Code 233116: <location>Encoder 3: Amplitude error track A + B

Message value: Amplitude: %1, Angle: %2 Drive object: All objects Reaction: A_INFEED: NONE SERVO: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3) VECTOR: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3) Acknowledge: IMMEDIATELY Cause: The amplitude of the rectified encoder signals A and B and the amplitude from the roots of A^2 + B^2 for encoder 3 are not within the tolerance bandwidth. 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 < 176 mV (obser ve the frequency response of the encoder) and > 955 mV. A signal level of 500 mV peak value corresponds to the numerical value 5333 hex = 21299 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 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).
