Error message

B900 CC%d supply voltage %d

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.
