Encoder 1 Status (Ec.37) - KEB COMBIVERT F5 Anleitung

2.6

Encoder 1 status (Ec.37)

This parameter displays, by means of different status messages, the status of encoder and
interface. Dependent on the encoder only special messages are possible. All errors are only
set at control release, although they are already displayed in Ec.37.
The following value is displayed at correct operation:
16: position values are being transferred, encoder and interface are working
The following status messages triggers „Error Encoder Change" (E.EncC) because the
correct evaluation of the position is no longer guaranteed :
64: encoder is unknown and will not be supported
67: The signals of the incremental track are not correct, e.g. no encoder is connected or
the encoder cable is defective.
68: The signals of the absolute track are not correct. The absolute track at Endat, Hiperface
and SSI-Sin/Cos is digital. The absolute track at Sin/Cos is analog.
69: position deviation too high. The position determined by the incremental signals and
the absolute position (of absolute track, zero signal or serial selected) does no longer
correspond or cannot be corrected.
70: increments per revolution adjusted in the inverter does not correspond with encoder
increments per revolution.
71: interface type is unknown: Interface has not been recognized.
75: encoder temperature too high (message from encoder)
76: rotary speed is too high (message from encoder)
77: encoder signals are outside the specification (message from encoder)
78: encoder has internal defect (message from encoder)
92: encoder will be formatted. When writing an encoder with memory structures different
from the KEB-definition, their memories will be re-organized in such a manner that they
can be written. This procedure can take some seconds, depending on the respective
memory structure.
96: new value detected, because an another encoder is attached.
98: Interface is busy
Error E.EncC can only be reset via parameter Ec.0. Exception ! An error due to wrong
increments per revolution (value 70) is reset immediately, if the correct increments per
revolution are adjusted (from software 2.7). Attention, the modulation is released, when the
control release is still set!
The following status messages triggers „Error Encoder 1" (E.Enc1), if encoder data is
read:
97: KEB-reference is undefined. Memory structure of the encoder does not correspond
to the KEB-definition and therefore data cannot be read. The encoder is defined by
writing data. At F5-S the error is reset as follow:
• writing a position to Ec.2.
• perform a system position trimming
Following status messages trigger error „Error Hybrid" (E.HYb):
0, 255: no communication between interface and control card
