). A signal level of 500 mV peak value corresponds to the numerical value 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 for sensors modules for resolvers (e. g. SMC10): The nominal signal level is at 2900 mV (2.0 Vrms). The response threshold is < 1414 mV (1.0 Vrms). A signal level of 2900 mV peak value corresponds to the numerical value of 3333 hex = 13107 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. Remedy: - check the speed range, frequency characteristic (a mplitude characteristic) of the measuring equipment is not sufficient for the speed range. - check that the encoder cables and shielding are routed in compliance with EMC. - check the plug connections. - replace the encoder or encoder cable. - check the Sensor Module (e.g. contacts). - if the coding disk is soiled or the lighting worn, replace the encoder.
