2311 'Encoder signal'

  • Motor encoder defective
  • Encoder cable defective or not connected
  • Motor is equipped with a D encoder
  • Possibly A encoder with defective field plates
  • The SINE encoder monitoring can be switched off through ID32773
  • Overcurrent encoder supply voltage
  • Quadrant error of the encoder signals
  • Difference between analog angle and digital angle of the encoder too large

  • When comparing between analog angle and digital angle, an error has occurred

Additional Error Information (AMK Service)

  Info 1 1

Inadmissible level at the encoder input (operating)

 

 

2

The amplitude at the A/D converter input of an encoder track is less than 0.6 V
(normal level: 2 V). Filtration: 5x within 50 ms leads to shutdown.

 

 

3

In homing with T encoder or operation of synchronous machine with T encoder no feedback of the encoder.

 

 

4

In homing with T encoder or operation of synchronous machine with T encoder faulty transmission of the encoder.

 

 

5

In homing with T encoder or operation of synchronous machine with T encoder the internal error bit of the encoder was set.

 

 

6

On operation of synchronous machine with T encoder the drive has moved on system run-up.

 

 

7

Amplitude of a resolver signal at the A/D converter input is less than 0.6 V (normal level: 2 V)

 

 

12

The amplitude at the A/D converter input of an encoder track is too large.

AW

  As from AW 2.11 4696 error analysis (code) through monitor cell M 7CFF.
Data for T encoder also apply for S encoder

Error Removal

 

  • Encoder errors of the option card KU-/KW-EN1 are distinguished from the motor encoder by Info(I) + 100
  • Clear error or system OFF/ON (HW reset)
  • Check encoder cable for damage
  • Check encoder signals
