Function
Operating status
The device can display its operating status via an output (ready). For this, the output must be con-
figured accordingly (Px.11203 or Px.11204
è
Tab. 154 Configurable output signals at X1A.9 and X1A.10). To configure the output using the plug-
in, see
è
page "Digital I/O".
The configured output is active if the servo drive is ready for operation.
If there is an error, the configured output is inactive.
Switch-on behaviour
After the device is switched on, it runs through the start-up phase. E. g. it runs the following items:
–
The relevant EEPROM data are imported.
–
The factory parameter set is loaded.
–
The customer-specific parameter set is imported.
–
The parameterised configuration is compared with the physical configuration (actual/setpoint
comparison).
–
The software components are initialised (I/O mapping, monitoring, limitations etc.).
–
If the power supply is correct, the intermediate circuit is loaded.
If the start-up phase has been completed without errors, the device switches to the "Ready" status or
the "Profile" status depending on the parameterisation

Parameters and diagnostic messages, Parameter Px.10234.
The start-up phase may take several seconds, depending on the encoder used.
Switch-off behaviour
When switching off the logic power supply the device detects that it has dropped below the defined
threshold value and reacts as follows:
–
the output stage is switched off
–
with multi-turn encoders the multi-turn position is saved in the EEPROM
–
the operating hour counter is saved
è
–
the outputs are moved to a defined safe status
–
a corresponding message is generated
–
the last messages are saved in the diagnostic memory.
When switching off the power supply the device detects that it has dropped below the defined
threshold value and reacts as follows:
–
a corresponding message is generated
–
a stop is initiated with the parameterised category
