Error correction
Repeat the read or write service. If the error occurs once again, turn off the drive inverter
completely and turn it on again. Please consult the SEW Electronics Service If this error
occurs permanently.

Remedy: You are trying to exchange parameters with a drive inverter and have not con-
figured a parameter channel.

Autosetup
You can start up the UFI11A without a PC with the Autosetup function. It is activated with
the Autosetup DIP switch. Turning on the Autosetup DIP switch will execute the function
once.
The DIP switch will have to stay turned on afterwards. The function can be exe-
cuted once again by turning the switch off and on again. Upon activation of the
Autosetup feature, the UFI11A automatically searches for inverters on the lower-level
SBus and indicates this activity with a brief blinking of the SYS-FLT LED. Each inverter
on the SBus must be assigned a unique SBus address (P813). To avoid confusion with
data assignments, it is recommended to assign the addresses from address 1 ans wor-
king in ascending order according to the arrangement of inverters in the control cabinet.
The process image on the fieldbus side will be extended by three words for each located
inverter. The SYS-FLT LED stays on if no inverters are found. A maximum of eight in-
verters can be configured. The figure shows the process image for three inverters with
three words in the process output data and process input data. Following the search, the
UFI11A cyclically exchanges three process data words with each connected inverter.
The process output data are collected from the fieldbus, divided into blocks of three and
sent. The process input data are read by the inverters, assembled and sent to the field-
bus master.
Autosetup has to be executed only once. The detected configuration will be saved in the
non-volatile memory. See section "Installation and operation without PC."
Important: Execute Autosetup again in case you change the process data assignment
of the inverters connected to the UFI11A, because the UFI11A saves these values once
only during Autosetup. Likewise, the process data assignments (P860 ... P865) of the
connected inverters must not be altered dynamically either, for example by an IPOS pro-
gram, following Autosetup.
