官方故障排除步驟
[Cause of error] - The supply voltage Vcc(x) was out of range. - +4 = undervoltage Vcc(+5 V) The load from external components (e.g. encoders) is too large. - +6 = overvoltage Vcc(+5 V) The power supply unit is defective. - +14 = undervoltage Vcc(+15 V) The power supply unit is defective. - +16 = overvoltage Vcc(+15 V) The power supply unit is defective. - -14 = undervoltage Vcc(-15 V) The power supply unit is defective. - -16 = overvoltage Vcc(-15 V) The power supply unit is defective. [Error correction] - Inform your service agency. - Measure the supply voltage Vcc(x). - Vcc(+5 V) < +4.75 V Check the encoder connections. - Vcc(+5 V) > +5.50 V Exchange the power supply unit. - Vcc(+15 V) < +14.25 V Exchange the power supply unit. - Vcc(+15 V) > +16.50 V Exchange the power supply unit. - Vcc(-15 V) < -14.25 V Exchange the power supply unit. - Vcc(-15 V) > -16.50 V Exchange the power supply unit.
