Display
Description
“H”: The motor controller 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 ).
For the “unsafe status”, no special display is intended; the standard status displays of
the motor controller are depicted.

Error messages
When an error occurs, the motor controller shows an error message cyclically in the seven-segment
display on the front of the motor controller. The error message consists of an “E” (for Error), a main
index (xx) and a 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 -.
Tab. 5.2 lists the error messages that are relevant for the functional safety in combination with the STO
safety function.
The complete list of error messages can be found in the hardware documentation
GDCP-CMMP-M0-HW-... of the motor controller.
Where an error message cannot be acknowledged, the cause must first be remedied in accordance with
the recommended measures. Then reset the motor controller, and check whether the cause of the er
ror, and the error message, have been eliminated.
