Speed measurement
Ec.37 enc. 1 encoder status
Parameter Ec.37 "encoder 1 status" indicates the actual status of the encoder and encoder interface 1.
The encoder error is only displayed in the inverter status ru.00, if the control release is set.
The encoder status is always displayed in Ec.37.
If the error message: „35: ERROR! Encoder change“ (E.EncC) the exact error message can be read in Ec.37
in inverter state ru.00.
Ec.37: Encoder 1status
Value Explanation Error
0: no communication to the
interface no communication between interface and control board E.Hyb
16: transmit position Position values are transmitted, encoder and interface are correct no
64: encoder not defined
Encoder is unknown and is not supported E.EncC
68: no communication to
the encoder The signals of the absolute track are incorrect. The absolute track
at Endat, Hiperface and SSI-SinCos is digital, at SinCos it is analog. E.EncC
69: increase error counter Position deviation too large. The position, determined from the in-
cremental signals and the absolute position (absolute track, zero
signal or serial read out) do not agree or they cannot be corrected. E.EncC
70: Ec.01 unequal to the en-
coder type Adjusted increments per revolution of the inverter does not agree
with the encoder increments per revolution. E.EncC
71:
interface identification
Interface type is unknown:
Interface was not identified.
E.EncC
Ec.37 enc. 1 encoder status
Value Explanation Error
75: encoder temperature Encoder temperature too high (message from encoder) E.EncC
76: speed too high Speed is too high (message from encoder) E.EncC
7: int. encoder signals too low Encoder
signals are out of the specification (message from encoder)
E.EncC
78: int. encoder defect Encoder has an internal error (message from encoder) E.EncC
92: format encoder Encoder is formatted. When writing on an encoder, whose storage
structure does not correspond to the KEB definition, the storage
areas are reorganised, so they can be written on. This procedure
can take several seconds, depending on the available memory
structure.
E.EncC
96: new encoder identifier
New value recognized, because another encoder was connected E.EncC
98: damaged interface Interface is busy E.EncC
97: invalid data
KEB-identification is undefined. Memory
structure in the encoder
is not corresponding to the KEB definition and consequently the
data can not be read.
E.Enc1
255: no communication to
the interface no communication between interface and control board E.Hyb

Error encoder change
If the correct evaluation of the position is not given, then error "35: Error! Encoder change "(E. ENCC) is trig-
gered.
The error can be reset via parameter Ec.00 and from version 4.2 also via hardware or bus-reset.
An error due to wrong encoder increments per revolution (value 70) is immediately reset, if the correct number
of increments per revolution is adjusted.
