Description
“H”: The servo drive is in the “safe status”.
This does not have the same meaning as the information on the status of the
safety function STO (Safe Torque Off). This can only be read off on the LED of
the safety module.
No special display is intended for the “unsafe status”; the normal status displays
of the servo drive are represented.

Error messages
When an error occurs, the servo drive shows an error message cyclically in the seven-
segment dis-play on the front of the servo drive. The error message consists of an E (for
Error), a main index (xx) and sub-index (y), e.g.: E 5 1 0. Warnings have the same number
as an error message. The difference is that a warning is displayed with a prefixed and
suffixed hyphen, e.g. - 1 7 0 -.
lists the error messages that are relevant for the
functional safety in combination with the SE-Power FS Safety Module STO.
For more information about other error messages, please refer to the corresponding
documentation, for example the relevant product manuals, the software manual or
the fieldbus- specific product manuals. See
Where an error message cannot be acknowledged, the cause must first be remedied in
accordance with the recommended measures. Then reset the servo drive, and check
whether the cause of the error, and the error message, has been eliminated.
