Error 33 (Ade-): Motor Angle Detection Error; Error 34 (Ence-): Encoder Connection Error - Bosch rexroth EFC 610 Series Operating Instructions Manual

476/653
Diagnosis

13.4.18 Error 33 (AdE-): Motor Angle Detection Error

Possible reason
Internal error occurs during synchronous
motor angle detection

13.4.19 Error 34 (EnCE-): Encoder Connection Error

Possible reason
Wiring break or phase order error
Number of resolver poles and motor poles
does not match
The final calculated speed from encoder
inclusive pole numbers exceeds the al-
lowed range
The speed status of the encoder process-
ing is invalid
The angle status of the encoder process-
ing is invalid

Solution
Check the motor wiring
●
Check if output phase loss
●
Check if the motor is blocked
●
The converter can not receive the encoder signal
●
– Check the encoder card
– Check the wiring between the converter and encod-
er
– Check the encoder
Solution
Check if the wring of encoder is reliable
●
Check encoder wring break detection parame-
●
ter(H7.05 and H7.06)
Check encoder direction setting(H7.01)
●
Check encoder
●
time(H7.07)
Check resolver poles(H7.31)
●
Check motor poles(C1.11)
●
Check resolver poles(H7.31)
●
Check pulses per revolution of encoder(H7.20)
●
Check the grounding
●
Check if the cable with the shields grounded at two
●
ends
Check if the wring of encoder is reliable
●
Change encoder card
