Message value: R track: %1 Drive object: All objects Reaction: A_INFEED: NONE SERVO: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3) VECTOR: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3) Acknowledge: IMMEDIATELY SINAMICS-Alarms Cause: The amplitude of the reference track signal (track R) does not lie within the tolerance bandwidth for encoder 2. The fault can be initiated when the unipolar voltage range is exceeded or the differential amplitude is initiated. Fault value (r0949, interpret hexadecimal): xxxx hex: xxxx = Signal level, track R (16 bits with sign). The unipolar nominal signal level of the encoder must lie in the range 2500 mV +/- 500 mV. The response threshold is < 1700 mV and > 3300 mV. The nominal differential 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. A signal level of 500 mV peak value corresponds to the numerical value of 5333 hex = 21299 dec. Note: The analog value of the amplitude error is not measur ed at the same time with the hardware fault output by the sensor module. The signal level is not evaluated unless the following conditions are satisfied: - Sensor Module properties avail able (r0459.30 = 1, r0459.31 = 1). - monitoring active (p0437.30 = 1, p0437.31 = 1). Remedy: - check the speed range, frequency characteristic (a mplitude characteristic) of the measuring equipment may not be sufficient for the speed range. - check that the encoder cables and shielding are routed in compliance with EMC. - check the plug connections and contacts. - check whether the zero mark is connected and t he signal cables RP and RN connected correctly. - replace the encoder cable. - if the coding disk is soiled or the lighting worn, replace the encoder.
