The X485 connector
The X485 provides a connection for the optional CIO-01 I/O module. For more
information, refer to CIO-01 I/O module for distributed I/O bus control user’s manual
(3AXD50000126880 [English]).
￭
Safe torque off (XSTO, XSTO OUT)
The XSTO input only acts as a true Safe torque off input on the inverter control unit.
De-energizing the STO input terminals of other control units (supply, DC/DC converter,
or brake unit) stops the unit but does not constitute a SIL/PL classified safety function.
￭
FSO safety functions module connection (X12)
In drives or inverter units with a compatible control program, an optional FSO safety
functions module can be connected to the X12 connector. The control program in
supply, brake, and DC/DC converter units does not support the FSO safety functions
module.
For more information on the FSO safety functions module, refer to the applicable FSO
module user's manual.
Note: Inverter modules and control units that have a sticker with the text “No FSO
support” are not compatible with the FSO safety functions module.
￭
SDHC memory card slot
The control unit has an on-board data logger that collects real-time data from the
power modules to help fault tracing and analysis. The data is stored onto the SDHC
memory card inserted into the SD CARD slot and can be analyzed by ABB service
personnel.
