SINAMICS alarms
207576 <location>Drive: Encoderless operation due to a fault active
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: Encoderless operation is active due to a fault (r1407.13).
The required response when an encoder fault occurs is parameterized in p0491.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy:
207580 <location>Drive: No Sensor Module with matching component number
Message value: Encoder data set: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: A Sensor Module with the component number specified in p0141 was not found.
Alarm value (r2124, interpret decimal):
Encoder data set involved (index of p0141).
Remedy: Correct parameter p0141.
207800 <location>Drive: No power unit present
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The power unit parameters cannot be read or no parameters are stored in the power unit.
Connection between Control Unit and power unit was interrupted or is defective.
Note:
This fault also occurs if an incorrect topology was selected in the commissioning software and this parameterization
is then downloaded to the Control Unit.
See also: r0200 (Power unit code number actual)
Remedy: - connect the data line to power unit and restart the Control Unit (POWER ON).
- check or replace the Control Unit.
- check the cable between the Control Unit and power unit.
- after correcting the topology, the parameters must be again downloaded using the commissioning software.
