SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
026 SCI interrupt
Cause An illegal processor interrupt has occurred. An EMC fault or a hardware
fault on the control module could be the reason.
Remedy – Check the plug-in connections
– Replace control module
Acknowledgement POWER ON
Stop response STOP II (SRM, SLM) STOP I (ARM)
027 HOST interrupt
Cause An illegal processor interrupt has occurred. An EMC fault or a hardware
fault on the control module could be the reason.
Remedy – Check the plug-in connections
– Replace control module
Acknowledgement POWER ON
Stop response STOP II (SRM, SLM) STOP I (ARM)
028 Actual current sensing during power-up
Cause When the current actual value sensing runs up, or in cyclic operation at
pulse inhibit, a 0 current is expected. The drive system then identifies
that no currents are flowing (excessive deviation to the theoretical cen-
ter frequency). It is possible that the hardware for the current actual
value sensing is defective.
Remedy – Check the plug-in connections
– Check whether the control module is correctly inserted
– Replace control module
– Replace the power section
Acknowledgement POWER ON
Stop response STOP II (SRM, SLM) STOP I (ARM)
029 Incorrect measuring circuit evaluation. Suppl. info:
\%X
Cause The motor measuring system has a motor encoder with voltage output
which requires a measured circuit evaluation with voltage input, or a
resolver with appropriate evaluation. Another measuring circuit evalua-
tion was identified.
Supplementary information: only for siemens-internal error diagnostics
Remedy – Check the plug-in connections
– Implement noise suppression measures (screening, check ground
connections, ...)
– Control module and encoder must be the same type (sin/cos or resolver)
– Replace control module
Acknowledgement POWER ON
Stop response STOP II (SRM, SLM) STOP I (ARM)
