513 Measuring circuit error, direct measuring system abso-
lute track
Cause For absolute encoders with EnDat interface, this fault indicates an init-
ialization error.
Note:
Additional information on the reason for the fault is included in P1033
(DM diagnostics).
Remedy – Incorrect encoder cable type
– Check for sporadic interruptions (loose contact, e.g. when the drag
cable is being moved)
– Remove noise which is coupled in due to inadequate screening of the
cable by replacing the encoder cable
– Incorrect encoder type configured (e.g. ERN instead of EQN)
– Check the encoder, encoder cables and connectors between the
encoder and control module
– Replace control module
– Replace encoder
Acknowledgement POWER ON
Stop response parameterizable
514 Zero mark monitoring, direct measuring system
Cause A fluctuation in the measured values has occurred between 2 encoder
zero marks (encoder pulses may have been lost).
Note:
The encoder monitoring can be disabled using P1600.14.
Remedy – Use the original Siemens pre-assembled encoder cables (better
screening)
– Check for sporadic interruptions (loose contact, e.g. due to cable
drag movements)
– For toothed-wheel encoders, check the clearance between the
toothed wheel and sensor
– Check the encoder, encoder cables and connectors between the
motor and control module
– Check the shield contact, front panel, control module (upper screw)
– Replace the encoder cables or the control module
– Replace encoder
Acknowledgement POWER ON
Stop response parameterizable
