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 trigger error „Error Encoder Change" (E.EncC):
64: encoder is unknown and will not be supported
68: no encoder is connected. Encoder breakage recognition has triggered
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.
74: encoder temperature too high
75: speed too high
76: encoder signals are outside the specification
77: encoder has internal defect
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.
98: interface is damaged
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 trigger „Error Encoder 1" (E.Enc1) as the correct evaluation
of the position is no longer guaranteed:
97: KEB-reference is undefined. Memory structure of the encoder does not correspond to
the KEB-definition and therefore data cannot be read.
Following status messages trigger error „Error Hybrid" (E.HYb):
0, 255:no communication between interface and control card

Read/write Encoder 1 (Ec.38)

With Ec.38 the parameter are read/write from/to the encoder.
Value Function
1 Read out of the parameter. Then the parameter is reset.
2 Storing of the parameters in the encoder (only with supervisor-password and in nOP
status)
4 Automatic read out of the parameters during switch on
