Frequently Asked Questions about 7V0ES108CD02
What does diagnostic readout 000001 mean?
The diagnostic readout 000001 has a fault number of FL01 and a fault name of IOC. This code is an instantaneous DC overcurrent (L, T). To fix this try the following.
-Tighten armature connections.
-Make sure the armature is grounded.
-Examine motor commutator for damage.
-Verify proper brush seating and tension.
-Mechanical problems- binding shaft, unreleased brake, vibration, gearbox, or load problems.
-IOC parameter is set to low.
-Current feedback isolator failure-check 1PL & DRPL.
-SCR failure; try SCR test.
-SCR misfiring -check VFB or CFB waveforms.
-Current regulator mistuned- adjust ILPPG, ILPIG, ILPDG, ILPDP (ADR019, 020, 021, 022).
What does the diagnostic code 000010 mean?
The diagnostic code 000010 has a fault number FL02 and a fault name of OVRSP. This code is an over speed (sensed by analog tach circuitry) (L, T)
- ADR073-SPDLM set to close to ADR068-REFSF and ADR071-REFLM.
-Speed regulator response is too high, reduce gain.
-Loss of field current.
