Qué Significa el Fallo

Fault: Encoder 2: Amplitude alarm track A or B (A^2 + B^2)

Causas probables

• 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 of 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 < 230 mV (observe the frequency response of the encoder)

Solución y Primeras Comprobaciones Seguras

1. check the speed range, frequency characteristic (amplitude characteristic) of the measuring equipment is not
2. check that the encoder cables and shielding are routed in compliance with EMC.
3. check the plug connections.
4. replace the encoder or encoder cable.
5. check the Sensor Module (e.g. contacts).
6. if the coding disk is soiled or the lighting aged, replace the encoder.

Seguridad: no trabajes dentro del cuadro sin cortar la energía; si tienes dudas, consulta a un técnico cualificado.
